          讲座内容:

          Considerable effort has been dedicated to improving current rechargeable lithium-ion batteries and to developing new materials, owing to the ever-increasing demand for high-performing, safe and economical energy storages for various applications. An exciting research direction is on solid Li-ion electrolyte, which has large electrochemical stability window and improved safety in comparison to conventional liquid electrolyte with leakage, flammability and poor chemical stability issues. In addition, solid electrolyte can offer one of the most promising approaches to suppress Li metal dendrite to enable the “holy grail” high-energy lithium metal batteries. However, realization of such a composite solid electrolyte with ionic conductivity comparable to a liquid electrolyte remains a significant challenge. In this talk, I will introduce a composite polymer electrolyte with inorganic Li+-conductive nanowires, which shows three orders of magnitude enhancement in ionic conductivity. More results reveal that aligned nanowires could further increase conductivity due to a continuous fast ion-conducting pathway on the nanowire without crossing junctions. In addition, the approaches by using interface layer to prevent Li dendrite will be also indicated in this talk.
