Abstract
A thermal runaway suppression element, adapted for a lithium battery having an electrochemical reaction system. The thermal runaway suppression element includes: a passivation composition supplier, having a metal ion and an aluminum etching ion; and a polar solution supplier, configured to release a polar solvent to carry the metal ion and the aluminum etching ion to an aluminum current collector of the lithium battery. The aluminum current collector is configured to be etched by the aluminum etching ion to provide an aluminum ion. The metal ion and the aluminum ion are carried by the polar solvent to the electrochemical reaction system to terminate an electrochemical reaction.
