Development of all-solid-state lithium secondary batteries with high safety and reliability is highly demanded. In the present study, phosphorus-based anode materials and sulfur-based cathode materials with high capacity were mechanochemically synthesized. The mechanchemical process was also applied to the formation of a favorable contact among the active materials, a sulfide electrolyte and a conductive additive. It was found that surface modification of high-voltage cathodes with oxide and sulfide thin-films with lithium conductivity was effective in enhancing rate capability and energy density of solid-state batteries.

高度要求开发具有高安全性和可靠性的全稳态锂二级电池。在本研究中，基于磷的阳极材料和高容量的基于硫的阴极材料是机械化学合成的。机械过程也应用于活性材料，硫化物电解质和导电添加剂之间的有利接触形成。发现具有氧化物和硫化物薄膜的高压阴极的表面修饰具有锂电导率有效增强固态电池的速率能力和能量密度。
