» Electrical » Battery Energy Density Calculator The Battery Energy Density Calculator provides crucial metrics for battery manufacturers, designers, and end-users by calculating the gravimetric (Wh/kg) and volumetric (Wh/L) energy density of batteries.
Higher energy densities mean a battery can store more energy relative to its size and weight, which is crucial for enhancing the performance and portability of devices. Can the energy density of a battery change over time?
Currently, the lithium-air battery has the highest theoretical energy density, at around 11,400 Wh/kg. However, this battery is still in the research and development stage and has not yet been commercialized. Among commercial batteries, the lithium-ion battery has the highest energy density, with some models reaching up to 265 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.
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.
