Battery Talk

Although the lithium-ion Lenovo thinkpad r61e battery has little memory effect than nickel-cadmium battery, memory effect of the principle is that crystallization, there will be little reaction in the lithium batteries. However, lithium-ion battery capacity will continue to decline after repeated charge-discharge, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, plug; from the chemical point of view, is the active anode material is passive, there’s the other side to form a stable compounds. Physics will appear on the cathode material gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of the free movement of the number of lithium-ion.

Over-charging and over-discharge, lithium-ion Ibm thinkpad t400 batterywill damage positive and negative permanently , from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium-ion and makes it appear lamellar structure collapsed, over – Rechargeable lithium-ion will too hard go into the negative carbon structure, causing some of the lithium-ion can no longer be released. This is why lithium-ion batteries are usually equipped with charge-discharge control circuit causes.

if the temperature is Not suitable, it will lead to producing the other chemical compounds that we do not want to see inside the lithium-ion Ibm thinkpad t40 battery, so many of the lithium-ion batteries are being set up between the protective negative temperature-controlled diaphragm or electrolyte additives. In the battery temperature to a certain case, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, the battery is no longer to heat up, to ensure that the battery charging temperature is normal.

Our battery maintenance view is:

1. No need to ensure that every time a re-release END electric charge
2. A period of time to do a protection circuit placed under the control of deep-charge battery power to amend the statistics, but it does not improve the actual capacity of your sony vgp-bps5 battery.
3. A long time without the battery, should be placed in the shade in order to weaken its internal self-passivation reaction speed.
4. Protection circuit is also able to monitor the battery self-discharge, long-term without the battery should be charging to a certain degree of power to prevent self-discharge of batteries in storage in the discharge of excessive lead to excessive damage. In fact, there is not much to take into account the battery use of attention, in other words is taken into account is not much use. The number of times a cell can use, and perhaps more from the Ibm thinkpad t61 battery itself, differences in the manufacture of individual differences, rather than use.

Researchers in Spain and the United Kingdom are reporting development of a new electrode material that could ease concerns about the safety of those unbiquitous lithium-ion (Li-ion) batteries, while giving Li-ion batteries a power boost, according to a new study.

Li-ion batteries(thinkpad x200 battery , thinkpad t400 battery , lenovo n100 battery) power an increasing number of laptop computers and portable electronic devices. They are now being eyed for motor vehicles of the future. However, recent recalls of millions of Li-ion batteries due to overheating have raised safety concerns, with researchers seeking new materials to make safer, more powerful batteries.

In the new study, M. Rosa Palacín and colleagues compared the performance of Li-ion batteries made with electrodes composed of lithium nickel nitride (LiNiN) to conventional Li-ion batteriesthinkpad x200 battery , thinkpad t400 battery containing carbon electrodes. The new materials are more efficient than the conventional electrodes and less likely to overheat, the researchers suggest. They note that “further improvements can be envisaged by changing the reaction conditions and the processing of the electrode.”

The study,”Towards New Negative Electrode Materials for Li-Ion Batteries: Electrochemical Properties of LiNiN,” is scheduled for the March 11 issue of ACS’ Chemistry of Materials.

Despite all the technological advances in today’s mobile phones, there are still some properties that the manufacturers may be a target of choice, but so far does not necessarily seem to be reached. This includes, among other things, the problem is that the currently used battery materials to reach the maximum of their reserves through active use of mobile phones for voice calls and sending text messages after a few hours,such as Pavilion ZV5000 Battery . For years, manufacturers are hoping for the big breakthrough in the development departments, which could mean that the devices could be significantly more powerful than before.

The ideal in this respect is well produced, cell phones and smartphones, which can give consumers generally on the availability of a power outlet for recharging. This goal is achieved now conditioned by the first so-called “green” cell phones that work with solar panels and allow for charging of the Pavilion DV1000 Battery using solar power, even where there is no access to the grid. The Finnish manufacturer and leader in the wireless platform for Nokia would be a great step to have succeeded, the consumers new possibilities and freedoms in the mobile phone is designed to provide applications.

Allegedly, the recent media reports in various scientific journals such as the journal The Scientist, suggests that it is in the house of Nokia is no longer just in the early stages of research, but the Group has even been filed in the U.S. a patent application. For several years, the experts of the company are working on alternatives to supply electricity from mobile phone Ibm thinkpad t61 battery . Under the plan, allegedly, load cell phones and other electrical appliances in the future on a technology called “energy harvesting” to. This is why, according to the articles that provide the owners with their movements for a downright automatic loading.

Remain more mobile phone users (by Nokia in the central area of mobile communications), the faster the load on the phone at the end. Jogger strollers might even say, or were, so to speak, are due to human Stechdose for their mobile phones in this way. The approach requires that the heavy parts are mounted inside the phone on rails which in turn have nothing fixed, but flexible. Through so-called piezoelectric crystals, which are compressed on the rails, is in the course of movement of the mobile carrier of electricity to be generated, which in turn is transferred to the Ibm thinkpad t400 battery .

Obvious that this is not necessary for a full charge movement workload can be achieved with an hour of exercise for Ibm thinkpad t40 battery . For experts, however, this environmentally conscious approach – Nokia pursued in addition to this, other ideas that would lead to lower demand for electricity – a first step to meet the one hand, the increasing power requirements of the new powerful smartphones. Above all, the system can, if successful, ensure that the few times it should be above the outlet less closely together. Precise data on the possible implementation of marketable a few days ago a patent was applied for the handset manufacturers still unknown. But the message from an already successful: The market has already given new fodder.

Infinite Power Solutions (IPS) of the U.S. private technology companies invented such Thinergy Micro-Energy Cell (THINERGY MEC),its professional name is called solid-state thin-film a1185 battery .

But, at present this is only the ultra-micro-batteries, and used in some special areas, such as it is installed in the inside of cardiac pacemaker . Its power is far from enough to support an ordinary cell phone.

Now the Stamp Size of smallest model THINERGY MEC is square 3 cm, thickness is less than 0.2 mm.

Small but capable THINERGY MEC does not contain any heavy metals or toxic chemicals without the non-liquid or organic polymer electrolyte from aspire 3000 battery , using ultra-thin and highly flexible to package.

Lightweight, stable nature can make it deeply embedded and laminated to the printed circuit board or other materials.for the computer alone, if each disk, the chip is embedded in it, it’s apparent to be easy for the burden on the power of many.

• Magic function

Although appearance of THINERGY MEC is unique , but the functionality is very strong.

Conventional batteries are broadly divided into two types: rechargeable batteries and disposable batteries. Generally for its long life and a repetition rate high esteem ,the rechargeable TravelMate 2440 series battery is esteemed by the majority of electronics manufacturers, while the disposable batteries are based on the characteristics of high power.

THINERGY MEC, who also has the above two features. It can be charged, and can also maintain a high energy.

THINERGY MEC charge can be completed within ten minutes, while the leakage rate is a low loss of only 1% per year, life is more than a decade. On the current test results, if the battery is 100% discharged, THINERGY MEC rechargeable can be charged for 10000 times, you can save 80% capacity. By contrast, the existing battery is 50% discharged ,the thinkpad x60 battery life is 1000 times .

for charging more times, THINERGY MEC is not enough to become a revolutionary product. Amazingly, it can not be charged , and permanent used .The reason is in addition to the ordinary charge form – beyond the power plug, THINERGY MEC can also convert light, RF radio frequency, power, thermal energy into electrical energy to storage.

In other words, if the energy is combined with the environment, THINERGY MEC can provide a permanent power, and achieve more than a decade of maintenance-free operation.

• Micro-electronic cardiac

However, at present, THINERGY MEC has not yet can be used in everyday consumer electronics field.

At present there are four kinds of THINERGY MEC, the main difference is the power difference. the available now is the power of three large, but the maximum capacity of TravelMate 2440 battery is 2.5 mAh, however. The ordinary generating capacity is 5, battery 1000 mAh or more. In other words, THINERGY MEC’is not designed for “light bulb” service.

However, due to size, charge and discharge frequency, self-produced electricity and other characteristics, THINERGY MEC is very suitable for useing in wireless sensor nodes, plant into the type of medical equipment, military equipment, such as micro-miniature electronic products, but also can be used as back-up power supply chip selection.

I hope that one day, this battery can not only embedded in people’s heart pacemaker, but are also able to be used in household appliances such as cookers and hair dryers.

1. A new battery is usually discharged with very low capacity. for the new battery packs, It is strongly recommended that you can refer to the user guide of your electronic device for charging instructions.
2. The new thinkpad x60s battery must (circled achieve fully discharged and recharged) achieve three to five times for their optimal performance.
3. Rechargeable battery are unused for a long period undergoing their self-perception. Thus, it should always be kept in a fully charged condition and in a cool, dry and clean place.
4. To the best performance of thinkpad x60 battery ; pack, it is very advisable to circle (fully discharging and recharging) it at least once a month.
5. It is normal is warm for new vgp-bps2c battery, if not be collected or used. However,if the battery is excessively hot,then you must pay special attention to it . This may indicate there is a problem with the charging circuit of the electronic device. Please contact a qualified technician if necessary.
6. New laptop batteries are too heavy. Sometimes, your electronic device may indicate a fully charged condition is about 10 to 15 minutes, when the new battery will be charged from the first time. If this is the case, remove the battery and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be calculated. If this is the case, a suggested solution tries to keep the thinkpad t60 battery from the device and insert it again.

Compared to traditional cameras, digital cameras have the particularly great demand for electricity. because lithium batteries and nickel-metal hydride batteries can be reused and need large power,so they are also more and more popular for digital camera users. But regardless of a lithium vostro 1500 battery or nickel-hydrogen batteries, we need pay more attention to using and saving a variety of battery.

Ni-MH battery has memory effect, this effect would reduce the overall battery capacity and usage time. As time goes on, less and less stored charge, the battery also will be consumed faster and faster. Therefore, we should try to run out the electricity. If you use a dedicated lithium bn-vf808 battery  or lithium-ion battery, no memory effect problem need not to think about.

In everyday use, they must pay attention to maintaining the integrity of the Dell xps m1330 battery insulating paper, once they are damaged, it should be tightly pasteted by tape. Check the battery’s electrodes whether there is oxidation or not, mild oxidation can be polished off, but if a serious case of oxidation or loss ,we should immediately replace them with new batteries. Meanwhile, in order to avoid power loss, need to keep contact points at both ends of the battery and battery lid clean, if necessary, you can use a soft, clean dry cloth and gently wipe off the battery. Using a small eraser(For example, the kind of a pencil head) to clean metallic contacts inside the battery pack, but can not use cleaning agents with the solubility of a cleansing agent.

Also, when you plan a long time do not use digital camera, must take out the battery from a digital camera, or charger , and it is fully discharged and then stored in a dry, cool environment, but not to place the battery and the general metal objects stored together, this point is particularly important for non-rechargeable batteries,such as bn-vf823 battery .

Laptop battery purchase attention

We often see the 50$ original Dell laptop battery or Apple battery in Ebay. We are also asked about that : your battery is a original battery or not. You should realize that : the battery with the original Brand logo maybe not the original battery.

According to my 5-6 years market experience of laptop battery industry , http://www.battery4.us share some battery purchase note with you.

1. Now the laptop battery market is confusedly. Many low-cost “original” laptop batteries flooded the market. Most of these batteries are the original renovation battery (using a low-quality cells); the same pack with the original battery, no protection battery quality; Some of it is a true original stock battery, but most of them are produced for a long time (even more than two years).

The battery performance greatly reduced, as we all knows laptop battery is a consumable items, lose the performance even in stock; And there is no real brand new original laptop battery in the market, because battery manufacturers will be asked to produce the detail terms number battery by laptop manufacture, according to the amount of customized. The original laptop battery has an official one-year warranty, the market prices are mostly in the $150-200.

2. We all know, the lowest-cost maintenance approach to repair laptop battery (as Lifebook T4220 battery ) is replace the cells. Note that this is the least, sometimes you may have to replace protection board. A good imported batteries cell such as Sanyo, Sony, Samsung and other brands are 5.0$ or more in the market, high-capacity of 6$. Replaceme a 6-cell battery will takes about 35$ dollars or more.

Therefore, we can estimate the original laptop battery Price: 6 cell + battery protection board + enclosure + test fee + R & D costs + packaging + transportation + labor costs + a series of warranty after-sales and other costs, original laptop battery ex-factory price at least 60$, so You should carefully select these 40-50$ “original” Toshiba laptop battery in the market .

3. The main difference between High-quality and low-quality laptop battery Cells

I make the laptop battery as example to explain the diffenence for everyone. There are three kinds laptop battery in the market as following:

1. An original laptop batteries, good quality, need not any evaluation.
2. The famous brand laptop batteries like http://www.battery4.us, high quality and excellent price (the people’s favorite kind laptop batteries).
3. Waste batteries and “original batteries” gave as a gift when buying laptop, usually only stand 2 hours or less. Because these two kinds batteries capacity failed to reach the nominal capacity of standby time. So it is the worst laptop battery (Dell Inspiron 6000 Battery).
4. The replacement battery between 60$-100$ in the market. The battery can standby for 3-4 hours as original battery. But after used abour 10-12 months. The battery capacity reduced a lot or even scrapped. Although it can achieve the nominal capacity and the same standby time as original battery. But the other properties of the battery such as the battery charge and discharge times, the battery anti-aging properties simply can not up to standard. So it can only use 10-12 months.

Most of the 3-6 warranty months warrany “Original battery” and “OEM Dell XPS M140 Battery ” on the market are made of neutral batteries: It achieve the use of nominal time, but it is difficult to achieve the standard charge and discharge times, battery aging fast, average life between 3-6 months. (so they can only guarantee the battery up to six months).

In the end if you want to buy the high quality cheap price battery, just buy the 1 year warranty battery replacement in http://www.battery4.us/. Do not buy the “6 month or less warranty Original battery” in Ebay. As I know I saw many “original sony VGP-BPS8 VGP-BPS9 battery” in Ebay.

Germany EVONIK Gazprom March 1, said it would jointly develop the world’s largest storage capacity of lithium ceramic latitude d600 battery with co-Daimler Motor Company and a number of R & D institutions to , so that wind and solar power can be achieved up to high-capacity, low-cost storage in future .

The company said that for this power plant to be developed, the company plans to use the latitude d820 battery for the electric car designed for a combination of ceramic storage technologies, polymer lithium-ion battery technology. This technique is safe and good, small size and high cycle stability and so on.

R & D projects as a first step, the company plans to start build a power one megawatt of electrical storage devices in the power station of Saarland in western Germany , the required storage capacity of the latitude d830 battery is about 700 kilowatt hours and the volume is only a power or hybrid electric vehicle battery 40 to 50 times. In theory, if the electrical storage devices charge and discharge is once every 15 minutes, it can ensure that 4000 families a year to power.

EVONIK chairman said that the new vostro 1500 battery and apple a1185 akku.once successfully developed, it will be able to solve the introduction of wind and solar power to the grid caused by power supply fluctuation. Industry experts pointed out that only German on the scheme renewable energy generating capacity will be increased to half of the total generating capacity by 2050, other EU countries will also be a growing number of wind power and solar power supply network. This gives renewable energy storage and transmission technology, higher and higher requirements. Experts predict that the future of advanced electrical storage devices will be billions of euros each year a huge market.

Zinc – manganese dioxide dry battery (zinc-manganese dry battery) referred to as zinc-manganese batteries, take the Jvc bn-v428 for example , manganese dioxide is used as cathode active material, the original battery use zinc negative electrode as active material. Cells using ammonium chloride and zinc chloride or potassium hydroxide in aqueous solution as electrolyte, surface starch, film coated paper or special paper is used as isolation layer, usually made of gel or electrolyte solution absorbed in the isolation layer, vector, was not flowing state, so called dry. Zinc-manganese battery nominal voltage of 1.5 volts.such as the battery for Samsung sb-l160 . Electrolyte solution are divided into thress types by the use of different types ammonium chloride ,such as ammonium chloride, zinc chloride and alkaline. Ammonium chloride and zinc chloride-type zinc-manganese battery manganese battery is known as the neutral (or carbon-zinc batteries, carbon zinc batteries).

Zinc-manganese batteries is divided into cylindrical shape (with “R” indicated) and non-cylindrical battery (with “P” indicated) two kinds,according to their size and electrochemical system named after the battery,like the Samsung sb-lsm80 battery. However, prior toOctober 1990,a non-cylindrical-shaped battery is divided into shut-ping (using the “F” indicated) and side (moment) form (with “S” indicated). Dimensions mentioned here do not mean a whole cell (battery) form factor, but one of the single cell (cell) form factor. For example, the battery 6LR61 the overall shape is square (moment) form, but that one of the single cell LR61 is cylindrical, so the battery model is based on the shape of single cells “R” named. Shut by several cells in series flat-shaped zinc-manganese composite made of single cells, often referred to as stacked-type battery.

Neutral zinc-manganese batteries can be divided into cardboard paste-type cells and batteries,for one thing ,the Sony np-qm91 .according to the difference between isolation layer ; according to the level of battery capacity,they also can be divided into ordinary products (S), high-capacity (C) and high-power (P) 3 grades, but the recent IEC standard battery has been canceled C-, neutral zinc-manganese battery-free electrochemical system code. Alkaline zinc-manganese batteries combined in form and pre-electrochemical system, code-named code-named “L” said.

Zinc-manganese battery is the oldest of the original battery for Canon lp-e5 . the battery is still the leading civilian products. With the continuous development of science and technology, neutral, alkaline zinc-manganese batteries will gradually be replaced by zinc-manganese batteries. when the IEC standard is currently changed ,the battery C-type was removed .

How to Choose Battery

1. Choose the “National Inspection-free”, ” famous brand” (such as Samsung sb-l160 )logo and the local brand-name batteries battery products, the quality of these products have a certain protection.
2. According to the requirements of electrical appliances, select the appropriate cell types and specifications of size and power apparatus ,and according to the size and characteristics of power, purchase equipment for electricity battery.
3. Pay attention to checking the battery production date and shelf life, buy the recent production of the battery (for one thing ,the new Nikon en-el7 battery), the new battery have good performance.
4. Pay attention to checking the appearance of the battery,should buy packaged refined appearance neat, clean, no signs of battery leakage.
5. Pay attention to the battery symbol, the battery should be marked with the production mark the make, battery polarity, the battery model, nominal voltage, trademarks, etc.; sales package (such as two heat-shrinkable, or four heat-shrinkable, or hang tag card ) It should have the Chinese factory, manufacturing date and shelf-life or shelf life of the deadline marked the implementation of the standard number. Purchase of alkaline zinc-manganese battery ALKALINE, or whether one should look at models LR words.
6. Due to mercury batteries harmful to the environment, in order to protect the environment, the purchaser should select the label marked “mercury-free”, “0% mercury,” and “no added mercury” indication of battery,take the Nikon en-el3e for example .

Should pay attention to the use of batteries :

1. Electrical appliances and battery contacts should be clean, if necessary, wipe with a damp cloth until the dry loaded correctly marked by polarity. When loading the battery to see for the polarity ( “+” and “-”) to install an extremely important ,and should be the specification requires the installation of electrical appliances with the use of the recommended batteries; do not follow instructions required will lead to equipment failure, damage to electrical appliances and / or battery.
2. Should also replace all batteries in a battery, do not mix old and new batteries together; the same model but a different type or brand of battery electrochemistry do not mix, such as Canon nb-4l and Canon nb-3l , and otherwise it would be a set of batteries in use in some of the battery over-discharge state, thereby increasing the possibility of leakage.
3. Can not heat for a one-time or charge the battery for recycling, or they may explode.
4. Can not make the battery short-circuit to avoid battery leakage and resulting damage to the heat generated by insulated packaging.
5. Electrical appliances should be removed from the battery for a long time without using , the power should be closed after using to avoid the battery going on to discharge its internal chemical reaction took place which led to leakage of the negative.
6. Used batteries for sony vgp-bps2a should not arbitrarily discarded, as far as possible separated from other garbage running.
