Abstract

Metal organic complexes as an artificial solid-electrolyte interface (MOC-SEI) have been generated via in situ coordinative polymerization between Zn²⁺ and organic ligand molecules. Compared to conventional anodes, the MOC-SEI coated anode significantly prolongs the lifespan from 100 h to 1450 h for the Zn||Zn symmetrical cells and increases the reversible capacity up to 160 mA h g^-1 after 1100 cycles for the Zn||V₂O₅ full-cells.
