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 fiber which contains silica and alumina. Preferably, the composition of the inorganic fiber is in the range of 80% to 99% alumina, and 1% to 20% silica. Typically, the zinc electrode will further comprise an inorganic fiber 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. |
