Energy density


Amount of stored energy per unit volume.

Energy density is one of the indexes used for evaluation of the capability of energy supply means. The greater the energy density, the greater energy can be supplied from the smaller volume. Since the volumes of micromachines are small, raising their energy density is an important theme.
