Anthraquinone-2-sulfonate (AQS) was prepared from phthalic anhydride by modified phthalic anhydride method and sulphonation method. Anthraquinone was synthesized by oxidation of sulfuric acid and phthalic anhydride. Then sulfonic acid group was introduced to the anthraquinone with fuming sulfuric acid to form AQS. And then polypyrrole (PPy)/AQS composite was synthesized by electrochemical in-situ polymerization reaction on current collector from the aqueous solution containing pyrrole and AQS. The prepared PPy/AQS composite material exhibited good charge/discharge property and cycling stability in the conventional organic electrolyte as organic electrode in lithium ion batteries.
Key words: polypyrrole; anthraquinone-2-sulfonate; Li-ion battery; cathode material
