Lithium battery manufacturers generally have safety protection circuits and various safety devices

List of charging misunderstandings and correct charging methods for mobile phone energy storage lithium battery manufacturers

Nowadays, mobile phones have become our indispensable communication tools, but if you want your mobile phones to be used longer and safer, then you must know the correct charging method of the mobile phone, and also know what are the misunderstandings about the battery charging of the mobile phone.

A mobile phone is a must-have item for modern people. Almost everyone now has a mobile phone, and charging a mobile phone has become a must-do thing for us every day. But do you know what are the misunderstandings of mobile phone battery charging? What is the correct charging method for mobile phones? Let’s take a closer look.


Misunderstandings about mobile phone battery charging

1. The new battery needs several full charge and discharge to activate

Lu Jianguo, director of the comprehensive inspection department of the National Household Appliance Quality Supervision and Inspection Center of China Household Electrical Appliances Research Institute, told reporters that different battery products require different methods to charge and must be used in accordance with the product instructions. Early nickel-cadmium batteries and nickel-metal hydride batteries required similar “activation.” These batteries will produce a “memory effect”. Charging in an incompletely discharged state can easily cause the battery to be overcharged. After a long time, users will feel that the battery will run out quickly. However, most of the batteries used in mobile phones and laptops are lithium-ion batteries. Its initialization process has been completed at the time of manufacture, so it does not need to be activated when it starts to use.

2. Reduce the number of recharges and extend battery life

Generally, the life of a lithium-ion battery can reach hundreds of charge-discharge cycles. The charge-discharge cycle here refers to the process of recharging the battery after it has been used up, rather than plugging in the charger and unplugging it once. Energy storage lithium battery manufacturers have no memory effect and can be charged at any time. In order to reduce the number of recharges, the battery is deliberately used up and then fully charged, which does not extend the battery life, but has a negative impact on the battery life. In addition, if the mobile phone uses automatic shutdown, the energy storage lithium battery manufacturer will cause the internal voltage to be too low due to over-discharge, and may not be able to turn on and charge. Therefore, energy storage lithium battery manufacturers pay attention to “eat less and eat more” in charging, and frequent shallow charge and discharge will help extend their life.

3. Overcharging will cause the battery to explode

Energy storage lithium battery manufacturers generally have safety protection circuits and a variety of safety devices to ensure that the circuit of the battery is automatically cut off in the event of excessive charging and discharging and short-circuit; too high internal pressure of the battery will trigger the decompression of the exhaust device; too high battery temperature Will trigger the hot melt protection device, thereby stopping the electrochemical reaction of the battery. Therefore, unless there is a quality problem, the battery will not explode due to being plugged in for a long time. However, if the battery is not unplugged after being fully charged, the battery will remain fully charged. Although it will not explode, it will speed up the loss of battery capacity.

In addition, there are rumors that answering the phone while the phone is charging will cause an explosion. Experts said that this argument is untenable. If there is such a danger, the product will set up a procedure to not connect to the phone when charging. However, from a health point of view, the wire will limit the user’s range of activities, and making calls while charging may cause the user to stay in one place for a long time and cause excessive muscle tension. Therefore, it is best to unplug the power before talking. When charging, do not cover anything on the battery or put it on the bed to avoid fire.
