内容記述 | 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 by addition of TiO 2 and well explained by space charge layer model. With LiTiO 2 which shows lower electrode potential, the conductivity was deteriorated due to decrease in vacancies in Li 2SiO 3. At the interface of Li 2SiO 3-FePO 4, a lot of Li ions in Li 2SiO 3 are trapped at the interface or maybe are inserted into FePO 4, resulting in many vacancies in Li 2SiO 3 and lattice distortion. The results show the ionic conduction at the interface is strongly affected by the electrode potential and the importance of design of interfaces of all solid state batteries is pointed out. | |||||
