PRIMARY CHEMICAL CURRENT SOURCE Russian patent published in 2016 - IPC H01M6/14 H01M6/16 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electrical engineering, particularly, to production of primary chemical current sources (CCS) based on lithium alloy, and can be used as a source of autonomous power supply of onboard equipment and special equipment. Primary chemical current source comprises a body filled with non-aqueous organic electrolyte, in which there is installed an anode containing active material in the form of lithium-containing alloy of the following composition, mol %: lithium - 70-78; tin - 22.0-30.0; bismuth - 0.02-0.7 (alloying additive), with formation of intermetallic lithium-tin phase. Alloy layer is deposited on the current tap-substrate. In the body there is a cathode, containing a mixture of silver oxides, and a separator, which separates the anode and cathode and is made in the form of a microporous polypropylene film. Used as electrolyte, there is a gel-electrolyte containing lithium perchlorate, propylene carbonate, dimethoxyethane, dimethyl formamide, polyacrylonitrile or its copolymers.

EFFECT: reduction of current source self-discharge, higher reliability of its operation with expansion of range of discharge currents is the technical result of this invention.
