What is the energy density of lithium battery?

  14250 280MAH 3.7V

  Energy density refers to the amount of energy stored in a certain unit of space or mass. The energy density of the battery is the electric energy released by the average unit volume or mass of the battery. The energy density of battery is generally divided into two dimensions: weight energy density and volume energy density.

  Battery weight and energy density=battery capacity × Discharge platform/weight, basic unit: Wh/kg

  Battery volume energy density=battery capacity × Discharge platform/volume, basic unit: Wh/L

  The greater the energy density of the battery, the more power stored in the unit volume or weight.

  The energy density of battery often points to two different concepts, one is the energy density of single cell, the other is the energy density of battery system.

  The cell is the smallest unit of a battery system. M electric cells form a module, and N modules form a battery pack, which is the basic structure of the vehicle power battery.

  The energy density of a single cell, as the name implies, is the energy density at the level of a single cell.

  According to Made in China 2025, the development plan of power battery is defined: by 2020, the battery energy density will reach 300Wh/kg; In 2025, the battery energy density will reach 400Wh/kg; In 2030, the battery energy density will reach 500Wh/kg. This refers to the energy density at the level of a single cell.
