Energy density is the key technical criterion for energy storage. The energy density consists of both the energy stored per unit mass or per unit volume of the energy storage medium. Carbon-based chemicals are very high in both areas.
The volumetric energy storage density is the amount of heat that can be released per volume unit of either the sorbent material (hereafter marked Qmat) or the whole system (Q sys, i.e. including the reactor and all the components for the management of air flow, in atmospheric systems, or of vapour and heat transfer fluids, in pressurized systems).
Storage energy density is the energy accumulated per unit volume or mass, and power density is the energy transfer rate per unit volume or mass.

For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.
High energy storage density means that more electric power can be stored in dielectrics per unit volume. Dielectrics are broadly classified into linear and nonlinear dielectrics based on the relationship between electric displacement (D) and applied electric field (E) .
Energy density is the amount of energy stored in a region of space per unit volume or mass. It is usually desirable that the energy density stored in an LIB system is as high as possible. The unit of energy density is Wh/kg, which is calculated by: where E is the voltage (V) and Q is the specific capacity (Ah/kg).
