Exploring Novel Nano-composite Strong Ionic Compounds for Lithium Storage

Abstract

Strong electron localization in ionic crystal has hindered their application to the electrochemical devices as lithium batteries. However, recent advances in nano-composite formation with conductive phase have opened the door to examine hitherto-unexplored materials as electrode applications. Lithium iron phosphate, LiFePO₄ is a good example of this. As a result of some screening of fluolides, oxyfluolides, and silicates, Li₂MnSiO₄ and Li₂CoSiO₄ were found to show electrochemical activities for reversible lithium intercalation.
