Template‐Assisted Electrospinning of Bubbled Carbon Nanofibers as Binder‐Free Electrodes for High‐Performance Supercapacitors

Comparing the performance of recently reported electrospun carbon nanofiber (CNF)‐based supercapacitors, which use binders, we are reporting a binder‐free high‐performance supercapacitor based on porous bubbled surface carbon nanofibers (BCNFs). BCNFs have been synthesized by using a KIT‐6 silica template‐assisted electrospinning process, and they exhibit a high discharge specific capacitance of 287 F g−1 (79.7 mAh g−1). Brunauer−Emmett−Teller and FESEM analyses reveal that BCNFs have a large accessible surface area (593 m2 g−1) and well‐developed pore structures, leading to a high specific capacitance value. Furthermore, a BCNF supercapacitor exhibits good cyclic stability with improved capacity retention in aqueous electrolyte. The use of electrospinning and a hard template method for the synthesis avoids the use of aggressive materials and complicated activations, thereby making it an industry‐compatible process for large‐scale production. The present study, demonstrating the successful synthesis of BCNFs, is a major step ahead in the direction of developing new materials for binder‐free supercapacitors, which hold enormous potential for high‐performance energy storage devices.

Transferhydrierungsreaktionen, genauso wie Metathesereaktionen von Alkenen und Alkinen, sind von großer Bedeutung in der Synthesechemie. Ein gemeinsames Schlüsselmerkmal dieser Verfahren ist ihre Reversibilität, die davon herrührt, dass sowohl Startverbindungen als auch Produkte die gleiche Anzahl und Art von funktionellen Gruppen aufweisen und die Verfahren somit isofunktionell machen. Diese klassischen Reaktionen trugen in letzter Zeit dazu bei, neuartige Shuttle‐ und Metathesereaktionen zu entwickeln, die vielversprechend für die Synthesechemie sein könnten. Dieser Aufsatz beschreibt und ordnet aktuelle wie auch ältere Beispiele von Shuttle‐ und Metathesereaktionen (mit Ausnahme von Transferhydrierungen und Metathesereaktionen von Alkenen und Alkinen).

“…With the advent of the fi rst electrospinning apparatus in 1934, invented by Formhals, [ 1 ] electrospinning has become an important method used to obtain micro-and nano-fi bers. [2][3][4][5] Compared to the template method, [ 6 ] stretching method, [ 7 ] and self-assembly method, [ 8 ] it is much easier to use electrospinning to fabricate continuous fi bers, which have promising applications in the fi elds of tissue engineering, [9][10][11] fi ltration, [ 12,13 ] protective clothing, [ 14,15 ] lithium cells, [16][17][18][19] supercapacitors, [ 20,21 ] and oil adsorption. [ 22,23 ] It is generally known that the introduction of porous structure can signifi cantly extend the application of electrospinning.…”

Three different dopants are used to fabricate electrospun dopants/polystyrene (dopants/PS) composite fibers from PS solution and PS sol. The relative humidity and the influence of the dopants on the morphologies, diameter, porous structures, and dopant distribution of electrospun PS fibers are investigated. Compared to those obtained from PS solution, electrospun dopants/PS composite fibers from PS sol with hollow‐porous and multichannel hollow‐porous structures present significant advantages due to the multi‐stage degree of interfacial structure and diversity of the internal environment. In comparison to coaxial electrospun PS fibers, the electrospun dopants/PS composite fibers from PS sol obtained in one step have an improved yield and a simplified technological process simultaneously, leading to significant competitiveness in fields such as catalysis, fluidics gas storage, and sensing.
