What is battery energy density?lithium ion golf cart batteries manufacture

　　Energy density refers to the size of the energy in a certain space or quality material. It is used to measure the battery that is most suitable for batteries and compares the unit volume of batteries. The energy density of the battery is also the power released by the volume or quality of the average unit of the battery. The energy density of the battery generally has two dimensions: weight energy density and volume energy density. The larger the energy density of the battery, the more power stored in the unit volume or the weight. Below is the formula of battery energy density calculation.

　　Battery weight energy density = battery capacity × discharge platform/weight, the basic unit is wh/kg (wattime/kg).

　　Battery volume energy density = battery capacity × discharge platform/volume, the basic unit is wh/L (watt -hour/liter).

　　Battery energy density is affected by battery materials, voltage platforms, production processes and other aspects. Therefore, if you want to increase the energy density of battery, you must start with battery size and chemical system.

　　According to the "Made in China 2025", the development plan of the battery is clear: in 2020, the battery energy density reaches 300WH/kg; in 2025, the battery energy density reaches 400WH/kg; in 2030, the battery energy density reached 500WH/kg. This refers to the energy density of a single battery level.
