    摘要： A conductive agent for use in alkaline storage batteries in accordance with one aspect of the present invention contains 0.1 to 10% by weight sodium. This sodium content results from cobalt or a cobalt compound, to which an aqueous solution of sodium hydroxide is added and heated to 50 to 200.degree. C. A non-sintered nickel electrode for use in alkaline storage batteries is also proposed. In this electrode, the aforesaid conductive agent in accordance with the present invention is added to a pulverulent active material consisting of grains of nickel hydroxide or grains mainly constituted by nickel hydroxide such that 1 to 20 parts by weight of the conductive agent is added to 100 parts by weight nickel hydroxide contained in the pulverulent active material. Another non-sintered nickel electrode for use in alkaline storage batteries is also proposed. In this electrode, an active material takes the form of composite particles consisting of grains of nickel hydroxide or grains mainly constituted by nickel hydroxide, each of which has a surface formed with an electric conduction layer consisting of a cobalt compound containing 0.1 to 10% by weight sodium.

    摘要： The present electrode is fabricated by coating a conductive substrate with a paste including a hydrogen-absorbing alloy, a binder and a carbon material and sintering the conductive substrate coated with the paste under vacuum or in an atmosphere of a non-oxidizing gas. In this electrode, the carbon material works as a reducing agent so as to suppress oxidation of the hydrogen-absorbing alloy during the sintering, and therefore, the electrode exhibits large oxygen absorbing power in over-charge. Furthermore, the present battery uses, as a negative electrode, the sintered hydrogen-absorbing alloy electrode exhibiting large oxygen absorbing power in over-charge, and hence attains high reliability because increase of the pressure within the battery is minimal.

    摘要翻译： 本发明的电极通过用包含吸氢合金，粘合剂和碳材料的糊剂涂覆导电性基材来制造，并且在真空下或非氧化性气体气氛下烧结涂布有糊剂的导电性基材。 在该电极中，碳材料作为还原剂起作用，以抑制烧结时的吸氢合金的氧化，因此，电极在过充电中表现出较大的氧吸收能力。 此外，本发明的电池使用在过充电中表现出大的氧吸收能力的烧结储氢合金电极作为负极，因此由于电池内的压力增加最小，因此获得高的可靠性。
