摘　　要：以高温处理氯化镍作为热电池的正极材料制备热电池;用溶解理论解释了电池单体材料溢流现象,解决了电池的安全性问题;摸索了与之匹配的制备高比能量热电池所需电解质与负极材料,确定电解质为全锂电解质,负极为LiB合金;用浓差极化解释了氯化镍电池的电压起伏成因。所制备的氯化镍电池的单体电压比以二硫化钴为正极的电池单体电压高25%。与全锂电解质和LiB合金匹配制备的样品电池,比能量达到84Wh/kg。The thermal battery was prepared with high temperature-produced NiCl2 as the cathode. The flooding of the liquid electrolyte was explained by solution theory, which solved the safety problem of the battery. The electrolyte and anode material matching the high energy-density thermal battery were studied, and then LiCl-LiBr-LiF and LiB alloy were determined as the electrolyte and the anode material. The fluctuation of operating voltage is caused by concentration polarization. The voltage of battery with NiCl2 as the cathode is 25% higher than the battery with CoS2 as the cathode. The energy-density of the thermal battery sample with LiCl-LiBr-LiF as the electrolyte, LiB alloy as the anode and NiCl2 as the cathode can reach 84 Wh/Kg.
