Microstructure and electrochemical properties of various lithium lanthanum titanate (LLT)/LiCoO_2 assemblies were investigated in order to establish some ways to improve battery performance of all solid-state lithium secondary batteries by controlling the interface microstructure. We have revealed that the battery performance can be drastically improved by introducing very thin amorphous layers at the interface and also by controlling the geometrical configuration of the layered structure of LiCoO_2 through the control of the surface orientation of the crystalline electrolytes.

研究了钛酸镧锂(LLT)/LiCoO_2组件的微观结构和电化学性能，旨在通过控制界面微观结构来提高全固态锂二次电池的电池性能。我们发现，通过在界面处引入极薄的非晶层，以及通过控制晶体电解质的表面取向来控制LiCoO_2层状结构的几何构型，可以大大提高电池的性能。
