This value is then just divided by the volume of the cell to calculate volumetric energy density or divided by the mass of the cell to calculated the gravimetric energy density. Perhaps the simplest of the battery metrics as the capacity of the cell is fairly easy to measure and the mass is just a set of scales.
To aid understanding, below is a table of key terms related to battery energy density calculations: The amount of energy a battery can store relative to its mass or volume. Energy per unit mass (Wh/kg). Energy per unit volume (Wh/L). The total electrical charge a battery can hold, measured in milliampere-hours.
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?
If you want an excel based set of calculators please check out the Battery Calculations Workbook. The Faraday Institution has developed a cell calculator called CAMS capable of modelling the energy density experimental cell designs. CAMS was designed to rapidly assess the potential energy density of different cell chemistries and cell formats.
