| Research Abstract |
This study have been focused on lithium iron silicates as electrode materials for rechargeable battery due to abundance of mineral resources. It is known that this material suffers from low electronic conductivity, so that special attention has been paid to electronic and ionic conduction mechanism using experimental and computational techniques. The results indicate that arrangement of Li/Fe/Vac changes with state of charge, and the arrangements of ions cause significant effect for ionic conductivity in oxide electrodes.
