The main topic of the research group is focusing on electrochemical energy conversion and storage system, especially on the new electrode materials, interfacial properties and in-situ techniques. Li-ion and Na-ion batteries has attracted wide interests in the last decades, but their applications have been impeded by the limited energy/power density of the batteries. In order to settle down these issues, different strategies should be designed and utilized in the researches. In our group, we have utilized three strategies to achieve our researc goals:

      1）To search for high specific-energy type anode materials, including, Si, SiOx, P, Ge, and Sn with multiple-charge

alloy and high-electron transfer process for next-generation batteries;

      2）To improve the electrochemical performance of the electrodes by regulating the interfacial properties with new interface construction; 

      3）To understand electrode process and physical and electrochimcal nature by using different in-situ/ex-situ  techniques.
