BATTERY OF ELEMENTS OF THERMAL CHEMICAL SOURCES OF CURRENT Russian patent published in 2016 - IPC H01M2/02 

FIELD: electricity.

SUBSTANCE: battery comprises an inner and an outer tight shells with a cavity between them and two layers of heat insulation, which create the body, where an assembly is located from electrochemical elements alternating with heating elements. The assembly is electrically connected to the first and second outputs of the battery, the first layer of heat insulation is located between the assembly of the elements and the inner shell, and the second one - in the cavity between the shells. The body of the battery is equipped with an additional resistive heating element and a controlled switchboard. The resistive heating element is located between the inner shell and the second layer of heat insulation, outputs of the resistive heating elements are electrically connected to the outputs of the battery, and one of outputs of the resistive heating element is connected to one of outputs of the battery via the switchboard.

EFFECT: provision of reliability of battery operation for the time of operation for more than an hour.
