Abstract
In a reserve battery comprising a plurality of cells, each of which contains plates of different materials immersed in an electrolyte, wherein uniform filling of the cells with electrolyte is ensured by equalizing apertures formed in the partitions between adjacent cells, the electrolyte contains about 0.05 to 5.0 percent by weight of an organic levelling agent as used in electro-plating whereby the rate of growth of filamentary accretions extending from the electrodes is reduced.
Claims4
As a reserve battery electrolyte, an electrolyte solution selected from the group consisting of perchloric acid, fluoboric acid, fluorsilicic acid and nitric acid, said solution having added thereto as an accretion growth inhibitor, from 0.05 to 5.0 weight percent of a levelling agent selected from the group consisting of gelatine, peptone, phenol, hydroquinone, 1,4 naphthoquinone, 1-naphthol-4-hydroxy anthroquinone, 1-amino-1-naphthol-3-sulphonic acid, eugenol, lignin-sulphuric acids, dimethyl aniline, dibenzene sulphonamide, allantoin, resorcinal, coumarin, 1,4 naphthol sulphonic acid, urea and glycine.
