In this article, a novel silicon-based electrode was designed with the facile solution methods. With the modification of highly conductive PEDOT:PSS layer on the SiNWs by the spin-coated method (SiNWs-PSS), three-dimensional (3D) porous network polyaniline nanofibers (PANI) film was uniformly electrodeposited on the silicon surface ([email protected]). The sheet resistances of the PEDOT:PSS layer with different surfactants as well as the deposition time of the PANI were investigated. After optimization, the fabricated [email protected] electrode displayed high capacitance about 301.71 mF cm-2 at the current density of 1mA cm-2, which enhanced ~29 fold comparing to 10.18 mF cm-2 of electrode without the PEDOT:PSS layer between the SiNWs and PANI ([email protected]), outperforming most values of the reported silicon-based electrodes. The electrode designed in this paper provides a new idea to fabricate high-performance of silicon-based micro-supercapacitors with the simple and low-temperature method.
