Abstract
Silicon carbide materials have attracted much attention in supercapacitor as electrode materials. Solution blowing process is a novel method to fabricate nanofibers with high productivity. In this study, silicon carbide nanofiber membranes (SiC-NFMs) with porous architecture were prepared via solution blowing process and subsequent calcination, which exhibiting good electrochemical performance as electrode materials for supercapacitors. As a simple and efficient nanofiber fabricating method, solution blowing was introduced here to produce as-spun precursor nanofiber membranes which would be pyrolysed to Silicon carbide products. The porous architecture of SiC-NFMs, which was composed of mesopores in each single nanofiber and macropores between nanofibers, led to the excellent electrochemical performance. The results showed that these membranes were of high specific capacitance (∼189Fg−1) and outstanding cycling stability (91.7% retention after 3000 cycles). This solution blowing method would find application to produce SiC-NFMs which can be used as electrode materials for supercapacitors with good performance.
