A tripartite synergistic optimization strategy for zinc-iodine batteries.

ABSTRACT: The energy industry has taken notice of zinc-iodine (Zn-I₂) batteries for their high safety, low cost, and attractive energy density. However, the shuttling of I₃^- by-products at cathode electrode and dendrite issues at Zn metal anode result in short cycle lifespan. Here, a tripartite synergistic optimization strategy is proposed, involving a MXene cathode host, a n-butanol electrolyte additive, and the in-situ solid electrolyte interface (SEI) protection. The MXene possesses catalytic ability to enhance the reaction kinetics and reduce I₃^- by-products. Meanwhile, the partially dissolved n-butanol additive can work synergistically with MXene to inhibit the shuttling of I₃^-. Besides, the n-butanol and I^-
