A family of Li-ion battery cathode materials and methods of synthesizing the materials. The cathode material is a defective crystalline lithium transition metal phosphate of a specific chemical form. The material can be synthesized in air, eliminating the need for a furnace having an inert gas atmosphere. Excellent cycling behavior and charge/discharge rate capabilities are observed in batteries utilizing the cathode materials.
