摘要

Abstract

In this work

a sponge-like polysulfonamide (PSA)/SiO

composite membrane is unprecedentedly prepared by the phase inversion method

and successfully demonstrated as a novel separator of lithium-ion batteries (LIBs). Compared to the commercial polypropylene (PP) separator

the sponge-like PSA/SiO

composite possesses better physical and electrochemical properties

such as higher porosity

ionic conductivity

thermal stability and flame retarding ability. The LiCoO

/Li half-cells using the sponge-like composite separator demonstrate superior rate capability and cyclability over those using the commercial PP separator. Moreover

the sponge-like composite separator can ensure the normal operation of LiCoO

/Li half-cell at an extremely high temperature of 90℃

while the commercial PP separator cannot. All these encouraging results suggest that this phase inversion based sponge-like PSA/SiO

composite separator is really a promising separator for high performance LIBs.
