Lithium battery safety challenges and countermeasures

As the main energy source for modern electronic devices and electric vehicles, Lithium Batteries bring convenience to people, but they also face safety risks. This article will discuss the possible safety issues of lithium batteries under conditions such as overcharge, overdischarge, and high temperature, and introduce the application of various safety measures and technologies.

Potential safety hazards:

Overcharging: If a Lithium Battery is overcharged during charging, it will cause excessive gas to be produced inside the battery and increase the internal pressure of the battery, which may cause serious safety issues such as explosion or fire.
Over-discharge: If a lithium battery is over-discharged during discharge, it will cause damage to the internal structure of the battery, which may lead to reduced battery performance or even damage, or even cause safety accidents such as fires and explosions.
High-temperature environment: Lithium batteries are particularly prone to accidents such as spontaneous combustion and explosion in high-temperature environments, because high temperatures will accelerate the volatilization of the electrolyte, increase the pressure on the battery, and cause the battery to lose control.

Lithium battery safety challenges and countermeasures

Safety measures and technical applications:

Battery Management System (BMS): BMS is an intelligent system that can monitor the voltage, current, temperature and other parameters of the battery, detect abnormal conditions of the battery in a timely manner, and take corresponding measures to ensure the safe operation of the battery.
Temperature control technology: By embedding a temperature sensor in the lithium battery, the temperature changes of the battery are monitored in a timely manner. Once the temperature is too high, the charging rate can be automatically reduced or charging stopped to avoid safety hazards caused by high temperature.
Safety valve design: Designing a safety valve in a lithium battery can release gas when the internal pressure is too high, reduce the internal pressure of the battery, and reduce the risk of explosion.
Material improvement: Continuously improve the electrolyte, positive and negative electrode materials, etc. to improve the high temperature resistance and safety of the battery and reduce the probability of battery accidents.
