Abstract
Abstract An electrochemical cell or battery contains two or more electrodes, the active material of one or more of the electrodes consisting of an electrically conductive, electrochemically oxidizable and/or reducible polymer. The electrolyte consists of one or more ionic or ionizable compounds, as conductive salts, dissolved or suspended in an organic electrolyte solvent, the electrolyte containing one or more organic complex ligands possessing ethylene glycol ether units.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
100 words
An electrochemical cell or battery containing two or more electrodes and an electrolyte consisting of a solution or suspension of an ionic or ionizable compound, as a conductive salt, in an organic electrolyte solvent which is inert to the electrodes, one or more of the electrodes containing, as active electrode material, an electrochemically oxidizable and/or reducible polymer which, in the oxidized and/or reduced state, has an electrical conductivity greater than 10 -2 Ω -1 cm -1 , wherein the electrolyte contains an organic complex ligand possessing units of the formula (--X--CH.sub.2 --CH.sub.2 --) where X is O, S or NH.
Claim 2
Dependent Claim
100 words
An electrochemical cell or battery containing two or more electrodes and an electrolyte consisting of a solution or suspension of an ionic or ionizable compound, as a conductive salt, in an organic electrolyte solvent which is inert to the electrodes, one or more of the electrodes containing, as active electrode material, an electrochemically oxidizable and/or reducible polymer which, in the oxidized and/or reduced state, has an electrical conductivity greater than 10 -2 Ω -1 cm -1 , wherein the electrolyte contains an organic complex ligand possessing units of the formula (--X--CH.sub.2 --CH.sub.2 --) where X is O, S or NH.
