High energy density of multivalent glass‐ceramic cathodes for Li‐ion rechargeable cells and as an efficient photocatalyst for organic degradation

Abstract

The tavorite‐structured materials remain unfathomed as positive electrodes in rechargeable batteries. Reasoning of this fact, borate, and silicate‐based tavorites are investigated for utilization in Li‐ion batteries (LIBs) and as a photocatalyst for organic contaminant degradation. The physiochemical, electrochemical, dielectric, and photoelectrochemical properties are analyzed to learn the fact that LiVBO 4 F has resulted in a glass‐ceramic nature owing to the embodiment of boron oxyfluoride glasses. This nature has made them effective as cathodes even under sensitive mode operations compared to their counterpart. Additionally, a multiredox behaviour was witnessed for both the materials, which boosts the specific capacity for LIB system. Besides, LiVSiO 4 F display immense degradation efficiency for tetracycline, an organic contaminant. These materials unveil expedient properties, promising its multiple usage in the field of conversion cum storage devices as photoelectrodes and cathodes in LIBs.
