To obtain a kind of new material of lithium ion battery septum, with Lithium Tert- butoxide as the cat-alyst,a polymer electolyte of poly ( ethylene- co- vinyl alcohol) end- capped with lithium sulfonate ( EVOH- SO3 Li)is synthesized from poly( ethylene- co- vinyl alcohol) ( EVOH) and 1, 3- propane sultone, the EVOH- SO3 Li non- wov-en membrane is prepared by electrospinning technique. FT- IR was used to characterize the structure of ionicpolyme, and the SEM is utilized to characterize the features microcosmic of the non- woven. Results show that graftpolymer of EVOH- SO3 Li is synthesized successfully. The fiber diameter between 150 nm - 210 nm, microporous di-ameter reached the requirements lithium ion battery septum.
