Preparation of Polypyrrole/Anthraquinone-2-sulfonate Nanocomposite and Application in Li-Ion Battery

Year: 2014

Type: article

Abstract: 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.Keywords polypyrrole; anthraquinone-2-sulfonate; Li-ion battery; cathode material 目前, 锂离子二次电池由于其高能量和功率密度得到广泛应用, 特别是在便携式电子设备领域.另外, 相比其它类型的二次电池, 锂离子电池兼顾了电动汽车所需的比能量、比功率、安全和寿命等特性以及相对低的成本, 在新储能发电体系发展成熟以前, 锂离子电池是发展电动汽车最好的选择.现阶段锂离子电池正极材料一般采用钴酸锂、三元材料、锰酸锂和磷酸铁锂等 [1～4] .大规模的生产和应用过渡金属基正极材料(如 Mn, Fe, Co, Ni)会引发资源和环境问题, 其开采和制备都需要消耗大量能量, 因此, 需要开发比容量更高、在自然界中储量更为丰富的绿色能源材料.
