Possibilities and challenges of cathode materials for Zn-ion batteries

Abstract

The demand for energy storage solutions has been steadily rising with the increasing prevalence of renewable energy sources and the widespread use of portable electronic devices. In this context, zinc-ion batteries (ZIBs) have emerged as a promising alternative to lithium-ion batteries due to their high energy density, cost-effectiveness, and safety advantages. However, the practical application of ZIBs faces limitations due to the lack of suitable cathode materials. This comprehensive review explores the possibilities and challenges associated with various cathode materials suitable for ZIB applications. It also highlights key issues, discusses strategies to overcome these challenges, and provides insights into ongoing prospects in the research of cathode materials. In conclusion, the review offers a perspective on recycling, sustainability, and the efforts of various organizations in the development and promotion of ZIB research for energy storage systems.
