Abstract
A high surface area electrode formed from filler particles having a high surface to volume ratio in a binder able to support the conduction of ions. The binder may be a hydrophilic polymer and hydrogel able to swell to incorporate a solvent and its dissolved ionic material while retaining its mechanical strength. The swelling may be regulated by control of the degree of cross-linking of the binder material.
