To reduce the dependence on imported petroleum and develop a new energy landscape, electrical vehicles powered by lithium ion batteries have attracted intense interests in recent years. While much effort has been expended in increasing the specific energy and energy density at the cell level, research focused on system-level energy density, cost and safety characteristics of advanced batteries has received less attention but is urgently needed to facilitate the process of vehicle electrification. Materials barriers in the areas of safety, cost and robustness of the system need to be overcome for the adoption of electrical vehicles in a broad scale. The intent of this symposium is to provide a forum for scientists worldwide to discuss the strategies to improve the safety attributes and reduce the cost of the battery system. Moreover, this symposium is interested in multifunctional energy storage designs that can increase the final energy density at the vehicle system level.
