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 2 O 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 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.
