Analyze the correct way of charging and discharging lithium batteries

What are the charging methods for mobile phone lithium battery? The composition and composition of a lithium battery The plastic case of mobile phone lithium battery is mainly composed of upper and lower cover, lithium battery, circuit board protection (PCB) and recyclable fuse (polysilicon). Some manufacturers are also equipped with NTC, identification resistor, vibration motor or charging circuit components. The functions of each part are as follows: (1) Lithium battery: supply charge and discharge power. (2) Protect the circuit board (PCB): prevent the battery from overcharging and over-discharging short circuit. (3) Recoverable fuse (PTC): The positive thermistor is used for high temperature protection and is a double protection to protect the circuit board after failure. (4) Recyclable fuse (NTC): Negative thermistor, which senses the internal temperature of the battery for low-temperature protection. (5) Recognition resistance: It is very important to recognize that the primary battery is not an unusable primary battery core, and there are several levels of action, including A cells and B cells. 2. The correct way of charging and discharging the lithium battery Now the mobile phone uses lithium polymer battery, so there is no memory effect problem, and do not activate it. Don’t charge it for more than 12 hours like a nickel battery for the first time, just charge it for about 4 hours. The life of an ion battery is only related to the number of recharges, and a lithium battery can be recharged about 1,000 times. The standby time is related to use. However, the seller stated that the first three charges will take up to 12 hours. How is this? The battery is the source of mobile power and the power of the mobile phone. Without battery power, the mobile phone is a piece of iron, a high-performance and high-capacity battery. Not only does the battery have a long life, the mobile phone can also protect the mobile phone circuit and make the phone Efficient work for a long period of time, on the contrary, unexpected damage may occur on the phone. But for our players, the performance of the battery in the factory has always been qualitative. The size and performance of the battery are determined by the battery itself. In this regard, we cannot change it artificially, but this does not mean that we get the battery. , It can do nothing. This phone uses lithium-ion rechargeable batteries. If the battery runs out, recharge it to supplement the power source. You should not underestimate this part of charging. A good charger and correct charging method can maintain the battery's long standby time and extend the battery's life. More importantly, it can also protect your phone.
