Energy Storage is critical for grid modernization and electrification of transportation infrastructure. For transportation, development of high energy and low cost battery technologies with improved safety is a high priority. For grid scale energy storage, the application markets are complicated. Both the capital cost and live cycle cost of the technologies still need to be significantly reduced.<br/> <br/>This presentation will discuss challenges for high energy batteries, including challenges for the Battery500 Consortium, with an emphasis on progresses in the fundamental understanding of full battery reaction mechanisms and materials issues in lithium battery systems. Currently lithium ion batteries are approaching its maximum energy density, but the cost is continuing to decrease. Replacing the current electrode materials with silicon anode and lithium metal could significantly increase the energy density and reduce the cost, but requires breakthroughs in carefully controlling the electrochemical reactions in the whole battery system, particularly the interfacial reactions on both the cathode and anode sides. This talk will also discuss other technologies including redox flow, Na-ion and Li-S batteries. These emerging technologies use low cost and abundant materials and are attractive for large scale applications. <br/>
