There is a need to develop higher gravimetric and volumetric energy density batteries to power the next generation of consumer electronics and automobiles of the future. To achieve this goal there needs to be major advancements the electrolyte used to transfer lithium ions between the anode/cathode during charge/discharge of a lithium-ion battery. The focus of this project is to develop a novel composite electrolyte that can extend the cycle life of batteries and operate under harsh conditions above and below room temperature. The electrolyte we developed consists of a lithium closoborate salt (Li2B12H12) infused into a porous matrix. Lithium-ion batteries fabricated utilizing this composite electrolyte showed excellent cycle stability at fast charge/discharge rates and the ability to operate above and below room temperature. We also demonstrated that the batteries could power an array of LEDs at extreme temperatures.
