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.

In comparison, energy management, such as load shifting, requires systems of up to MWh or even GWh levels that are capable of discharge durations up to a few hours or more at designated power. 15 years) and a long cycle life (e.g.,
