Abstract

This Small Business Innovation Research Phase I project is to develop and employ novel cost-effective lithium salts for mass production of full size lithium-ion batteries for EV/HEV applications. Small lithium-ion batteries containing fluorinated low lattice energy lithium salts are used in computers, cell phones, cameras, and medical devices. For mass production of full size batteries to be used in electric vehicles and hybrid electric vehicles (EV/HEV), the electrolytes derived from these salts are far too expensive and are potentially hazardous to the environment. In a Li-ion battery, the liquid electrolyte is the second most expensive component after cathode materials. Therefore, there is a great demand for lithium salts that are inexpensive compared to that of the current lithium salts. The availability of such salts will be a major advance in Li-ion battery technology. This project will develop low-cost lithium salts that have excellent electrochemical properties. The broader impact/commercial potential of this project is to introduce to the marketplace new lithium salts for large-scale production of full-size lithium-ion batteries for electric vehicles and consumer products. These environmentally safer and less costly materials will provide improved batteries compared to those currently available. Due to worldwide concerns
