摘要： The invention relates to a cylindrical AAA alkaline dry battery including: a positive terminal protruding from one end face of the alkaline dry battery; a negative terminal protruding from the other end face; and an external label covering the alkaline dry battery. The diameter Dp (mm) and protruding height Hp (mm) of the positive terminal and the diameter Dn (mm) and protruding height Hn (mm) of the negative terminal satisfy the relation (1): 2.5≦Dn−Dp≦4.1 (1), and the relation (2): 0.8≦Hp−Hn≦1.1 (2). This permits easy and reliable identification of the polarities of the terminals, making it possible to provide a cylindrical AAA alkaline dry battery which is unlikely to be installed reversely.

摘要： An electrochemical cell with a blended zinc powder is disclosed. The blended zinc powder includes selected portions of a first zinc powder and a second zinc powder. In a preferred embodiment, the first and second powders are divided into groups based on ranges in their particle size distribution. Particle characteristics such as roughness and elongation are used to selected groups of both powders that are combined to produce the blended zinc powder. The blended zinc powders enable battery manufacturers to maximize the cell's run time while minimizing the cost of the zinc.
