<br/>One of the most debated topics in the energy world today is about the extent to which carbon-free renewable energy can be used in our day-to-day life. Since the two most popular sources of renewable energies; namely the solar and wind power are intermittent, they cannot match with the energy demand of human activity. Hence large-scale batteries are emerging as integral components of the energy solutions for the future to enable constant power delivery on the electrical grid. The current technologies for large scale electrical energy storage rely on raw materials that have limited abundance or expensive to manufacture. On this regard, we report the development of a safe and sustainable bio-based battery components using materials that are abundant and recyclable. Lignin being one of the most abundant biopolymers, qualifies to be one of the potential candidates, as it has quinone-aromatic chemical groups that can be employed to store and deliver electrical charges by reversible Faradaic reactions. But lignin is also an electrical insulating material. To enable those Faradaic reactions, we composite lignin with a conducting polymer and obtain a nanocomposite that is conducting electricity and thus provide electrons and ions to lignin. More specifically, we report the preparation and optimization of the composite electrode materials of lignosulfonate (LS) (lignin) and the conducting polymer (poly 3, 4-ethylenedioxythiophene; PEDOT) for energy storage application. Scaled-up synthesis route in aqueous media for low-cost environmentally friendly technology to make large volume batteries will be discussed. The results of the battery concept incorporating this  lignin/PEDOT based-positrode) and a bio-based negatrode; PACA (poly(1-amino-5-chloroanthraquinone)/PEDOT  in a water- based electrolyte along with cellulose based separator will be presented.<br/>
