摘要	NaA-type zeolite/poly(vinylidene fluoride-co-hexafluoro-propylene) (PVDF-HFP)-coated PET nonwoven composite separator is demonstrated for application in lithium-ion batteries. The morphology, thermal stability and electrochemical performance of the composite separator were investigated. Results indicate NaA zeolite with stable physico-chemical properties and unique microstructure enables not only significantly enhanced thermal resistance, but also excellent wettability, for example the dimensional shrinkage of this separator was lower than 2% at 170 degrees C for 1 h and the ionic conductivity was up to 2.1 x 10(-3) S cm(-1) at 25 degrees C. The cell assembled with the present separator displayed superior cycling performance and higher discharge C-rate capacity than that assembled with commercial PP separator. NaA zeolite is preferable for high performance separator in lithium-ion battery. (C) 2015 Elsevier B.V. All rights reserved.
