1. A thermal runaway suppression element, adapted for a lithium battery, the thermal runaway suppression element comprising:
a passivation composition supplier, for releasing a metal ion (A) and an aluminum etching ion (B), and wherein the metal ion (A) is selected from a non-lithium alkali metal ion, an alkaline earth metal ion or a combination thereof; and
a polar solution supplier, for releasing a polar solution to carry the metal ion (A) and the aluminum etching ion (B) to an aluminum current collector of the lithium battery, wherein the aluminum current collector is etched through by the aluminum etching ion (B) and an aluminum ion is exchanged, and wherein the metal ion (A) and the aluminum ion are carried by the polar solution inside the lithium battery and seeped into the electrochemical reaction system to terminate an electrochemical reaction.
