Abstract
Abstract Process for the preparation of polyanilines, polyanilines obtained according to this process and their uses in the production of electrochemical generators. This process consists of oxidizing a compound chosen from among aniline, para-aminodiphenylamine and their derivatives in a super acid in the liquid phase, having fluoride ions, e.g. in the eutectic NH 3 , HF, either chemically using an oxidizing agent, or electrochemically. The polyanilines obtained can be used as a positive electrode material (5) in an electrochemical generator having two current collectors (3) and (7) and a negative electrode material (9), e.g. constituted by lithium or a lithium-aluminum alloy.
