  • Process for the preparation of polyanilines, polyanilines obtained according to this process and their uses in the production of electrochemical generators
    Patent number: 4629540
    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.sub.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.
