If the average discharge voltage of the battery is 3.7 V, we can calculate the energy density as follows: Wh/kg energy density = (10 Ah * 3.7 V) / 1 kg = 37 Wh/kg Wh/L energy density = (10 Ah * 3.7 V) / 0.2 L = 185 Wh/L It is important to note that the energy density of a lithium-ion battery varies greatly depending on the battery and its design.
Referring to the battery terms, Battery energy density is the amount of energy that can be stored in a battery given a specific weight and volume. The higher the energy density, the better a battery is able to store energy. The battery’s voltage, charge capacity and discharge capacity determine its energy density.
A lithium-ion battery’s energy density can be affected by a number of factors. These factors include the type and purity of the materials used in the battery, the design of the battery cell, and the battery’s operating temperature.
Due to its high energy and power density, lithium ion batteries have become widely used in mobile devices such as laptops, cell phones etc. The energy density of lithium-ion batteries can be increased by using different cathode materials, electrolytes and separators resulting in enhancement of power density as well.
The method for calculating a battery’s specific energy or energy density is as follows: Nominal Battery Voltage (V) x Rated Battery Capacity (Ah) / Battery Weight (kg). It’s possible to calculate the specific energy of an individual cell, but the calculation requires knowledge of the actual cell dimensions and geometry.
To calculate the energy density in watt-hours per liter (Wh/L), use the following formula: (Capacity (Ah) * Voltage (V)) / Volume = Energy density (Wh/L) (L) The battery voltage is the average voltage of the battery during discharge in this case. This value varies depending on the battery and its state of charge.
