What causes a battery accident?

The main causes of these accidents include overheating, short circuit, overcharging, self-heating and mechanical damage. Due to the large number of hazardous accidents involving LIB shown in Table 10, some regulations have been made regarding the transportation and storage of batteries.

Are lithium-ion batteries a good energy storage device?

Lithium-ion batteries are currently the most widely used energy storage devices due to their superior energy density, long lifespan, and high efficiency. However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation.

Why do batteries catch fire when not in use?

In some extreme cases, batteries may catch fire spontaneously when not in use, often due to defects in their manufacturing process. For example, an electric vehicle got self-ignited without traffic accident in 2018, Hubei, China . These defects can accelerate performance deterioration, shorten battery lifespan and compromise battery safety.

What causes battery degradation?

However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation. In extreme cases, these defects may result in severe safety incidents, such as thermal runaway.
