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.

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.
