SWITCH-MODE CHEMICAL CURRENT SUPPLY Russian patent published in 2006 - IPC H01M6/32 H01M6/10 

FIELD: electrical engineering; stand-by power supplies.

SUBSTANCE: proposed chemical current supply has case with cover, cap, and perforated partition for admitting electrolyte to electrode blocks; case accommodates at least one ampoule holding thionyl chloride based nonaqueous electrolyte and rated quantity of electrode blocks. Ampoule has movable-base bellows mounting disintegrating membrane for displacing this movable base in axial direction toward electrode blocks and layers of alkali metal anode and carbon cathode with porous separator in-between. Mounted within case in center of fixed perforated partition that separates ampoule and electrode block are means for opening ampoule membrane, pressure pulse source for engaging ampoule membrane opening means, disintegrating membrane tightly fixed on ampoule movable base facing the fixed perforated partition of each electrode block. Perforated partition designed to pass electrolyte so that ampoule disintegrating membrane covers inlet of distribution system providing communication between ampoule and electrode units is built in at electrode block entry; all electrode blocks are positioned in parallel with case and pressure pulse source axes; pressure pulse source is pneumatically coupled with ampoule bellows. Ampoule filled with electrolyte communicates with electrode blocks by means of single distribution system. Active system of electrode block is made in the form of compressed anode material structure flatly corrugated along its longitudinal axis with multiple cathode-material plates covered with porous separator bags mounted in corrugation valleys; cathode is made in the form of metal net covered with carbon layer. All electrode blocks are disposed so that their longitudinal and transverse axes are parallel and centers of transverse axes lie on curves symmetrical to center line of source case; their adjacent faces are joined together.

EFFECT: minimized volume at high discharge characteristics.
