The thermodynamically instable nature of lithium metal in liquid electrolytes significantly delays the implementation of the high-energy rechargeable lithium battery technology in electrical vehicles. Although many approaches have been proposed to rescue Li metal anodes, most of the work is performed in small-scale coin cells and tested in the conditions drastically different from the reality. A full knowledge of Li metal activities at the cell level is lacking but extremely critical for the success of developing next-generation rechargeable Li metal batteries.

This webinar will start with discussing the root causes of forming Li metal dendrite in liquid batteries from an electrochemistry point of view and then step into understanding the implications of Li metal dendrites in realistic high-energy pouch cells. The recent progress of Battery500 Consortium will be discussed to highlight the importance of applying electrochemistry principles to understand, identify and address the fundamental challenges in realistic battery technologies.
