Research Institution
65882 Lithium rechargeable batteries have not been widely used in electric or hybrid electric vehicles (EV and HEV) due to the cost, power, and safety limitations of the cathode materials presently used. This project will develop a novel cathode material for lithium rechargeable batteries that is suitable for EV and HEV applications. The new cathode material, consisting of a doped lithiated metal oxide/nitride composite that is capable of reversibly incorporating and releasing lithium, will be inexpensive and have higher charge storage capacity, higher power, and better thermal stability compared to conventional oxide cathode materials. Phase I developed a scaleable synthesis method to produce the low-cost cathode materials. The cathode material was shown to have the combined features of high charge storage capacity, excellent rate capability, and good temperature stability. Phase II will systematically optimize the composition and microstructure of the material, scale up the material synthesis, and demonstrate a power density and a high-temperature performance superior to the conventional oxide cathode. Phase II will also fabricate prototype Li-ion cells for evaluation by potential customers. Commercial Applications and Other Benefits as described by the awardee: The new cathode material should lead to a lithium rechargeable battery for hybrid electric vehicles with significantly improved fuel efficiency and cleanness, and should find broad application in batteries for portable electronics.
