The results show that the sample is well dispersed particles with high purity and an average size of about 1 μm. Favorable substances of Ca2 and Sn appear during the cycling of zinc electrode containing CaSn6, Ca2 has continues to react with ZnO to produce calcium zincate, which can highly reduce the dissolvability of anode active materials and greatly improve the cycling performance of zinc electrode. The simulated Ni/Zn battery using CaSn6 and ZnO as the active material of zinc electrode has a high discharge plateau and an excellent cycling ability, and it can retain about 72.6% of initial discharge capacity after 50 charge-discharge cycles.
