Abstract:

To meet the high-energy requirements that can enable the 40-mile electric drive plug-in hybrid electric vehicle (P-HEVs), long range electric vehicle (EV) and smart grid, it is necessary to develop very high energy and high power cathodes and anodes that, when combined in a battery system, must offer over 5,000 charge-depleting cycles, 15 years of calendar life as well as excellent abuse tolerance. These challenging requirements make it difficult for conventional battery systems to be adopted in P-HEVs and EVs. In this talk, we will first introduce the next generation lithium ion battery that include the Ni rich full gradient cathode [1], a high voltage and nonflammable Fluorinated based electrolyte and Silicon-graphene composite anode including a novel pre-lithiation technology to overcome the irreversible loss of this anode in the first cycle . We will then finish by describing a novel lithium superoxide based on a close battery system that offers at least 3 times the energy density of the state of the art lithium ion battery [2-3] and a SeS system with novel electrolytes that suppress the dissolution of polysulfide species [4].
