Energy storage application like batteries or supercapacitors call for new carbon electrode materials which can be designed with respect to the requirements of the individual application. We will present our work about a new Carbon nanomaterial called Aerographite which has the lowest density of all materials yet known (density < 0.2 mg/ccm) but is still mechanically robust and highly flexible. The foam like hierarchical 3D network structure has been investigated by various methods like SEM, TEM, XRD and EELS and based on the results a growth model was developed. It will be reported about the synthesis of Aerographite and its potential to design the material in the desired manner for the individual application. Further on, measurements regarding the electrical conductivity and the mechanical tensile/compression behaviour will be discussed. Experimental results of an Aerographite electrical double layer capacitor will be elaborated in more detail.
