英文摘要	In order to overcome severe capacity fading of Ni-rich layered oxides Li[N1-x-yCoxMny]O-2 cathode of lithium-ion battery at elevated voltage, a composite membrane consisting of poly(ethylene terephthalate) (PET) nonwoven fabric incorporated with poly(ethyl alpha-cyanoacrylate) was investigated as polymer matrix of gel polymer electrolyte (GPE). The ionic conductivity of the GPE based on this composite membrane saturated with a liquid electrolyte (LE) of 1 M LiPF6 in carbonate solvents is 2.54 mS cm(-1) at room temperature, and the stable electrochemical voltage window can be up to 4.7 V. Its electrochemical performance is evaluated by using full cell with Li[Ni0.5Co0.2Mn0.3]O-2 as cathode and graphite as anode. These results demonstrate that the as-prepared GPE remarkably improves the cyclability at the high cut-off voltage compared to the commercial liquid electrolyte. (C) 2015 Elsevier B.V.
