CHEMICAL SOURCE OF ELECTRIC ENERGY Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: invention relates to manufacture of alkaline chemical sources of electric energy with zinc anode. Composition of anode is injected with mixture of two copolymers as additive. One of them is based on polyol and ethylene oxide with molecular mass 230-1100 arbitrary units with mole proportion of monomers 1:3-1: 19 containing hydroxyl or alkyl as end groups chosen from series of methyl, ethyl, propyl. The other copolymer is based on polyol and ethylene oxide with molecular mass 230-6100 arbitrary units with mole proportion of monomers 1:4- 1:22 containing hydroxyl, alkyl or aryl substituent selected from group including hydroxyl, methyl, ethyl, propyl, phenyl, benzyl, cresyl, toluyl, benzolsulfoacid, salicylic acid. Polyol is chosen from group containing glycols, glycerines, pentherithrit or sorbit with following proportion of components, per cent by mass: zinc 98.18-99.69, mercury compound (in terms of oxide) 0.009-0.550; first copolymer 0.114-1.248; second copolymer 0.011-0.780. EFFECT: increased operational properties. 1 tbl
