Redox-active metal-centered oxalato phosphate open framework cathode materials for lithium ion batteries

Abstract

MOP(OF) up the lithium: Metal organic-phosphate open framework materials, for example K 2.5[(VO) 2(HPO 4) 1.5(PO 4) 0.5(C 2O 4)] (see scheme), are investigated as hybrid cathode materials for lithium ion batteries. The redox-active metal center, robustness, available two-dimensional migration pathways in the abplane, and cavities along the caxis for the migration of the alkali metal ions allow the rapid insertion and extraction of alkali metal ions.
