Molten Salt Etching of V 2 AlC to Fabricate Multifunctional Coating for High‐Performance Zinc‐Iodine Batteries

. The full batteries paired with iodine-loaded porous carbon cathode exhibit an excellent capacity retention of 89.3% after 5000 cycles at 5 C. This work opens a new pathway to modulate the zinc anode interface process, which can also be extended to other aqueous batteries.
