超交联聚萘基微孔炭的制备及其电化学性能
Preparation of Hypercrosslinked Poly(Naphthalene-based) Microporous Carbon and Its Electrochemical Properties
摘要
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.关键词
