摘要:
摘 要:为研究一种新型的锂离子电池隔膜材料, 以聚乙烯 -乙烯醇共聚物( EVOH) 和1, 3 -
丙烷磺酸内酯为原料, 叔丁醇锂为催化剂, 通过化学修饰得到 EVOH - SO3 Li 聚合物电解质, 经高压
静电纺丝制备成无纺布薄膜. 采用红外光谱( FTIR) 对合成电解质的化学结构进行表征, 并运用扫
描电镜观察分析了薄膜的微观形貌. 结果表明: 成功接枝磺酸根, EVOH - SO3 Li 聚合物被合成出;
纤维直径分布在150 ~ 220 nm 之间, 纤维孔径可达到电池隔膜的要求.
Abstract:
Abstract: 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 ionic
polyme, and the SEM is utilized to characterize the features microcosmic of the non- woven. Results show that graft
polymer 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.
