研究方向:高能电池材料与电化学过程---材料、界面及原位表征技术

发展高性能的电化学能源体系需要在材料革新、界面调控及理解其电化学反应机理取得进展与突破。近年来全球锂离子电池的研发与生产倍受瞩目,然而其大规模应用仍然受制于其较低的能量密度、循环寿命及其安全性等。课题组的研究工作主要集中在高能化学电源方向,尤其关注锂离子电池及其它可充式离子嵌脱型电池的电极材料、界面调控及其原位表征技术的研究。我们目前的主要的基础研究课题包括:

1)发展高电压及多电子交换的正极材料;

2)发展功能电解液(含添加剂)调控电极的界面性能;

3)通过应用与发展原位表征技术(如高分辨的固体核磁谱技术\x-射线吸收谱技术)研究高能电极的电化学反应过程。


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 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 polyanion-type cathode materials with multiple-electron transfer process or high-voltage electrode materials;

2)To improve the electrochemical performance of the electrodes by regulating the interfacial properties with additives;

3)To understand electrode process by using different in-situ spectroscopic techniques.
