The result s show that the cerium compounds consist of Ce 3/ Ce 4 and Ce 2O 3/ CeO 2 , exist in the form of particles and are excellently dist ributed on the zinc powder subst rate. The capacity-loss of the zinc elect rodes is evidently suppressed while the discharge capacity and cycle life can be markedly improved due to the application of the zinc-based composite powder as negative materials of the silver-zinc bat tery. Especially , discharge capacity of 231. 4 mAh g-1 is still achieved at the 50th cycle for the zinc elect rode using the composite powder .

结果表明：由 Ce 3/ Ce 4和 Ce 2O 3/ CeO 2组成的铈化合物以颗粒形式良好地分散在锌粉基体上，用这种锌基复合粉作为模拟锌银电池的负极材料，其锌电极的容量衰减得到明显抑制，放电容量和循环寿命得到显著提高，尤其是其锌电极在 50周期的放电容量仍可达到 231。
