1. An electrode for an energy storage device, the electrode comprising:
a conductive layer;
an active layer of energy storage media substantially free from binding agents and comprising a matrix of carbon nanotubes defining void spaces and binding carbonaceous material in the void spaces; and
an adhesion layer being substantially free of binder material and disposed between the active layer and the conductive layer;
wherein the matrix of carbon nanotubes comprises a concentration of carbon nanotubes that exceeds a percolation threshold thus causing the electrode to exhibit electrical connectivity within the active layer;
wherein the matrix of carbon nanotubes is less than 1% by weight of the active layer; and wherein the carbon nanotubes comprise aligned carbon nanotubes.
