| 摘要 |
According to the invention there are provided negative electrodes for use in zinc based electrochemical cells, comprising as additive incorporated in the electrode, chemically stable electrically conductive fine particles, which are substantially electrically insulated from each other, which create a substantial ohmic drop from the exterior of the electrode to the current collector, said additive being in a form providing a substantially increased effective surface area at a small increase of weight. The preferred form of the additive is foil particles, ribbon, flakes, fibers and platelets. Preferred material of the additive is steel, copper, brass, carbon or graphite, plated with silver, cadmium bismuth or nickel. |
