1. A cathode material for lithium ion batteries, the cathode material comprising:
carbon coated nanoporous lithium vanadium fluorophosphate (c-nLVPF) having a templated pore structure;
wherein the cathode material is synthesized using a combination of a fluoropolymer and polymethyl methacrylate (PMMA) colloids that provide a fluorine source, an oxygen scavenger, and a template material for forming the pore structure in the cathode material.
