A secondary battery is described comprising an anode means, a cathode means, and an electrolyte at least one of the electrode means including as an electrode active material a conjugated polymer which is characterized as having conjugated unsaturation along a main backbone chain thereof. The polymer is either oxidized or reduced to an electrically conducting state wherein it is doped with at least one ionic dopant species. The electrolyte comprises the ionic dopant species or a compound ionizable to form the ionic dopant species; and electrolyte is non-aqueous and inert with respect to the electrodes; wherein the conjugated polymer is doped with an anionic dopant species to a p-type electrically conducting state; wherein the anionic dopant species is selected from the group consisting of halide ions, ClO/sub 4/-, PF/sub 6/-, AsF/sub 6/-, AsF/sub 4/-, SO/sub 3/CF/sub 3/-, and BF/sub 4/-.
