Rechargeable lithium ion batteries incorporating liquid or polymer electrolytes are currently the most advanced battery type available on the market. However, the liquid/polymer electrolyte and its interface with the electrodes limits energy density, long-term cycle life, and the rate of charge/discharge capability of these batteries. The removal of these limitations is a prerequisite for lithium batteries to be used successfully as a high-energy storage medium, as required for electric vehicle (EV) applications. This project will develop a solid state electrolyte that solves the problems of the lithium ion batteries while being cost effective and offering manufacturing scalability. Although preliminary tests on the proposed electrolyte material are very encouraging, more research is necessary to demonstrate that it can fulfill all the solid state electrolyte requirements.

Commercial Applications and other Benefits as described by the awardee: The new material should radically transform the world of lithium batteries. The development of batteries with long cycle life, and high energy and power densities should speed the commercialization of electric vehicles.
