72090S03-I In order to obviate the deficiencies of currently used electrolytes in lithium rechargeable batteries, there is a compelling need for the development of solvent-free, highly conducting solid polymer electrolytes (SPEs). This project will synthesize a new class of block copolymers and plasticizers, which will be used in the formulation of highly conducting electrolytes for lithium-ion batteries. Phase I will determine the efficacy and commercial prospects of new specifically designed SPEs for use in electric and hybrid electric vehicle (EV/HEV) batteries. This goal will be achieved by preparing the SPEs on a small scale, coupled with thorough analyses of their physical, chemical, thermal, mechanical, and electrochemical properties. Commercial Applications and Other Benefits as described by awardee: SPEs should play a key role in the formulation of next generation lithium-ion batteries and should have a major impact on the future development of EVs/HEVs and a broad range of consumer products (e.g., computers, camcorders, cell phones, cameras, and power tools).
