The formation of nanocomposites carbon nanotubes/porous silicon for supercapacitor electrodes

Abstract

This work is devoted to the study of new functional nanocomposite materials for supercapacitor electrodes based on layers of porous silicon (PS), carbon nanotubes (CNTs) and tin oxide with a high specific surface area, uniform distribution of components, and stability during cycling. Methods for producing consolidated layers of carbon nanotubes on a developed surface of porous silicon have been developed and optimized. Nanocomposites have been created by uniformly applying a metal oxide component to the layers of carbon nanotubes/porous silicon (CNT/PS). Structural and electrochemical characteristics of electrodes based on CNT/PS and SnOx/CNT/PS have been studied.
