(EP114272-A)      . Rechargeable electrochemical storage cell    having an anode    and a cathode    which are each made from a synthetic polymer    and are surrounded by a liquid electrolyte , the polymers being electrochemically reversibly doped with ionic doping substances, characterised in that both the anode    and the cathode    are made of a type of synthetic polymer    which has triarylmethane units as the basic structural element.    (6pp)    (US4532195-A)      Rechargeable electrochemical storage cell has an anode and cathode both provided with a core of graphite felt satd. with a soln. of polymer which has triaromatic units as basic modules and is nonconjugated along a main chain.    The    surrounding electrolyte comprises lithium iodide dissolved in THF or sodium iodide dissolved in diglyme.    The anode polymer has OH gps. and is doped with alkali(ne earth) metal.    Monoisocyanate is added to convert the OH gps. to urethane gps.    The cathode polymer is doped with chalcogen.    ADVANTAGE -   The cell has high operating reliability and long life.    (5pp)    (EP114272-B)      . Rechargeable electrochemical storage cell having an anode and a cathode which are each made from a synthetic polymer and are surrounded by a liquid electrolyte , the polymers being electrochemically reversibly doped with ionic doping substances, characterised in that both the anode and the cathode are made of a type of synthetic polymer which has triarylmethane units as the basic structural element.    (DE3248076-C)      A rechargeable electrochemical storage battery contains an anode and a cathode made from a polymer based on triarylmethane units. The anode is doped with an alkali and/or alkaline earth metal and the cathode with I, Br and/or elements of gp. 6, esp. Se and S. The liq. electrolyte is a satd. soln. of LiI in tetrahydrofuran or a satd. soln. of NaI in 'diglymes'. The OH in the anode forming polymer are pref. converted to urethane gps. by addn. of monoisocyanate.    USE/ADVANTAGE -   As high energy, high capacity battery; the battery is very reliable and has a long operational life.    (5pp)
