FIELD: electrical engineering; chemical power supplies. SUBSTANCE: current supply has metal case, positive and negative plates, porous propylene separators, electrolyte-penetrable heat-sensing spacers made of heat-resistant porous material and easy- melting substance which are disposed on surfaces of positive plates, and electrolyte. High discharge power characteristics of current supply are attained at the same time retaining its high heat and explosion safety due to fine-pore structure of heat-sensing spacers formed by covering heat- resistant porous backing with thin layer of easy-melting inert material in the form of powder with definite size of particles. EFFECT: enhanced specific characteristics of chemical current supply.
