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 lags far behind the organic alkali metal- (e.g. Li-, Na- and K-) ion batteries. Herein, we first analyze the challenges that specifically faced by organic MMIBs and then discuss the strategies that could probably solve such challenges. As a special challenge that organic MMIBs are facing, the charge storage mechanism is particularly underlined to deep understand the structure-property relationships for guiding the future design of high-performance organic electrodes for MMIBs. And the perspectives are thereby elaborated in the following with the outlook of practical applications of organic MMIBs.
