Investigation of poly(methyl-methacrylate)-poly(acrylonitrile) blended polymer electrolytes with alumina filler for lithium-ion energy storage device

Three types of polymer electrolyte systems are fabricated based on PMMA, PAN and PAN/PMMA host polymer through the solution cast method. A consistent amount of lithium trifluoromethanesulfonate (LiCF3SO3), ethylene carbonate (EC) and aluminium oxide (Al2O3) are added to the host polymer. The mixture...
