The Next Generation of Lithium-Ion Batteries: Challenges and Opportunities

Abstract: Although the commercialization of lithium-ion batteries occurred more than two decades ago this versatile technology continues to be actively developed for advanced applications. Clean energy technologies such as wind and solar as well as electric and hybrid electric vehicles all rely on energy storage devices (e.g., Li-ion batteries) for their implementation and success. Argonne National Laboratory is the Nation’s premier energy storage research facility and has been tasked by the Department of Energy to develop advanced battery systems for the next generation, and beyond, of transportation and grid storage technologies. This presentation will discuss the current status of what is believed to be the most promising class of cathode materials to date for transportation applications. If successful, this class of cathodes could greatly enhance battery safety and energy density while lowering overall costs. However, significant barriers to implementation do exist. These barriers will be presented and discussed in terms of recent studies on working electrode materials. Finally, outstanding challenges and opportunities in the field will be presented.
