If you’re in the market for a new battery or simply curious about the types of batteries available, you may have come across the term “energy density” before. Energy density is a measure of how much energy a battery can store per unit of weight or volume. The higher the energy density, the more power the battery can provide for its size.

The energy density of AA batteries varies depending on the type of battery. Alkaline AA batteries, which are the most common type of AA battery, have an energy density of around 100-150 Wh/kg. Lithium AA batteries, on the other hand, have a much higher energy density, with some models reaching up to 300 Wh/kg.
Power density is the amount of power (time rate of energy transfer) per unit volume. For energy conversions, including batteries, fuel cells, motors, power supply units, etc., power density refers to a volume, where it is often referred to as volume power density and is expressed in W/m³ or W/L.
Lithium-ion batteries accounted for the largest volumetric energy density among energy storage devices. Energy density is a measure of the amount of energy that a battery can contain in comparison to its volume. Similarly, gravimetric energy density, or specific energy, compares the energy contained in a battery in comparison to its weight.
There is a “volumetric energy density”, sometimes short-abbreviated as “energy density” and the specific energy density also called as the gravimetric energy density. Therefore, the amount of energy per kg (Wh/kg) or the amount of energy per litre (Wh/L).
