　　Composition of mobile phone lithium battery

　　:Lithium-ion batteries are composed of plastic cover, lithium-ion core, battery protection plate and repairable safety. Some of them will continue to be equipped with NTC identification resistors, vibration motors, current and other components. The role of each component can be divided into: The lithium-ion core is the power source of the rechargeable battery. The battery protection board displays overcharge, discharge and overcurrent protection for the rechargeable battery. It can be repaired into positive thermistor and negative thermistor, and the positive thermistor has the function of high temperature maintenance of rechargeable battery. Identify the resistor to identify the primary battery. Non-primary batteries cannot be used. Testing of mobile phone lithium batteries

　　In order to ensure the characteristics and application safety of mobile phone lithium batteries, rechargeable batteries are generally tested during the process. The testing generally includes shape and function testing to determine whether the quality of mobile phone lithium batteries is intact. The battery test set - high current spring microneedle beauty touch set must be used during the entire test process. Since mobile phone lithium battery testing requires too much transmission current, the high-current spring microneedle beauty touch group has a very effective solution for mobile phone lithium battery testing, and its characteristics can be trusted. During the entire current transmission process, the overcurrent can reach up to 50a. The current transmission in the range of 1-50a is very stable and maintains a good connection. The average life of the high-current spring microneedle beauty set is more than 20 weeks, which can meet the requirements of high-frequency testing of mobile phone lithium batteries. Using different head shapes to contact different test cases in the detection of spring microneedle beauty touch groups is beneficial to current transmission and data signals.

　　Capacity of mobile phone lithium battery The battery capacity is divided into short circuit capacity and specific capacity. Short circuit capacity is the minimum amount of charge that should be released under certain charging and emission standards. The specific capacity of a mobile lithium battery is the specific amount of charge released under certain charging and discharging standards. Rechargeable batteries of unlikely sizes, cannot be used for exchange, will have leakage or zero operating voltage conditions. Differences in the capacity of the lithium-ion batteries on your phone can cause the battery to charge or not charge. Mobile Lithium Battery Rechargeable Lithium-ion batteries are damaged by the number of charges and discharges and temperature. The center of rechargeable battery management is the battery grade/lithium battery electrolyte. The chemical changes in the battery grade/lithium battery electrolyte are related to the operating temperature, false temperature drop, and subsequent decrease in battery level reflectivity. When the temperature is higher, the battery power increases, and the transmission temperature of electrolysis will increase. Once the transmission temperature decreases, the charging characteristics of the battery will be damaged. The chemical reaction balance of lithium-ion batteries is disrupted by excessive temperatures in the battery. After a period of time of mobile phone lithium battery life, the lithium-ion battery will find that the battery life is reduced and must be charged frequently. The reasons for this situation will be 1. The type of charger and rechargeable battery do not match, and the application is not product charger 2. The experience and overcharge and discharge behavior during the use of rechargeable batteries (that is, after the rechargeable battery is fully charged, the battery capacity will indicate a low capacity and the behavior will continue to be used) 3. Frequent side charging Looking sideways at the phone. This element will harm the life of mobile phone lithium batteries. For a long time, rechargeable batteries have not been able to save power. Needless to say, they will continue to rise as they become more durable. If the lithium-ion battery is not good for long-term use, it is best to freeze-dry it in a place to prevent sunlight.
