    • Methods of manufacturing a rechargeable power cell are described. Methods include providing a slurry, paste, or dry mixture of negative electrode materials having low toxicity and including dispersants to prevent the agglomeration of particles that may adversely affect the performance of power cells. The methods utilize semi-permeable sheets to separate the electrodes and minimize formation of dendrites; and further provide electrode specific electrolyte to achieve efficient electrochemistry and to further discourage dendritic growth in the cell. The negative electrode materials may be comprised of zinc and zinc compounds. Zinc and zinc compounds are notably less toxic than the cadmium used in nickel cadmium batteries. The described methods may utilize some production techniques employed in existing NiCad production lines. Thus, the methods described will find particular use in an already well-defined and mature manufacturing base.
    • 描述了可再充电电池的制造方法。 方法包括提供具有低毒性并包括分散剂的负极材料的浆料,糊剂或干混合物,以防止可能不利地影响动力单元性能的颗粒的聚集。 该方法利用半透膜分离电极并最小化枝晶的形成; 并进一步提供电极特异性电解质以实现有效的电化学和进一步阻止细胞中的树突生长。 负极材料可以由锌和锌化合物组成。 锌和锌化合物的毒性明显低于镍镉电池中使用的镉。 所描述的方法可以利用现有NiCad生产线中使用的一些生产技术。 因此,所描述的方法将在已经定义明确且成熟的制造基地中得到特别的应用。

    • A nickel-zinc galvanic cell is provided, having a zinc oxide negative electrode, a nickel oxide positive electrode, and an alkaline electrolyte. Chemical additives are placed in each of the negative and positive electrodes. The positive nickel hydroxide electrode contains a mixture of cobalt oxide contained within a nickel oxide matrix in the range of about 1% to 10%, and cobalt metal in the range of about 1% to 10%, by weight. The negative zinc oxide electrode may contain oxides other than the oxide of zinc, which have redox potentials which are negative of −0.73 volts. Also, the metal oxide additives to the negative zinc oxide electrode are such as to inhibit release of soluble cobalt from the nickel oxide negative electrode prior to a formation charge being applied to the electrochemical cell.
    • 提供了具有氧化锌负极,氧化镍正极和碱性电解质的镍锌原电池。 化学添加剂被放置在负极和正极中的每一个中。 正极氢氧化镍电极含有氧化镍基质中含有约1%至10%范围内的钴氧化物和约1%至10%重量的钴金属的混合物。 负极氧化锌电极可以含有除氧化锌以外的氧化物,其氧化还原电位为-0.73伏负。 此外,负电荷氧化锌电极的金属氧化物添加剂在施加到电化学电池之前,可以抑制可溶性钴从氧化镍负极的释放。

Chemical additives are placed in each of the negative and positive electrodes. The positive nickel hydroxide electrode contains a mixture of co-precipitated cobalt oxide in the range of 1% to 10%, and freely added, finely divided cobalt metal in the range of 1% to 5%, by weight.
