The polymerelectrolyte membrane prepared by blending the cellulose acetate,poly(ethylene oxide), and lithium chlorate could be potentially used asa polymer electrolyte for lithium ion battery application.

Benzyl acetate is found in alcoholic beverages

Cellulose acetate is used as an additive to increase ionicconductivity and mechanical property of polymer electrolyte membranes.

Never-dried and once-dried hardwood celluloses were oxidized by a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated system, and highly crystalline and individualized cellulose nanofibers, dispersed in water, were prepared by mechanical treatment of the oxidized cellulose/water slurries. When carboxylate contents formed from the primary hydroxyl groups of the celluloses reached approximately 1.5 mmol/g, the oxidized cellulose/water slurries were mostly converted to transparent and highly viscous dispersions by mechanical treatment. Transmission electron microscopic observation showed that the dispersions consisted of individualized cellulose nanofibers 3−4 nm in width and a few microns in length. No intrinsic differences between never-dried and once-dried celluloses were found for preparing the dispersion, as long as carboxylate contents in the TEMPO-oxidized celluloses reached approximately 1.5 mmol/g. Changes in viscosity of the dispersions during the mechanical treatment corresponded with those in the dispersed states of the cellulose nanofibers in water.

The increase the percentage of cellulose acetate in membranes do notdirectly effect on the ionic conductivity, and the highest ionicconductivity of membranes about 5,7 × 10-4 S/cm wasobserved in SA/PEO/LiClO4 membrane with cellulose ratio of10-25% (w/w).
