  • Rechargeable alkaline silver-zinc cell with improved negative electrode
    Patent number: 5773176
    Abstract: Substantial improvements to the cycle life of silverzinc cells were obtained by the addition of small amounts of bismuth oxide (Bi.sub.2 O.sub.3) to the negative zinc electrode, in conjunction with cadmium oxide (CdO) and lead oxide (PbO). These improvements, which can be extended to other zinc-based alkaline batteries, especially nickel-zinc and zinc-air, can also be realized in conjunction with other metal oxides and hydroxides, particularly indium hydroxide ?In(OH).sub.3 !, which, like Bi.sub.2 O.sub.3, has the additional advantage of being non-toxic.
