Abstract

PURPOSE:To increase heat insulation effect by forming a vacuum layer within a battery case in a thermal battery which generates the function of a battery by melting an electrolyte with an inner heating material. CONSTITUTION:In a thermal battery which generates the function of a battery by melting an electrolyte stored in a solid state with an inner heating material when the battery is used, a vacuum layer is formed within a battery case. Battery components 1 are surrounded with a separator wall 2 comprising heat insulating material and electrical insulating material and a vacuum layer 3 is formed between the separating wall 2 and a case 4, then they are sealed with a cover 5 having hermetically sealed terminals. Heat insulating effect on the side and in the bottom of the battery is increased and drop in inner temperature is decreased. Discharge duration of the battery is increased.
