METHOD FOR MANUFACTURING LITHIUM CURRENT SUPPLY CASE FROM MULTILAYER FLEXIBLE MATERIAL Russian patent published in 2000 - IPC

FIELD: chemical power supplies. SUBSTANCE: method is used for manufacturing both primary and secondary current supplies with negative lithium plate. Rectangle of three-layer material is folded up with butt-to-butt joined opposite sides to form envelope with thermoplastic polymer inner layer; strap of similar three- layer material is applied to inner side of butt-to-butt joint so that its thermoplastic layer is oriented to that of envelope; ends of strap are bent out and strap is welded to envelope; structural members of current supply are installed in case produced in this way; top and bottom of case are welded together through depth of bent-out ends of welded strap. EFFECT: improved electrochemical characteristics of lithium power supplies. 3 dwg, 1 tbl, 1 ex
