Lithium-ion laptop battery cathode materials often have the active compounds of lithium, the anode is a special molecular structure of carbon. Common cathode materials for the major components of LiCoO2, charging, the battery and the polarization of the positive potential of the compound to force the release of Li-ion, the negative elements are embedded in a layer of carbon in the structure. Discharge, lithium-ion from layers of carbon in precipitation, and positive re-integration of the compound. Lithium-ion Mobile has current.
Although the principle of chemical reaction is very simple, but in the actual industrial production, the need to consider the practical problems are many more: the cathode material additives need to maintain multiple-charge of the activity, the negative electrode material needs at the molecular level to design the structure to To accommodate more of the lithium-ion; filling in between the electrolyte is negative, in addition to maintaining stability, but also need to have good electrical conductivity and reduce the resistance of the asus battery.
Although lithium-ion batteries are nickel-cadmium battery rarely the memory effect, the memory effect is the crystallization of the tenets of the lithium batteries in almost does not produce such a reaction. However, in lithium-ion battery capacity after repeated charge-will continue to decline, its causes are complex and varied. Are mainly negative material itself changes, from the molecular level, is on the negative electrode capacity lithium-ion structure of the hole will gradually collapse, plug and from the chemical point of view, is negative materials are passive activity, a stability of the reaction of the other Compounds. Physics will appear on the cathode material gradually falling off, and so on, a word ultimately reduce the A2 battery charging and discharging be free in the course of the lithium-ion mobile number.
Over-charging and excessive discharge, will lithium-ion battery anode is the cause permanent damage to the molecular level, can be intuitive understanding of the excessive discharge of carbon anode will lead to excessive release of its lithium-ion layers and make structural collapse, excessive Rechargeable lithium-ion would be too hard into the carbon anode where the structure and makes some of these lithium-ion can no longer be released. This is also why lithium-ion batteries are usually equipped with charging and discharging of the reasons for the control circuits.
Not suitable for the temperature, will trigger internal lithium-ion battery reaction of other chemicals we do not want to see the compounds, so many of the lithium-ion battery anode is between a protective divide the temperature control or electrolyte additives. The battery is heated to a certain cases, the composite membrane film hole closed or electrolyte degeneration and increase the resistance of the A3H battery until the opening, batteries no longer warming up to ensure that the batteries temperature normal.
The deep-charge lithium-ion batteries can enhance the actual capacity? » Experts clearly told me that this is meaningless. They even said that the use of so-called pre-charge all three of the “activation” in their knowledge of Dr. two, this is also what is necessary Xiangbu Tong. But why many people take charge after deep Battery Information, a marked change in capacity will be «behind will be mentioned.
Lithium-ion batteries are generally managed with a chip and charge control chips. Management of these chips in a series of the register, have the capacity, temperature, ID, charging status, the number of discharges, such as numerical. These values in use will gradually change. I personally think that, the use of the “use of about one month should be sufficient and all-time” approach should be the main role is to amend these registers, the value of misconduct, making the battery charge control and a nominal capacity of the M2 battery anastomosis of the actual situation.
Charge control chips main control battery charging process. Lithium-ion rechargeable battery process is divided into two phases, fast charge constant current phase (the battery indicator light was yellow) and the constant pressure decreasing current phase (the battery indicator light was flashing green. Constant fast filling stage, the battery voltage gradually increased To the standard battery voltage, then under the control of chips into the constant pressure stage, the higher voltage is no longer sufficient to ensure that the current battery, along with the rising gradually reduced to zero, while the final charge.
Statistics chip consumption by recording discharge curve (voltage, current, time) can be calculated sampling battery power, this is what we read in Battery Information in the wh. Value. The lithium-ion batteries in use on many occasions, the discharge curve will change, if chip has been no opportunity to read the full discharge of a curve, calculated by the electricity that is not accurate. Therefore, we need sufficient depth to calibrate the M2000 battery -chip.
Finally, I battery on the maintenance of view is:
1. Deliberately do not have to guarantee that each time, the End-replenishment;
2. For a period of time to do a circuit protection under the control of the deep-sufficient battery power to amend statistics, but it will not improve your battery’s actual capacity.
3. Do not have long-term battery, should be placed on a cool place to weaken its own internal passive reaction speed.
4. Circuit protection is also able to monitor the PCGA-BP2NX self-discharge, long-term without the battery, should be sufficient to prevent a power storage batteries in the self-discharge in the discharge of excessive lead to excessive damage.
In fact, there are not too many batteries to take into account the use of attention, in other words taking into account also is not much use. A battery can use the number of times, maybe more different from its own battery manufacturing of individual differences, rather than using the method.
