All solid-state ceramic lithium battery was studied using a composite anode, the thio-LISICON (Li3.25Ge0.25P0.75S4) 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.
