Outline
Due to the poor wettability and thermal stability of electrolyte, the application of traditional lithium ion battery separator in the field of high-performance and high safety battery is limited. The surface modification of the separator to realize its surface functionalization has become a feasible strategy to solve the inherent problems of lithium-ion battery separators. From perspective of surface physical modification and surface chemical modification, this paper elaborated respectively the features and cutting-edge dynamics of various surface modification methods, such as spray coating, dip coating, solution casting, electrospinning, chemical grafting, plasma, radiation grafting and UV grafting. The paper also indicated that developing multifunctional separators, intelligent response separators, and reducing modification costs would be the research directions for surface modification of lithium-ion battery separators in the future.
