Secondary battery

Abstract

PURPOSE:To make the environment for manufacting an electrode to be easily controlled for good preseration without allowing any rapid rise of charging voltage together with improvement in both charge-discharge efficiency and a cycle lifetime, by using, as an electrode material, organic conductive body obtained by reacting predetermined nitrogen oxide on predetermined heterocyclic compound. CONSTITUTION:An organic semiconductor obtained by reacting the nitrogen oxide shown by Eq. (1) on the condensed heterocyclic compound shown by Eq. (2) or (3) is employed as at least one of positive and negative electrodes. In the equations, X and m indicate an inorganic group including halogen and integer 1 or 2 respectively, R<1> and R<2> represent hydrogen atom, alkyl group, nitro group, etc., Y indicates >N-R<3>, >0, >S, and >Se, and R<3> represents hydrogen atom, alkyl group, and aryl group. It is preferable that the reaction of the nitrogen oxide shown by Eq. (1) on the condensed heterocyclic compound shown by Eq. (2) or (3) is generated with the presence of a solvent in which at least one of the compounds is resolved, in liquid phase.
