Abstract

Abstract: Li-ion batteries with a graphite anode and an intercalation cathode have powered the transport in cities, however, it is approaching the physicochemical limitation by the intercalation chemistry. Even when fully developed, today’s Li-ion battery technology will not fulfil the stringent criteria demanded by the fast-expanding electric vehicle market. In order to achieve better batteries with higher energy densities and hence longer driving distances for electric vehicles, more advanced energy storage systems is vital and essential. Here I will show two strategies focusing on either the cathode or anode side to demonstrate two battery systems, Li-O2 batteries and all-solid-state batteries to boost the energy density, going beyond the Li-ion battery technology.

Biography

Dr. Xiangwen Gao received his Ph.D. degree in Materials Science from the University of Oxford in 2018, after which he worked as a postdoc researcher in Prof. John B. Goodenough’s (2019 Noble Prize laureate in Chemistry) lab at the University of Texas at Austin. Xiangwen currently works as a senior postdoc research fellow with Prof. Peter G. Bruce FRS at the University of Oxford and the Faraday Institute. His research focuses on advanced energy storage and conversion systems, including aprotic Li-O2 batteries, multivalent-ion batteries, Li/Na-ion batteries, Li metal batteries. His recent research interest falls in implementing lithium metal as the anode to increase the energy density. Xiangwen serves as an early career research editorial board member in Materials Today Energy, SusMat. Xiangwen is the author and co-author of 29 peer-reviewed papers, including 10 papers as first-author and 6 papers as the corresponding author in leading journals including Nature Energy (1), Nature Materials (2), Joule (4), Angewandte Chemie (1) with over 2,000 citations and an h-index of 17.
