Redox‐Active Metal‐Centered Oxalato Phosphate Open Framework Cathode Materials for Lithium Ion Batteries

MOP(OF) up the lithium: Metal organic–phosphate open framework materials, for example K2.5[(VO)2(HPO4)1.5(PO4)0.5(C2O4)] (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 ab plane, and cavities along the c axis for the migration of the alkali metal ions allow the rapid insertion and extraction of alkali metal ions.
