With the help of cross-scale theoretical simulation and calculation, atomic scale experimental control and in-situ linkage measurement and other cutting-edge interdisciplinary subjects, the study on high-performance lithium battery materials is currently the focus in energy storage research field. By studying the symmetry-breaking and recombination mechanism of crystal structural motifs at the interface, our group has explored the interfacial problems of lithium batteries from micro scale to atomic scale, providing valuable references for the research of next-generation lithium battery materials. In addition, our group has established in-situ interfacial collaborative research system at atomic scale, to carry out basic research on the reconstructive mechanism and law of interfacial electrochemical, and electrochemical kinetics of interfacial structure.
