A bioimmune mechanism-inspired targeted elimination mechanism on the anode interface for zinc–iodine batteries

full cell, the assembled pouch battery also achieved 1000 cycles without capacity degradation. To further promote the practical applications, the inhibition mechanism of Cy-H additives on full-cell self-discharge was revealed. This work provides new insights for the use of strong acid electrolytes and the elimination of interfacial by-products in aqueous zinc-iodine batteries.
