Templated mesoporous carbons for supercapacitor application
Mesoporous carbons prepared by an inverse replica technique have been used as electrodes for electrochemical capacitors. Such well sized carbons were prepared from mesostructured SBA-16 silica materials that served as templates whereas polyfurfuryl alcohol was the carbon precursor. Two highly mesoporous carbons characterized by 3 and 8 nm average pore diameter were tested in various electrolyti...
متن کاملNanoporous carbons through direct carbonization of a zeolitic imidazolate framework for supercapacitor electrodes.
Nanoporous carbons with high surface area are achieved through direct carbonization of a commercially available zeolitic imidazolate framework (ZIF-8) without any additional carbon sources. The resultant nanoporous carbons exhibit high electrochemical capacitances in an acidic aqueous electrolyte.
متن کاملMetal–organic framework (MOF) as a template for syntheses of nanoporous carbons as electrode materials for supercapacitor
Five nanoporous carbons (NPCs) were prepared by polymerizing and then carbonizing carbon precursor of furfuryl alcohol accommodated in a porous metal–organic framework (MOF-5, [Zn4O(bdc)3], bdc = 1,4-benzenedicarboxylate) template. The Brunauer–Emmett– Teller (BET) surface areas for five NPC samples obtained by carbonizing at the temperatures from 530 to 1000 C fall into the range from 1140 to ...
متن کاملBoric acid-mediated B,N-codoped chitosan-derived porous carbons with a high surface area and greatly improved supercapacitor performance.
This work reports an efficient strategy to synthesize B,N-codoped porous carbons with a high specific surface area using chitosan as the carbon precursor with the help of boric acid, featuring a high specific capacitance, large operation voltage and excellent cycle stability for supercapacitors.
متن کاملThe Composite Supercapacitor
Inspired by the design of composite materials, a novel composite supercapacitor is proposed comprising an integrated cell with high powerand high energy-related electrode materials so that the composite electrochemical double layer capacitor (EDLC) is the equivalent circuit of a high power EDLC of power P1 and energy E1 and a high energy EDLC of power P2 and energy E2 connected in parallel. A m...
