Density Calculator
Note that density is also affected by pressure and temperature. In the case of solids and liquids, the change in density is typically low. However, when regarding gases, density is largely affected by temperature and pressure. An increase in pressure decreases volume, and always increases density. Increases in temperature tend to decrease

Batteries with high theoretical energy densities
As expected, (CF) n /Li battery has a high practical energy density (>2000 Wh kg −1, based on the cathode mass) for low rates of discharge (<C/10) [63]. However, it is found that the power density of (CF) n /Li battery is low due to kinetic limitations associated with the poor electrical conductivity of (CF) n of strong covalency [64].

What is the 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.
What is the power density of a battery?
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).
What is the energy density of Mg/S batteries?
Assuming 1672 mAh g −1 cathode capacity and a mean discharge voltage of 1.77 V, these reactions deliver high theoretical gravimetric and volumetric energy density of 1684 Wh kg −1 and 3221 Wh L −1, respectively. The theoretical volumetric energy density of Mg/S batteries exceeds that (2856 Wh L −1) of Li/S batteries.
How do you calculate energy density?
Graphically, it is the area under the voltage vs. specific capacity curve. Someone calculate the energy density by multiplying the maximum capacity of the battery for the mid-point potential (Potential of the battery when it is discharged to 50% of its capacity).
How do you calculate gravimetric energy density?
The calculations are quite simple as the energy content of the cell [Wh] = V nom x Ah nom. 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.
How do you calculate a battery's usable energy?
In the simplest terms the usable energy of a battery is the Total Energy multiplied by the Usable SoC Window. The total energy is the nominal voltage multiplied by the nominal rated capacity.
