The thermal runaway of lithium motorcycle batteries means that the internal temperature of the battery rises rapidly due to reasons such as overheating, overcharging, short-circuit, or physical damage, resulting in a series of uncontrollable chemical reactions. These reactions release a lot of heat, causing the lithium motorcycle battery to heat up further, which can eventually cause a fire or explosion.
specific process
Initial heat source
A defect inside the battery or an external factor (such as an overcharge or short circuit) causes the local temperature to rise.
Diaphragm melting
When the temperature exceeds the melting point of the diaphragm, the diaphragm fails, and the positive and negative electrodes direct contact, resulting in a large current and greater heat generation.
Electrolyte decomposition
As the temperature continues to rise, the electrolyte begins to decompose, releasing combustible gases such as hydrogen and oxygen.
Fire and explosion
When the gas accumulates to a certain extent or is spontaneously confirmed under high temperatures, the lithium motorcycle battery may catch fire or explode.
