Multiple requests from the same IP address are counted as one view. During thermal runaway (TR), lithium-ion batteries (LIBs) produce a large amount of gas, which can cause unimaginable disasters in electric vehicles and electrochemical energy storage systems when the batteries fail and subsequently combust or explode.
LIBs shows gas release behavior and heat generation during the TR process, which stimulates the strong oxidation reaction inside the battery and releases a large amount of gas in a very short period. This causes an impact force . The impact force is the impact energy of the battery released from the kinetic energy.
