Research Topics


A set of non-flammable electrolytes composed of a lithium salt and a mixture of carbonate and carbonate-like solvents is proposed for Li-ion batteries. Some of these specifically designed solvents, which are not commercially available, will be prepared in a single step from readily available starting materials. These electrolytes are expected to exhibit superior battery performance, including improved safety and wider temperature ranges for operations. This proposal is a combined effort between a growing small business company and a leading academic institution in the area of lithium battery technology. BENEFITS: The developed electrolytes will significantly promote the emerging EV battery market, as well as in other high-power energy storage areas sponsored by the private sector, such as cellular phone and power tool industries.
