An aqueous lithium–iodine (Li–I2) cell with solid polymer electrolyte (SPE)-passivated metallic Li is demonstrated. The metallic Li anode is isolated from the aqueous I3−/I− cathode by the SPE and a Li-ion-conductive solid electrolyte layer. The proposed aqueous Li–I2 cells exhibit a discharge potential of approximately 3.4 V versus Li+/Li, stable capacity retention for 50 cycles, and adequate rate capability.
