Energy density - Energy Education

Gravimetric energy density - how much energy a system contains in comparison to its mass; typically expressed in watt-hours per kilogram (Wh/kg), or Megajoules per kilogram (MJ/kg). Gravimetric energy density can also be referred to as specific energy. Having a high energy density does not give information on how quickly this energy can be used.

Energy density vs power density - Energy Education

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.

Energy Density Formula with Examples - BYJUS

Energy Density is defined as the total amount of energy in a system per unit volume. For example, the number of calories per gram of food. Foodstuffs that has low energy density provide less energy per gram of food which means that you can eat more of them since there are fewer calories. It is denoted by letter U.
