Developing Robust all-Solid-State Li Battery with a Ceramic Electrolyte and Interfacially Engineered Lithium Metal Anode

The objective of the proposed project is to develop the next generation of the low cost, high energy and high power solid state rechargeable lithium battery using a low cost enabling solid state electrolyte and protected lithium metal electrode developed by University of California in San Diego for use in the plug-in hybrid vehicle and electric vehicle. The advantages of the proposed solid state rechargeable lithium battery includes low cost, high energy density, long life, and thermal stability. The successful development of this proposed low-cost, long life, thermally stable solid state rechargeable lithium battery will result in rechargeable lithium batteries that meet the targets of plug-in hybrid electric vehicle PHEV) and pure electric vehicle EV) in terms of cost, performance and safety requirements. The use of the proposed solid state rechargeable lithium batteries in PHEVs and EVs can significantly contribute to decreasing national oil consumption and improve overall energy efficiency. Further, the proposed solid state battery technology can be readily applied to consumer electronics, military, and space aviation applications, which are all vital to growing the U.S. economy.
