Abstract: Nitrogenized electronic conductive polymers, their preparation processes, electrochromic display cell and electrochemical generators using these polymers.The polymers according to the invention in reduced form are in accordance with formula [NH--CH.dbd.CH.sub.n --].sub.x, in a first oxidized form with formula [N--CH--CH.sub.n N--CH.dbd.CH.sub.n ].sub.y n and in a second oxidized form with formula [N--CH.dbd.CH.sub.n --].sub.x X.sup.-, in which n is an integer between 1 and 20, x an integer between 10 and 1,000,000, y an integer between 5 and 500,000 and X.sup.- an anion and in which all or part of the hydrogens carried by the acetylene carbons can optionally be substituted by electron donor or acceptor groups or reactive groups.These polymers can be used as positive electrode material in an electrochemical generator filled with an electrolyte and having two current collectors, a negative electrode material being constituted by lithium or a lithium-aluminum alloy.

Abstract: Electrochemical generator comprising an anode compartment and a cathode compartment, separated by a semipermeable diaphragm and each containing an active electrode material and an electrolyte, the active electrode material of at least one of the compartments being constituted by an electronically conductive organic polymer, wherein in one of these compartments in which the active electrode material is an organic polymer, the electrolyte of said compartment comprises an electroactive compound, which is soluble in the electrolyte and has a redox potential which is close to that of the organic polymer with which it is in contact.
