Cellulose and lignin are two of the key-biopolymer components from the forest. Combining derivatives of those with additional redox systems and conductors, large-scale batteries and supercapacitors have been realized. Cellulose provides desired structure, at the nano-, meso- and macro-dimensions, and ligninsulphonate provide oxidation reaction. Adding reduction reaction, delivered from bio-pigments, with electronic conductors and electrolytes, an all-organic battery and supercapacitor technology has been developed. Large-volume manufacturing processing is currently being developed to realize a large-scale electrical energy storage technology for the grid, to achieve peak shaving and to balance supply and demand of electricity in our society. The production protocol includes classical paper-making, lamination and printing technologies.
