Description

Conventional Li ion batteries have a number of limitations that prevents them from becoming the energy storage media for electric (EV) and hybrid electric vehicles (HEV). Many of these limitations could be ultimately traced to properties and limitations of the liquid organic electrolytes used in the conventional Li ion batteries. Successful removal of the limitations is a prerequisite for successful practical application of lithium batteries as a high energy storage medium such as it is required for electric vehicles (EV). We propose to fabricate novel high energy and high power all solid state lithium batteries whose performance will match and exceed EV/HEV requirements. At the core of the proposed batteries is a new fast inorganic solid electrolyte whose outstanding properties facilitate overcoming the limitations of conventional Li ion batteries. Commercial interest in batteries with high capacity that are additionally safe when applied is well established. The ever-present gadgets of modern life remain constrained by the availability of power to quench the thirst of power hungry electronics. The development of safe and high capacity lithium batteries is of prime importance to the development of successful electric vehicles, and hence, improved lithium battery technology should have a significant impact on the nations carbon footprint and reliance on foreign oil.
