The present invention concerns the use, as an active electrode material, of compounds comprising at least one entity of formula (I): in which the phenyl group is substituted with one to four identical or different substituent(s) R, chosen from a hydrogen atom, a halogen atom chosen from fluorine, chlorine, bromine or iodine, a —C(═S)—S—C+ group, an —O—C+ group, an —S—C+ group, C+ being an alkali cation chosen from Li+, Na+ and K+, a (C1-C 12) alkyl radical, a (C2-C12) alkenyl radical, a (C6-C14) aryl or heteroaryl radical; or two vicinal substituents R that can, if appropriate, be linked to each other to together form a 3- to 7-membered ring optionally including another heteroatom chosen from N, O or S; in the base or salt form; and the tautomeric forms of same. It also concerns an electrode material, an electrode and a lithium, sodium or potassium secondary battery, obtained from these compounds.
