Small lithium-ion batteries, which contain fluorinated low lattice energy lithium salts, are used in computers, cellular phones, and cameras. However, for the mass production of the full size batteries needed for electric vehicles and hybrid electric vehicles (EV/HEV), the electrolytes derived from these salts are far too expensive. Moreover, they are potentially hazardous to the environment. Therefore, this project will identify, develop, and employ novel, cost-effective lithium salts for mass production of full size lithium-ion batteries for EV/HEV applications. Commercial Applications and other Benefits as described by the awardee: The new lithium salts should find a market in the large-scale production of full-size lithium-ion batteries for electric vehicles. They also should be applicable to consumer products such as computers, cell phones, camcorders, and cameras. These materials will meet the requirements at much lower cost than currently available materials.
