Abstract: The present invention relates to a method for using a battery which has an electrode that functions according to a mechanism of complexation of anions and within which the electrode active material is a polyviologen, characterized in that said polyviologen is a material that is insoluble in the electrolyte of said battery and in that the electrochemical conditions for use of said battery are adjusted so that its charge/discharge cycling process is established on the basis of the 1-electron redox reaction between the 1-electron oxidized form of the viologen units of said polyviologen, termed cation radical, and their totally reduced form, termed neutral form of the polyviologen.
