以苯酐为起始原料,采用改进的苯酐法及磺化方法,首先通过硫酸氧化合成蒽醌,再通过发烟硫酸磺化在蒽醌的侧位上引入磺酸根,从而制备了含有电子转移活性的可溶于水的高纯度蒽醌-2-磺酸盐,然后通过电化学聚合反应在集流体上原位得到聚吡咯复合材料(PPy/AQS). 最后,将得到的PPy/AQS复合材料作为锂离子电池的有机电极材料,在常规的有机电解液中形成稳定的电池体系,具备储存和释放锂离子的能力,具有良好的充放电性能及循环稳定性.

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.
