Analyses the composition of cell phone lithium battery and charging method

Source: 2020 - 03 - 31 as hits: at a time, composition of the cell phone lithium batteries, cell phone lithium battery is mainly composed of plastic shell, lithium core, maintenance of circuit board and recoverable fuse. Some manufacturers also equipped with, such as the NTC, identify components such as resistors, vibration motor or charging circuit. Each part function is as follows: ( 1) Lithium battery: provide charging power supply. ( 2) Maintenance of circuit board: prevent the battery overcharge, overcharge, short-circuit. ( 3) Recoverable fuse ( PTC(列车自动控制系统) : thermistor play a role in high temperature maintenance, after the circuit board fault dual maintenance. ( 4) Restorer fuse ( NTC) : negative thermistor, induction to the battery internal temperature, keep the battery in low temperature condition. ( 5) Resistance: identification, cannot use of galvanic battery and the battery is very important. The battery has several levels, including class A and class B cell battery. 2, cell phone lithium battery correct way of charging and discharging my mobile phone is the proper way to lithium ion batteries using lithium ion batteries, so as not to recall and activation problems. Charge for the first time does not need to be more than 12 hours, and nickel only need four hours. Lithium ion battery life depends only on the charge number, charge number is about 1000 times. Standby time related to the operation. Mobile phone sellers said, however, the first three time charge need 12 hours. What is this? How to charge: when using lithium battery, battery should be paid attention to after a certain period of time, will enter a dormant state. At present, the capacity is lower than normal, time will also be shortened accordingly. Lithium battery is easy to activate, however, need only 3 to 5 normal charge and discharge cycles, the battery can be activated, restore its normal capacity. Because of the characteristic of the lithium battery itself, its recall effect is poorer. As for the lithium batteries' activate ', a lot of people say charging time must be more than 12 hours, need to be repeated 3 times to activate the battery. Claimed that the first three time charge need to be more than 12 hours, apparently was a continuation of the nickel cadmium battery and nickel metal hydride batteries. So that is misleading. Lithium and nickel battery charging and discharging characteristics are quite different, I can tell you very clearly, all serious formal technical data I reviewed stress, overcharge and overdischarge lithium battery can cause a lot of damage, especially liquid lithium ion battery. Therefore, it is best to according to the standard time and methods to collect fees, especially for no more than 12 hours. In general, is introduced in the instructions for mobile phone charging mode is suitable for mobile phone standard charging mode. In addition, the lithium battery cell phone or charger will automatically stop after a full charge, and nickel battery charger does not show continued charging more than 10 hours of the so-called 'trickle. That is to say, if your lithium-ion battery fully charged, it will also be on the charger is charging. However, we cannot guarantee that the battery not the maintenance charge and discharge characteristics of the circuit, its quality is safe. As a result, your battery may be wandering at the edge of the danger for a long time. This is also our object to a longer time to charge for another reason. In addition, if the part of the mobile phone charge after a period of time not to take out the charger, the system will not stop charging, also will begin to charge and discharge cycle. Maybe it's manufacturers have their own intentions, but it apparently does not favor the battery and the life of the cell phone/charger. Charging will take a long time for a long time, usually at night. But in China's power grid, voltage is relatively high, at night in many parts of the voltage may be unstable. As mentioned earlier, lithium battery is fragile. Compared with nickel, their resistance to charge and discharge fluctuations are much smaller, and nickel can bring extra risk.
