What is Energy Density?
Energydensity refers to the amount of energy stored in a certain unit of space or mass of matter. The energy density of a battery is the amount of electricity emitted by the average unit volume or mass of the battery. The energy density of a battery is generally divided into two dimensions: weight energy density and volume energy density.
Battery weight energy density = battery capacity × discharge platform/weight, the basic unit is Wh/kg (watt-hours/kg)
Battery volume energy density = battery capacity ×discharge platform/volume, the basic unit is Wh/L (watt-hours/liter)
The greater the energy density of a battery, the more power can be stored per unit volume or weight.
What is Monomer Energy Density?
The energy density of a battery often refers to two different concepts, one is the energy density of a single cell, and the other is the energy density of a battery system.
A battery cell is the smallest unit of a battery system. M cells form a module, and N modules form a battery pack, which is the basic structure of automotive power batteries.
The energy density of a single cell, as the name suggests, is the energy density at the level of a single cell.
According to the "Made in China 2025", the development plan of power batteries has been clarified: in 2020, the energy density of batteries will reach 300Wh/kg; In 2025, the energy density of the battery will reach 400Wh/kg; In 2030, the energy density of batteries will reach 500Wh/kg. This refers to the energy density at the level of a single cell.
