Abstract
In this work, porous Cellulose/Poly (vinylidene fluoride hexafluoropropylene) membrane with the incorporation of different amount of titania nanoparticles is prepared by non solvent induced phase inversion (NIPS) method followed by hydrolysis with lithium hydroxide for deacetylation of cellulose acetate. The composite membranes provide interconnected porous structure with high porosity. Titania incorporation and surface modification of Poly (vinylidene fluoride hexafluoropropylene) in the membrane are investigated by Fourier-transform infrared absorbance and transmission tests. The results show that the modified membrane exhibits excellent thermal stability at 200 °C with just only 1% shrinkage and contains high ion conductivity (1.68 mS cm−1). Moreover for window 2.5–4.5V, the ceramic nanoparticles embedded membrane with optimal titania content enables the battery to deliver 97.34% capacity retention after running 100 cycles at 1C rate and to maintain the capacity up to 72% even for 500 cycles after continuing different cycling test with Lithium cobalt oxide/Lithium cell assembly.
