Summary: Magnesium rechargeable batteries are a promising option for large-scale energy storage. Many redox-active polymers have been reported to have good cycling stability in magnesium electrolytes, however, their magnesium storage capacity is lower compared to their lithium counterparts. This study introduces a novel sulfur-linked porous polymer with high material utilization and large pore volume, leading to improved reversible capacity in magnesium electrolytes. The research also identifies a strong correlation between the degree of electrochemical swelling of polymers and their specific capacity in both electrolytes. This work provides important insights for the design of polymer structures for multivalent ion-based energy storage.
