 to maintain what is right? This problem has plagued many loyal users of mobile phones, including me. In some access to information, not long ago had the opportunity of consulting a professional in the electrochemical and Dr. Reading a well-known domestic battery, deputy director of the Institute. The recently acquired some knowledge and experience to write out for our readers you.

The lithium-ion battery cathode material of lithium are normally composed of active compounds, the negative electrode is a special molecular structure of carbon. Common cathode material for the major components of LiCoO2, charging, the battery added to the polarization of the potential positive force the release of the lithium-ion compounds, embedded negative elements were arranged in layers in the structure of carbon. Discharge, lithium-ion from the lamellar structure of the carbon in precipitation, and re-cathode combination of compounds. Lithium-ion movement have had a current.

Although the principle of chemical reaction is very simple, but in the actual industrial production, to be considered much more practical problems: the cathode material additives required to maintain sufficient number of release activity, the negative electrode materials at the molecular structure of the level needed to design To accommodate more lithium-ion; fill in between the electrolyte is negative, in addition to maintaining stability, but also need to have good electrical conductivity, reducing theHP battery

internal resistance.

Although the lithium-ion batteries have a little nickel-cadmium battery memory effect, the memory effect is the crystallization of the principle, lithium batteries have virtually no reaction. However, the number of lithium-ion battery charge after the release of capacity will continue to decline, the reasons are complex and diverse. The main negative electrode material itself is a positive change from the molecular level, the anode is on the capacity of lithium-ion hole structure will gradually collapse, plug; from the chemical point of view, the negative electrode material is being passive activity, the reaction appears to form a stable of other Compounds. Physics will appear on the cathode material off gradually, and so on, a word ultimately reduces the battery can be free in the process of charging and discharging of the lithium-ion mobile number.

This is why lithium-ion batteries are usually equipped with charge-discharge control circuit.

to generate a chemical reaction that we do not want to see the compounds, so many of the lithium-ion batteries are being set up between the negative temperature of the protective membrane electrolyte or additives. In the battery reaches a certain temperature, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, is no longer the battery temperature to ensure that the battery temperature normal.

The deep sufficient to put lithium-ion batteries to upgrade the actual capacity of it? Experts clearly told me that this is meaningless. They even said that the use of the so-called three times before the release of the all-sufficient "activation", in both of them, Dr. knowledge, it also could not figure what is necessary. But why put a lot of people filling the deep after Battery Information marked in the capacity of this change? Will be referred to the back.

Lithium-ion batteries are generally managed with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. I personally believe that the use of "the use of a month or so should take charge full-time" approach should be the main role is to register these amendments in the wrong value, making the hp F2299A battery , hp F3172A battery , hp Pavilion ZT1000 battery

charge control and battery with a nominal capacity of the line with the actual situation.

The main charge control chips to control the battery charging process. Lithium-ion rechargeable battery process is divided into two phases, the current phase of the fast charge (when the battery indicator light yellow) and reduced voltage current phase (the battery indicator light flashes green. Filling phase of the fast current, battery voltage and gradually increase To the standard battery voltage, then under the control of the chip into the phase of the constant pressure, higher voltage is no longer sufficient to ensure that they are too, along with the current battery of 0 to weaken gradually increased, and the final charge.

Statistics chip power consumption records through the discharge curve (voltage, current, time) can calculate the sample battery power, this is what we read in Battery Information in the wh. Value. The lithium-ionApple battery

Finally, my battery maintenance view is:

1. Deliberately do not have to guarantee that each time a re-release END electric charge;

2. For a period of time to do an Protection of the circuit under the control of the deep to take charge of battery power to amend statistics, but you will not increase the actual capacity of the battery.

3. The batteries do not have long-term, the shade should be reduced to its own internal passive reaction speed.

4. Protection circuit is also able to monitor the battery self-discharge, do not have long-term battery should be sufficient to prevent a certain degree of power in the storage

self-discharge of excessive lead to excessive discharge of the damage.

In fact, the battery does not take into account the use of too much attention, in other words is also taken into account is not much use. A battery to the use of the number of times, the difference may be more from its own battery manufacturing of individual differences, rather than using the method. Select a good word-of-mouth brand of mobile phones is the use of long-life battery in the future of one of the security.
