Energy density vs power density
Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery.This difference comes from batteries being

6 FAQs about [Energy storage density symbol]
What is energy density in energy storage?
In energy storage applications the energy density relates the mass of an energy store to the volume of the storage facility, 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 density of a fuel per unit mass is called the specific energy of that fuel.
What is the SI unit of energy density?
Its SI unit is kgm−3. What is the symbol of energy density? When comparing substances, it’s often more instructive to speak of their specific energy or specific work or gravimetric energy density or volumetric energy density (energy per mass) symbol e or w. or energy density (energy per volume) symbol u or η (eta) or ε (epsilon).
How is energy density expressed?
Energy density is generally expressed in two ways, although the first is more common: Volumetric energy density - how much energy a system contains in comparison to its volume; typically expressed in watt-hours per liter (Wh/L) or Megajoules per liter (MJ/L).
What is the total energy stored per volume?
The total energy stored per volume is the energy density of the electromagnetic wave (U), which is the sum of electric field energy density (UE) and magnetic field energy density (UB). What is energy density of photon?
What is a density of States in physics?
The density of states (DOS) is essentially the number of different states at a particular energy level that electrons are allowed to occupy, i.e. the number of electron states per unit volume per unit energy. What is energy density of a wave?
What is energy storage?
