New composite material formulations based on graphene are to be investigated; such as electrodes of high energy density. Electrolytic Double layer Capacitors (EDLCs) are commercially known as supercapacitors. Supercapacitor is finding its place across many industry verticals; such as consumer electronics, transportation and industrial segments, due to its advanced features, like high power pulse, extended life and steadily lower cost for consumers. Nevertheless, practical capacitive behavior of pure graphene is lower than the anticipated value; mainly due to the serious agglomeration during both the preparation and application processes. Therefore, boosting the overall electrochemical performance of graphene-based materials still remains a great challenge. The main objectives of the project are the development of novel electrodes based on graphene-based composites in different structures; like one-dimensional (1D) fibers, two-dimensional (2D) thin films and three-dimensional (3D) foams with good performance characteristics and clear reproducibility and the establishment of a scalable electrode production process where all the parameters are optimized and clearly defined in order to achieve constant quality and performance of the produced material towards subsequent successful commercialization steps.
