The key to electrochemical energy storage systems such as Li/Na-ion batteries is materials. The traditional method for exploring new materials is trial-and-error, which often takes a dozen years during the research and development process from the materials discovery to application, being difficult to meet the requirement of the industry community to high-performance electrochemical energy storage materials. Therefore, in order to accelerate the research and development speed of new materials, it is urgently expected that we can understand the key scientific problems such as the synergistic regulation of electronic/ionic transport and interfacial stability from interdisciplinary perspective including physics, materials, chemistry and mathematics and organic fusion of theoretical, computational and experimental methods. In this talk, I will introduce the main progresses in this aspect by presenting our some researches, and look into the role of multiscale computation in designing the novel electrochemical energy storage materials.
