What is Thermal Abuse of Lithium Batteries?
The definition of Thermal Abuse
Thermal abuse refers to the phenomenon that when using a lithium battery, the internal temperature of the battery is too high, causing the degradation of battery performance and safety performance. This situation may lead to serious consequences such as battery short circuit, explosion, and even fire.
Thermal abuse is usually caused by reasons such as overcharge, overdischarge, external short circuit, excessive heat release, or improper charging and discharging environment. Therefore, when using lithium batteries, it is necessary to follow the correct charging and usage methods to ensure the normal operation and safety of the battery.
How to avoid Thermal Abuse
In order to avoid thermal abuse, the following points should be paid attention to when using lithium batteries:
(1) Avoid excessive charging and discharging
Lithium batteries should not be charged and discharged to a state of too high or too low. Generally, it is recommended to charge and discharge between 20% and 80%. At the same time, choose a suitable charger and charging equipment for charging.
(2) Avoid external short circuit
The positive and negative electrodes of the lithium battery should not be short-circuited or contact conductive substances, such as metal objects.
(3) Avoid excessive heat release
Avoid excessive heat release during use, especially in high temperature environments, and minimize the use of batteries to avoid battery overheating.
(4) Choose a suitable charging and discharging environment
When charging and discharging, you should choose an appropriate temperature environment, and avoid charging and discharging in a high temperature or low temperature environment.
In short, when using lithium batteries, it is necessary to strictly abide by relevant safety regulations and precautions to avoid thermal abuse and ensure the normal operation and safety of the battery.
