Human activity generates an environmental impact increasingly important including in the field of transport and portable electronics. It is therefore essential to develop of new technologies capable of producing and storing elec. energy. In this context, org. material based battery can constitute an interesting alternative compared to inorg. ones. Less costly and toxic and allowing to involve other alkali cation (rather than Li+), since few years such materials are evoked in literature. However, their performance yet do not compete with that of involving inorg. cathodic material (i.e. Lithium iron phosphate). In this context, multi electron process can be the way to reach high performance org. compds. This can be done using phenothiazine which, through an adapted chem. modification, can undergo a two electron oxidn. in the potential window stability of classical electrolyte. This work is dedicated to the impact of N-methyl-phenothiazine chem. modification on its electrochem. behavior. The stability of oxidized forms of modified phenothiazine is investigated helping to select the best monomer to be involved as cathodic polymer material in battery. [on SciFinder(R)]
