An electrochemical generator includes a first electrode covered by a passivation layer having a compound formed by repetition of a pattern of the following formula (7): in which: n is an integer comprised between 1 and 10, preferably between 1 and 4; Rand Rare identical or different and chosen independently from the group formed by &#x2014;CH&#x2014;, a cyclic or acyclic, linear or branched alkyl chain; Ris chosen from the group formed by &#x2014;CH, a cyclic or acyclic, linear or branched alkyl chain, and a group of the following formula (8): in which: N is a mono or polycyclic, aromatic hydrocarbonated group chosen from the group formed by phenyl, aryl groups, condensed polyaromatic groups, which may be substituted;

Electrochemical generator and method of producing such a generator

The invention relates to a diazonium aryl salt devoid of hydroxyl functions of the following general formula (1):XN&#x2261;N-A-R&#x2014;(OR)&#x2014;O&#x2014;R-A'-N&#x2261;NX&#x2003;&#x2003;(1)in which: n is in a range of from 1 to 10, preferably from 1 to 4, Xrepresents a counter-ion of the diazonium cation selected from the group consisting of halogenides, BF&#x2014;, NO&#x2014;, HSO&#x2014;, PF&#x2014;, CHCOO&#x2014;, N(SOCF)&#x2014;, CFSO&#x2014;, CHSO&#x2014;, CFCOO&#x2014;, (CHO)(H)PO&#x2014;, and N(CN)&#x2014;;R, Rand Rare identical or different and are independently selected from the group consisting of &#x2014;CH&#x2014;, a cyclic alkyl group, an acyclic alkyl group, a linear alkyl group, and a branched alkyl group; andA and A&#x2032; are identical or different and independently represent a mono or polycyclic, aromatic hydrocarbonated group chosen from the group formed by phenyl, aryl groups, condensed polyaromatic groups, which may be substituted.
