    • Methods of manufacturing a rechargeable power cell are described. Methods include providing a slurry or paste 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 NiCad 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.
    • 描述制造可再充电电池的方法。 方法包括提供具有低毒性且包括分散剂的负电极材料的浆料或糊剂以防止可能不利地影响电池性能的颗粒附聚。 该方法利用半渗透性片材来分离电极并使树突的形成最小化; 并进一步提供电极特异性电解质以实现有效的电化学并进一步阻止细胞中的树枝状生长。 负极材料可以由锌和锌化合物组成。 锌和锌化合物的毒性比镍镉电池中使用的镉小得多。 所描述的方法可以利用现有NiCad生产线中采用的一些生产技术。 因此,所描述的方法将在一个已经明确界定和成熟的制造基地中找到特别的用途。
