1. A method for storing energy, comprising:
at least one of flowing an electrical current through a gel electrolyte layer of a capacitor, and developing a charge separation across the gel electrolyte layer of the capacitor,
wherein the capacitor comprises:
a first electrically conducting layer;
an electrolyte layer comprising:
poly(vinylphosphonic acid);
a polymer mesh or aluminum mesh reinforcement, and
a molybdate redox mediator in an amount in a range of from 1.0 to 20.0 wt. % of a total electrolyte weight,
wherein the electrolyte is in gel form; and
a second electrically conducting layer,
wherein the electrolyte layer is sandwiched between the electrically conducting layers.
