One-dimensional tunnel VO2(B) cathode materials for high-performance aqueous zinc ion batteries: a mini review of recent advances and future perspectives

Aqueous zinc ion batteries (AZIBs) are garnering significant attention as a promising energy storage system owing to their high safety, low cost, and environmental friendliness. Among various cathode materials, one-dimensional (1D) tunnel vanadium-based cathode materials have been extensively studied for their excellent electrochemical performance. In this mini review, we present a summary of recent research progress on 1D tunnel VO₂(B) cathode materials for AZIBs. Specifically, we delve into their crystal structure, morphology, and charge–discharge mechanism, and the impact of various synthesis and modification methods on their morphology and electrochemical performance. Additionally, we provide insights into key strategies employed to enhance the electrochemical performance of VO₂(B). Furthermore, we underscore both the opportunities and challenges in this domain while also discussing the future prospects for the development of 1D tunnel VO₂(B) cathode materials in AZIBs.
