摘要: Abstract 1-Allyl-3-methylimidazolium chloride, [Amim] Cl was used to improve the stability and disrupt crystallinity of matrix formed between cellulose acetate (CA) lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) by solution casting technique. The sample composition CA:LiTFSI:[Amim] (14 wt.%:6 wt.%:80 wt.%) exhibits highest ionic conductivity has greater ability retain minimum reduction value 1.75 × 10−3 S cm−1 even after 30 days storage at room temperature. Increase in doping induces structural disorderliness which is revealed XRD analysis. This due complexation added constituents evident from variation FTIR spectra. relaxation time Li+ ions reduced increase amorphous region as observed shift loss tangent peaks higher frequencies thus enhancing conductivity.
