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.
This is the calculation formula of energy density of lithium secondary batteries: Energy density (Wh kg −1) = Q × V M. Where M is the total mass of the battery, V is the working voltage of the positive electrode material, and Q is the capacity of the battery.
Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery.
This pioneering battery exhibited higher energy density value up to 130 Wh kg −1 (gravimetric) and 280 Wh L −1 (volumetric). The Table 1 illustrates the energy densities of initial rechargeable LIBs introduced commercially, accompanied by the respective company names .
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.
In order to achieve high energy density batteries, researchers have tried to develop electrode materials with higher energy density or modify existing electrode materials, improve the design of lithium batteries and develop new electrochemical energy systems, such as lithium air, lithium sulfur batteries, etc.
A good energy density for a battery depends on what it will be used for. For example, if you''re using a battery to power a small device, such as a remote control, a lower energy density may be sufficient. However, if you need a …
