A zinc electrode is provided for use in electrochemical cells having an alkaline electrolyte and high cycle life. The zinc electrode comprises a mixture of zinc oxide together with an inorganic fibre which contains silica and alumina. Preferably, the composition of the inorganic fibre is in the range of 80 % to 99 % alumina, and 1 % to 20 % silica. Typically, the zinc electrode will further comprise an inorganic fibre additive in the range of 2 % to 15 % by weight of the zinc oxide electrode. Also, the zinc electrode will typically further include 2 % up to 10 % of bismuth oxide. |
