Abstract
A very high energy-density ultracapacitor apparatus and method includes more than one carbon electrode with an outer surface and an inner surface. A conductive metallic surface is connected with the outer surface. A ceramic is connected with the inner surface of at least one of the more than one carbon electrodes. A separator is provided between the more than one carbon electrode and an electrolyte is provided.
Claims22
