Abstract
An electrode suitable for use in energy storage devices is described which is made of an assembly of an electrically conductive carbonaceous material having conjugated and preferably polybenzenoid plate-like structures. The carbonaceous material has a Youngs modulus of greater than 1,000,000 psi. The so-defined electrode material does not undergo a substantial change in dimension during repeated electrical charge and discharge cycles. Additionally there is described an energy storage device utilizing the above described electrode.
