Composite separator based on PI film for advanced lithium metal batteries
文献摘要：
Lithium(Li)metal batteries have received extensive research focusing on the dendrite growth issue on account of the high chemical activity of Li anode.While,thermal safety,as one of the important security concerns facing the further application,gets little attention.Here,the high-performance polyimide film is successfully developed to enhance the safety margin based on the excellent mechanical strength and heat resistance corresponding to the traditional separator.And,the polyimide film with the MoS2 coating made by spraying method as the composite separator can not only improve the wettability to the elec-trolyte,but also in-situ form an artificial layer with the low nucleation barrier for the Li ions.When used in both the coin cell and the pouch cell,all achieve the outstanding cycling stability and the coulombic efficiency.Specially,the in-situ Li ions nucleation behaviors are investigated by optical microscopy in the capillary cell.The electric field intensity at the Li anode surface is also simulated by COMSOL Multiphysics to further elucidate the effect of the coating.
