THERMAL BATTERY Russian patent published in 2015 - IPC H01M6/20 H01M6/36 

FIELD: heating.

SUBSTANCE: composite heat insulation made from composite material based on a silicate composition and mica is located outside the unit. In order to equalise thermal conditions of edge electrochemical elements (ECE) between the inner surface of the electrical insulation layer and the side surface of ECE there are plates made from material the specific heat capacity of which is at least 0.11 cal/g·deg installed, and between the insulation and the surface of igniting pyrotechnical belts there are air gaps.

EFFECT: improving operating reliability, excluding the risk of occurrence of short-circuit failures between elements of active masses of electrochemical elements that form a unit of the device.
