<p>A reversible electrochemical cell uses as electrode-active material a polymer of formula: <CHEM> (R<1> and R<2> hydrogen, alkyl or alkoxy, m is 2 or more). The polymer is obtained by first forming a polymeric sulphonium salt of the general formula: <CHEM> (R<1> and R<2> as defined, R<3> and R<4> C1-20 hydrocarbon, X a counter ion, and n >/= m >/= 2) and subjecting the polymeric sulphonium salt to decomposition treatment in an inert atmosphere.</p> |
