Abstract

Interfaces between LiCoO₂ and sulfide solid electrolytes were modified in order to enhance the high-rate capability of solid-state lithium batteries. Thin films of oxide solid electrolytes, Li₄Ti₅O₁₂, LiNbO₃, and LiTaO₃, were interposed at the interfaces as buffer layers. Changes in the high-rate performance upon heat treatment revealed that the buffer layer should be formed at low temperature to avoid thermal diffusion of the elements. Buffer layers of LiNbO₃ and LiTaO₃ can be formed at low temperature for the interfacial modification, because they show high ionic conduction in their amorphous states, and so are more effective than Li₄Ti₅O₁₂ for high-power densities.
