چکیده انگلیسی
A gel polymer electrolyte based on polyacrylonitrile (PAN)/poly(vinyl alcohol) (PVA) blending membrane have been fabricated through non-solvent induced phase separation (NIPS) method followed by activation in liquid electrolyte of 1.0â¯M LiPF6 in carbonate solvent. The blending compatibility of PVA/PAN is investigated through thermodynamics analyses and demonstrates the miscibility of PAN/PVA blending system. The blending membranes with weight ratio of PVA/PAN=â¯10:90 and 20:80 have great effect on morphology of both top and bottom surface. This characteristic exhibits the high electrolyte uptake (up to 585%), acceptable thermal stability, excellent ionic conductivity and electrochemical stability (up to 5.28â¯V). The application of PAN/PVA blending membrane has been demonstrated by a coin cell using Li metal as counter electrode at 1C, resulting in better long-term cycle stability in comparison to cells with Celgard2320 separator and the highest capacity retention of 96%.
