Prospects of Using Lignin Derivatives as Organic Electrode Materials for Lithium Batteries

摘要

In this paper, the influence of the lignin extraction method (Klason lignin and alkaline lignin) from natural raw materials (husks of rice, buckwheat, sunflower and rice straw) on its electrochemical behavior has been studied. The chemical composition and physical features were characterized by EDX, XRD, IR, and ~(13)C NMR methods. Electrochemical behavior of the lignins was investigated by galvanostatic discharge vs. Li~+/Li. The most promising method of delignification from the point of view of practical application as lithium cell electrode was discussed. The results demonstrate the potential of lignin based battery to be used as a cathode material for a low-rate power sources.
