Energy Density refers to the amount of electrical energy that a battery can store per unit volume or unit mass. It is one of the core indicators for measuring the thinness and endurance capacity of batteries, and is usually expressed in the following two forms:
Gravimetric Energy Density (质量能量密度): Energy per unit mass, unit: Wh/kg
Volumetric Energy Density (体积能量密度): Energy per unit volume, unit: Wh/L
Cautionary Notes:
The increase in energy density often comes with the risk of reduced safety and decreased cycle life.
In practical applications, a balance must be struck between energy density, lifespan, power, and safety.
