Challenges and Perspectives of Organic Multivalent Metal‐Ion Batteries

Abstract Rechargeable organic multivalent metal‐ion batteries (MMIBs) have attracted a surge of interest as promising alternatives for large‐scale energy storage applications because they can combine the advantages of both organic electrodes and multivalent metal‐ion batteries. However, the development of organic MMIBs is hampered by many factors, which mean they lag far behind organic alkali‐metal‐ (e.g., Li‐, Na‐, and K‐) ion batteries. Herein, the challenges that are specifically faced by organic MMIBs are analyzed and the strategies that can probably solve such challenges are then discussed. As a special challenge that organic MMIBs are facing, the charge‐storage mechanism is particularly underlined to deeply understand the structure–property relationships for guiding the future design of high‐performance organic electrodes for MMIBs. The perspectives are thereby elaborated in this review with the outlook of practical applications of organic MMIBs.
