Zinc-bromine storage battery for electric vehicles
Abstract
Constructional features, performance and life testing of a prototype zinc-bromine storage battery for an electric city vehicle are described. Designed, built and experimented with in our laboratories with promising results, this battery makes use of thin bipolar titanium electrodes, zinc being deposited on the negative and bromine on the positive side. Titanium passivation is prevented by coating the positive side of the bipolar titanium electrode with conductive ceramic oxides. An aqueous electrolyte is used consisting of a concentrated solution of zinc bromide acidified to pH 1.5-2 with bromic acid, and circulated through each cell.
