    摘要： The present invention discloses negative electrode for zinc nickel secondary batteries and the fabrication methods. These negative electrodes contain hydrophobic porous conductive granules such as carbon black granules with a hydrophobic material adsorbed. The fabrication methods for these negative electrodes include the following steps: adding a hydrophobic material to conductive porous granules such as granules in an aqueous solution; stirring said aqueous solution with said conductive porous granules and said hydrophobic material; fabricating the active material with said aqueous solution with said conductive porous granules and said hydrophobic material; and forming said negative electrode with said active material. Batteries with negative electrodes that are embodiments of this invention or are fabricated by the method of this invention are efficient in the recombination of oxygen at the electrodes during charging have low internal pressure, and are not subjected to electrolyte leakage.

    摘要： The present invention discloses enhanced separators for storage batteries with zinc negative electrodes. These enhanced separators include a separator layer and one or more resistive layers on said separator layer. The dimensions of the one or more resistive layers are less than or equal to that of the separator layer. Portions of the separator layer can also be treated with a PTFE suspension to increase the resistance at those portions. For storage batteries where the resistance along two edges of the separator layer has to be larger then the center, the enhanced separator include said resistive layers where each layer includes two independent parts positioned along the two edges of the separator layer. The edge portions of the separator layer can also be treated with a PTFE suspension. Using these enhanced separators in storage batteries with zinc negative electrodes can increase the capacity and prolong the life of the batteries. These enhanced separators are also simple, easy to manufacture, and low in cost.
