研究了以硫代LISICON（Li3.25Ge0.25P0.75S4）固体电解质为负极，Chevrel相为阴极的全固态陶瓷锂电池。阴极结构的纳米复合材料降低了界面电阻，并在界面处提供了快速的电荷转移。在Li-Al/SE界面处形成了自组装的固体电解质界面（SEI）相，而在Li-In/SE界面处没有观察到SEI相的形成。SEI相降低了界面电阻，并提供了高的充放电特性。全固态电池表现出1.3C倍率的高电流密度，是未来锂电池系统的有希望的候选者。
All solid-state ceramic lithium battery was studied using a composite anode, the thio-LISICON (Li 3.25 Ge 0.25 P 0.75 S 4 ) solid electrolyte, and the Chevrel phase cathode. The nano-composite of cathode configuration reduced the interfacial resistance and provided fast-charge transfer at the interface. The self-assembled solid-electrolyte interfacial (SEI) phase was formed at the Li-Al/SE interface, while no formation was observed at the Li-In/SE interface. The SEI phase reduced the interfacial resistance and provided high charge-discharge characteristics. The all solid-state cell showed high current density of 1.3C rate and is a promising candidate for future lithium battery system.
