Abstract
All solid state batteries are attracting interests as next generation energy storage devices. However, little is known on interfaces between active materials and solid electrolytes, which may affect performance of the devices. In this study, interfacial phenomena between electrodes and solid electrolytes of all solid state batteries were investigated by using nano-composites of Li 2SiO 3-TiO 2, Li 2SiO 3-LiTiO 2, and Li 2SiO 3-FePO 4. Studies on ionic conductivity of these composites revealed lithium ion transfer across the interfaces without electric field, which depended on electrode potentials. For Li 2SiO 3-TiO 2, conductivity of the composites was enhanced ...
