Biomass derived carbon materials for electrochemical energy storage devices

Abstract

Abstract This paper presents water hyacinth and sensitive plant derived carbon as a biomass carbon with utility for electrochemical energy storage. The prepared samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Electrochemical properties of the carbon materials were investigated by using cyclic voltammetry and galvanostatic charge-discharge. The specific capacitance value of 38 and 16 F g-1 were observed for biomass carbon of water hyacinth and sensitive, respectively.
