Ｚｎ、Ｎｂ、Ｓ为原料，在１０２５℃，４．０×１０９Ｐａ高压下进行固相反应，生成物“ＺｎｘＮｂＳ３”为ＮｂＳ３和ＺｎＳ的多晶混合物。ＮｂＳ３属单斜晶系，ＺｎＳ属六方晶系。研究分散的ＺｎＳ第二相粒子对“ＺｎｘＮｂＳ３”电导性能影响。混合相导电激活能下降，离子电导率增大。以“ＺｎｘＮｂＳ３”混合相为阴极主要成分组装了Ｚｎ固态电池，电池性能比以ＮｂＳ３为阴极主要成分的Ｚｎ固态电池有所提高。
Zn, Nb and S as raw materials, solid phase reaction was carried out at 1,025 ° C under a pressure of 4.0 × 109Pa to form a polycrystalline mixture of “ZnxNbS3” consisting of NbS3 and ZnS. NbS3 is a monoclinic system, ZnS is a hexagonal system. The influence of dispersed ZnS second phase particles on the conductivity of “ZnxNbS3” was studied. The conductivity of mixed phase decreases and the ionic conductivity increases. Zn solid-state battery was assembled with ZnxNbS3 mixed phase as the main component of the cathode, and the performance of the battery was improved compared with Zn solid-state battery with NbS3 as the main component of the cathode.
