Failure-Guided Coupling of Interphase and Solvation Chemistry for Durable Aqueous Zn-S Batteries.
Aqueous Zn-S batteries offer high theoretical energy density and intrinsic safety, but iodine-mediated sulfur conversion introduces severe chemical and electrochemical instability at Zn anode. Herein, life-cycle-resolved three-electrode measurements reveal that, although sulfur utilization gradually decreases, the rapi...
