Claim 4:
5. A method of making a zinc-based battery, said method comprising:
activating two separate flexible current collectors;
coating a first activated current collector with a cathode ink layer;
soaking the chitosan-based polymer gel electrolyte film of claim 1 in a KOH solution for an interval of time to yield a swollen gel electrolyte;
dipping the swollen gel electrolyte in a chitosan-based polymer gel electrolyte solution to substantially coat all sides of the swollen gel electrolyte and positioning the dipped swollen gel electrolyte onto the cathode ink layer;
positioning a zinc layer onto the dipped swollen gel electrolyte layer; and
positioning a second activated current collector onto the zinc layer to yield the zinc-based battery.
