To meet the high-energy requirement that can enable the 40-miles 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 5,000 charge-depleting cycles, 15years 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 different energy storage programs funded by the US Department of Energy including the large DOE investment in Argonne National Laboratory to lead the battery program in the USA. We will then focus on next generation lithium ion battery that include Ni rich full gradient cathode, a high voltage and nonflammable electrolyte and Silicon 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 close battery system that offer at least 3 times the energy density of the state of the Art lithium ion battery.
