•Bound water proportion increase with increase in the degree of carboxylation (DC).•Activation energy decrease with increase in the DC.•CCS6 with highest DC remains 57.2% of specific capacitance at -7 °C. Chitosan (CS) is the most abundant cationic biopolymer on earth. However, the ionic conductivit...
