In energy storage and fuels. 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.
The batteries that Tesla uses in their electric cars deliver about 254 W⋅h/kg, [1] compared to supercapacitors that are typically rated between 3 and 10 W⋅h/kg, [2] with the best commercially available supercapacitors as high as 47 W⋅h/kg.

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
[2] [4] [1] Li–S batteries offer specific energies on the order of 550 Wh/kg, [1] while lithium-ion batteries are in the range of 150–260 Wh/kg. [5] Li–S batteries with up to 1,500 charge and discharge cycles were demonstrated in 2017, [6] but cycle life tests at commercial scale and with lean electrolyte have not been completed. As of ...

The term "lithium battery" refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode. The battery requires from 0.15 to 0.3 kg (5 to 10 oz) of lithium per kWh. As designed these primary systems use a charged cathode, that being an electro-active ...
Volumetric energy density = 220 Wh/L (790 kJ/L) Gravimetric energy density > 90 Wh/kg [31] (> 320 J/g). Up to 160 Wh/kg [1] (580 J/g). Latest version announced in end of 2023, early 2024 made significant improvements in energy density from 180 up to 205 Wh/kg [32] without increasing production costs.
