Abstract

Different parts of the hemp plant (Cannabis sativa) has different applications namely the seeds and flowers are used in preparing healthy foods, organic body care, and other nutraceuticals, the fibers and stalks are used in clothing, construction materials, paper, biofuel, plastic composites, and more. Similarly, in this research work, we have used hemp bast (HB) for application in energy storage devices like lithium and sodium ion batteries (LIBs and SIBs). From the HB we derived partially graphitized carbonaceous material (HBC) using simple pyrolysis process followed by washing with nitric acid. The chemical and physical properties of HBC are analysed using XRD, Raman spectroscopy, XPS, FE-SEM, and BET. The electrochemical properties of HBC are analysed using it as an anode in LIBs and SIBs. The anode electrode fabricated using HBC is found to have good cycling performance, capacity, and rate capability in both the LIBs and SIBs.
