In article number 2003902, Wangwang Xu, Changtong Mei, Qinglin Wu and co‐workers show that the robust tunnel structure of a vanadium dioxide cathode and the network of a polyacrylamide‐chitin nanofiber hydrogel electrolyte provide efficient pathways for ion diffusion, leading to superior electrochemical performance of the corresponding solid‐state zinc ion batteries (ssZIBs). The flexible ssZIBs demonstrate excellent self‐rechargeability and superior reusability, which provides a facile route to portable self‐powered systems.
