RESEARCH INTEREST

Na-ion batteries are emerging as an alternative of Li-ion batteries due to the high abundance and low cost of Na. However, the larger ionic radius of Na-ion leads to a solid electrolyte interface (SEI) crack and further electrolyte decomposition during repeated expansion and contraction of the electrode. Constructing stable and efficient SEI is among the most effective strategies to inhibit the excessive decomposition of electrolyte and achieve superior cycling performance for batteries. The electrolyte additives are promising ways to overcome the above problem. In my research I will mainly focus on the development of electrolyte additives for Na-ion batteries, study the effects on the electrochemical performance of sulfides electrodes in Na cells.
