Thermal battery principle

A thermal battery is a single-use, thermally activated reserve battery that employs electrical signals, mechanical force, or overload activation to ignite its internal heating system. This process melts the solid molten salt electrolyte between the cathode and anode into a conductive ionic state, thereby enabling the battery to deliver electrical power.
