Short circuit in battery
Is the main cause of battery explosion
Generally, there are three situations: mechanical loss of control
Indicates that the battery has been strongly squeezed or punctured
cause damage
destroyed the diaphragm
Short-circuit the positive and negative plates
Second electrochemical runaway
Refers to the formation of gold branches by lithium ions on the negative plate
thus causing damage to the diaphragm
causing internal short circuit
Like the battery quality is not good
Non-compliant fast charging and overcharging
will lead to electrochemical loss of control
Three temperature out of control
Refers to the charging and discharging of lithium ions in a high temperature environment
Other reactions occur between the positive and negative electrode sheets and the electrolyte
Release oxygen and extra heat
causing the diaphragm to dissolve
thus forming a large-area short circuit
