The power density of a battery is a measure of how fast the battery can deliver energy. In other words, you can equate it to the maximum current that can be drawn from a battery of a given size. It is calculated by dividing the amount of power delivered by the battery ( Vo × Io ) with its mass (kg). PD = ( Vo × Io ) / ( kg )
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.
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?
In terms of volume, power density would be the output power processed by the system ( Vo × Io ) divided by the rectangular area of the circuit board (in case of a semiconductor) given as ( L × W ) multiplied by the height ( ×H ) of the tallest component on that circuit board. This can be expressed mathematically as: PD = ( Vo × Io ) / ( L × W × H )
It is just a matter of integrating the cell voltage vs. capacity curve and dividing it by the mass of active material. To obtain the value in the desired units (Wh/kg), the voltage should be in Volts and the capacity in Ah. Hope this helps.

While energy density measures how much energy a battery can store, power density determines how fast the stored energy can be released. In practice, batteries with a high energy density can store a lot of energy but may not deliver it rapidly. Conversely, those with a high power density can deliver energy quickly but may not hold as much. Hence, the "energy density vs power …
