摘要
Abstract
EVOH-SO3 Li/PET Li-ion battery composite membranes were prepared by means of alternated electrostatic spinning,then the morphology of the membranes was observed by scanning electron microscope,and the electrochemical properties of the membranes were tested by using an electrochemistry work station.The results show that the average diameter of EVOH-SO3Li/PET fibre is 387nm,both two kinds of fibres exhibit uniform net-like structure.Compared with pure EVOHSO3Li fibre,adhesion phenomenon of modified EVOH-SO3 Li/PET fibre is not obvious anymore,and the surface of EVOH-SO3Li/PET fibre becomes more smooth with enlarged pores between adjacent fibres;the electrochemical window of EVOH-SO3Li/PET separator is 5.3V,bulk resistance of EVOH-SO3Li/PET is decreased to 212.31Ω,and the ion conductivity of EVOH-SO3Li/PET separator is 2.347 × 10-3 S/cm,the properties of EVOH-SO3Li/PET membranes are improved compared with EVOH-SO3Li.关键词
