ELECTROLYTE FOR ZINC-BROMINE STORAGE BATTERIES

摘要

The growth of dendrites in storage batteries, having a negative electrolyte containing zinc bromide, is inhibited by including in the electrolyte a brominecomplexing agent (methyl ethyl morpholinium bromide or methyl ethyl pyrrolidinium bromide) and a dendrite inhibitor which is a quaternary morpholinium, pyridinium, pyrrolidinium or amminium salt containing at least one methyl, butyl, decyl, dodecyl or benzyl group. The electrolyte may optionally also contain bivalent tin or lead ions and an electrical conductivity improver.
