Abstract

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 LiVBO4 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, LiVSiO4 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. Abstract : Energy conversion and storage devices prevail as an important priority in research. Herein, the materials with the tavorite structures are studied and focussed onto the applications in Li‐ion battery and photocatalysis. The glass‐ceramic nature of LiVBO4 F facilitates the electrochemical properties even at sensitive mode operations, while LiVSiO4 F facilitates photocatalytic tetracycline degradation. These materials can find its application as photoelectrodes as well.
