Abstract

The invention provides a miniaturized overload activated thermal battery and a preparation method thereof, comprising a battery case, wherein a battery cover is arranged on the battery case; an overload activator is arranged on the battery cover. The overload activator is installed at the bottom of the battery cover through a rotational connection mode. A battery stack is arranged below the battery cover. The battery stack is connected with the battery cover through a fixing piece; a light device is also arranged in that battery stack. The overload activator is threadably mounted in the centerof the bottom of the battery lid to make full use of the stack space. The invention realizes the special requirement of miniaturized weapon equipment for small volume and large capacity overload activated thermal battery. The specific energy of this kind of thermal battery can be increased by more than 30%, and the thermal battery can be more widely used in miniaturized weapons and equipment.
