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.
Specific energy (Wh/kg) – The energy a battery can store per unit of mass. Energy density (Wh/L) – The energy a battery can store per unit of volume. Power density (W/kg) – The power a battery can deliver per unit of mass. Cycle life – The number of charge/discharge cycles a battery can handle before it loses a lot of capacity.
Energy density is very important for battery performance. It affects how big and heavy a battery can be. More energy density means batteries can be smaller and lighter. This is great for making thinner phones, longer-range electric cars, and more efficient drones. It also helps make batteries cheaper by needing less material.
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.
The conversion factor (1000) changes the capacity from milliampere-hours to watt-hours, standardizing the units for energy calculations. The Battery Energy Density Calculator helps by calculating the gravimetric (Wh/kg) and volumetric (Wh/L) energy density of batteries.
