title: Dimensional stability and electrochemical behaviour of ZrO2incorporated electrospun PVdF-HFP based nanocomposite polymer membrane electrolyte for Li-ion capacitors.
abstract: Different weight percentages of ZrO2(0, 3, 5, 7 and 10 wt%) incorporated electrospun PVDF-HFP nanocomposite polymer membranes (esCPMs) were prepared by electrospinning technique. They were activated by soaking in 1 M LiPF6containing 1:1 volume ratio of EC : DMC (ethylene carbonate:dimethyl carbonate) to get electrospun nanocomposite polymer membrane electrolytes (esCPMEs). The influence of ZrO2on the physical, mechanical and electrochemical properties of esCPM was studied in detail. Finally, coin type Li-ion capacitor cell was assembled using LiCo0.2Mn1.8O4as the cathode, Activated carbon as the anode and the esCPME containing 7 wt% of ZrO2as the separator, which delivered a discharge capacitance of 182.5 Fg-1at the current density of 1Ag-1and retained 92% of its initial discharge capacitance even after 2,000 cycles. It revealed that the electrospun PVdF-HFP/ZrO2based nanocomposite membrane electrolyte could be used as a good candidate for high performance Li-ion capacitors.
