As part of our work in this field, we want to share information on the foundations and current landscape of electrochemical safety. Visit the Initiative Updates tab to dive deeper into these concepts and download resources.
What is Thermal Runaway?
One of the primary risks related to lithium-ion batteries is thermal runaway. Thermal runaway is a phenomenon in which the lithium-ion cell enters an uncontrollable, self-heating state. Thermal runaway can result in extremely high temperatures, violent cell venting, smoke and fire.
What Causes Thermal Runaway?
Faults in a lithium-ion cell, which can be caused by internal failure or external conditions, can result in thermal runaway. One example of internal failure is an internal short circuit caused by defects in the cell that compromise the separator’s integrity.
