Abstract

Provided is an electrode that contributes to higher performance improvement of batteries and capacitors by selecting a dispersant not only for uniformalizing an electrode structure but also playing the performance improvement role for the batteries or capacitors. An electrode 1 includes an active material 2 and a conductive additive 3. The electrode 1 also includes a dispersant 5, and the dispersant 5 is adsorbed onto the surfaces of the conductive additive 3 and the active material 2. More preferably, the electrode 1 includes the dispersant 5 having at least one kind selected from a group consisting of molecular structures, atoms, and ions which acts as a charge transfer medium, and most preferably, the electrode 1 includes the dispersant 5 having the same charge as the charge transfer medium contained in the active material 2.
