Biodegradable polymer electrolytes materials consisting salt dissolved in high molecular weight chitosan acetate was studied. Mobility and number density of mobile ions of chitosan acetate doped with NH4CF3SO-, and chitosan acetate-NH4Cr,S03-DMC system has been calculated using the Rice and Roth model. The conductivity improved by as much as two orders of magnitude with added salt concentration but the correlation was not apparent. The addition of plasticizer further improved the conductivity. The polymer electrolytes developed were then used in batteries and fuel cells and their performance were evaluated.
