Solid-state double layer capacitors and protonic cell fabricated with dextran from leuconostoc mesenteroides based green polymer electrolyte

Glycerolized dextran-ammonium nitrate (NH4NO3) biopolymer electrolytes are prepared by solution cast technique. The addition of 20 wt% glycerol has increased the conductivity value from (3.00 ± 1.60) × 10−5 S cm−1 to (1.15 ± 0.08) × 10−3 S cm−1. The study of ionic conductivities at high temperature...
