    • An alkaline cell having an anode mixture comprising zinc particles, aqueous alkaline electrolyte, and molecular sieve additive. The cathode preferably comprises manganese dioxide. The cell may be cylindrical or any other shape or size. The molecular sieve additive preferably comprises a crystalline aluminosilicate material which is in at least a partially dehydrated state before admixture with the aqueous electrolyte, preferably potassium hydroxide. The aluminosilicate crystalline structure has average pore size between about 3 and 25 Angstrom. The addition of the molecular sieves to the zinc anode improves the cell's discharge capacity and service life. The molecular sieves preferably comprises between about 0.07 and 0.7 percent by weight of the anode mixture.
    • 具有阳极混合物的碱性电池,其包含锌颗粒,碱性电解质水溶液和分子筛添加剂。 阴极优选包含二氧化锰。 电池可以是圆柱形或任何其它形状或尺寸。 分子筛添加剂优选包含在与含水电解质混合之前至少部分脱水状态的结晶硅铝酸盐材料,优选氢氧化钾。 铝硅酸盐晶体结构具有约3至25埃的平均孔径。 向锌阳极添加分子筛可提高电池的放电容量和使用寿命。 分子筛优选占阳极混合物重量的约0.07%至0.7%。
