AbstractThe paper discusses the challenges associated with the performance of zinc‐ion batteries (ZIBs), such as side reactions that lead to reduced capacity and lifespan. The strategies for mitigating side reactions in ZIBs, including additives, electrolyte‐electrode interface modification, and electrolyte composition optimization, are explored. Combinations of these approaches may be necessary to achieve the best performance for ZIBs. However, continued research is needed to improve the commercial viability of ZIBs. Areas of research requiring attention include the understanding of the mechanisms behind side reactions in ZIBs and the development of cost‐effective and scalable manufacturing processes for ZIBs with available electrolyte. By developing effective strategies for mitigating side reactions, researchers can improve the efficiency and lifespan of ZIBs, making them more competitive with lithium‐ion batteries in various applications, including grid energy storage.
