Abstract [en]

There is currently a strong need for the development of inexpensive, flexible, light-weight and environmentally friendly energy storage devices. This has led to the development of a range of new paper-based electrode materials, batteries and supercapacitors. In this presentation it will be shown that flexible nanocellulose and polypyrrole composites, manufactured by chemical polymerization of pyrrole on a nanocellulose substrate, can be used as electrodes in water-based charge storage devices [1-3]. The latter paper-based devices exhibit both high charge storage capacities and excellent power capabilities due to the combination of the large surface area (up to 250 m2/g) of the nanocellulose and the thin (i.e. 50 nm) layer of polypyrrole on the nanocellulose fibres. The composite synthesis method and the electrochemical properties of the composites will be discussed, as well as the possibilities of using polypyrrole coated nanocellulose fibres in the manufacturing of free-standing, high active mass paper electrodes [4-7]. With the latter approach, devices with unprecedented cell areal capacitances at high current densities during thousands of cycles in aqueous solutions can be readily realised. The present type of composites provides new exciting possibilities for the development of green and foldable devices for a range of novel applications, many of which are incompatible with conventional batteries and supercapacitors.
