Ioxus says that it is working on increasing the energy densities as well. both electrodes are carbon, as opposed to the hybrid (asymmetric) ultracapacitors in which in one of the electrodes is carbon and the other electrode utilizes a different material. Ioxus makes carbon-carbon ultracapacitors—i.e.,
