A multi-layer electrode structure is provided comprised of a plurality of electrode
layers composed of a binder and an electrode material and coated on a current-collecting
member, each of the electrode layers including a macromolecular substance wherein
a first electrode layer in contact with the current-collecting member and the second
electrode layer in contact with the first electrode layer are formed of different
constituents or have different proportions of the same constituent. A method of
forming the multi-layer electrode structures as well as a battery and double-layer
capacitor formed from the multi-layer electrode structures are also disclosed.
