electricity) to hybrid and electrical vehicles, although the cost of implementing EES is of great concern. This type of application requires high round-trip energy efficiency and a long deep-cycle life, along with low operation and maintenance costs. Among the most important factors are capital cost and life-cycle cost.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

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. Energy densities of hybrid ultracapacitors can be significantly greater than that of carbon-carbon ultracapacitors, but power densities are lower.
