摘要:

超交联聚合物具有稳定的化学性质、较高的比表面积和孔隙率,使其在诸多领域均展现出广阔的应用前景。 本文采用外交联剂“编织”法制备超交联聚萘基聚合物(MON),以其为前驱体,采用化学活化法制备超交联聚萘基微孔炭(MONC-800-1、MONC-800-2和MONC-800-3)。 结果表明,MONC-800-2的比表面积达2002.90 m2/g,微孔率为90.10%。 在1.0 A/g电流密度下,MONC-800-2的比电容为254.0 F/g。 组装成对称型超级电容器,比电容为43.0 F/g,功率密度为500 W/kg时,能量密度为5.97 Wh/kg。 循环5000次依然具有94.55%的电容保持率和99.91%的库伦效率。 该研究为超交联聚合物衍生炭材料应用于超级电容器储能提供参考。

Abstract:

With superior chemical stability, high specific surface area and porosity, the hypercrosslinked polymers are of great interests in the field of energy conversion and storage. Here, a hypercrosslinked poly(naphthalene-based) polymer (MON) was synthesized using an external cross-linking agent via a novel “knitting” method. Following this, MON-derived microporous carbon (MONC-800-2) was prepared via chemical activation for advanced supercapacitors. The MONC-800-2 features a high specific surface area of 2002.90 m2/g and microporosity of 90.10%. The MONC-800-2 shows a superior specific capacity of 254.0 F/g at current density of 1.0 A/g. Consequently, the assembled symmetrical supercapacitor with MONC-800-2 displays a high specific capacity of 43.0 F/g, superior cycling stability (with a capacity retention rate of 94.55% at 2.0 A/g over 5000 cycles), high Coulomb efficiency of 99.91%, and good energy density of 5.97 Wh/kg at a power density of 500 W/kg. This work offers valuable insights into the application of hypercrosslinked polymers-derived carbon materials in supercapacitors.
