Specific Energy (Wh/kg) – The nominal battery energy per unit mass, sometimes referred to as the gravimetric energy density. Specific energy is a characteristic of the battery chemistry and packaging. Along with the energy consumption of the vehicle, it determines the battery weight required to achieve a given electric range.
This explains the specifications you may see on battery technical specification sheets used to describe battery cells, modules, and packs. Nominal Voltage (V) – The reported or reference voltage of the battery, also sometimes thought of as the “normal” voltage of the battery. Cut-off Voltage – The minimum allowable voltage.
Three related measures are capacity, specific capacity, and charge density. Capacity is measured in ampere hours or coulombs. (By definition, one ampere is equal to one coulomb per second.) It is a measure of the charge stored in a battery or fuel cell. Specific capacity is a measure of the charge stored per unit mass.
Specific energy is a characteristic of the battery chemistry and packaging. Along with the energy consumption of the vehicle, it determines the battery size required to achieve a given electric range. Power Density (W/L)
Power Density (W/L) – The maximum available power per unit volume. Specific power is a characteristic of the battery chemistry and packaging. It determines the battery size required to achieve a given performance target. Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously.
Specific power, or gravimetric power density, indicates loading capability. Batteries for power tools are made for high specific power and come with reduced specific energy (capacity).

One last metric: Specific Power# Like how Specific Energy is energy in terms of mass, Specific Power is power in terms of mass. It measures the amount of power provided by a power source, per unit of mass. Specific Power = Power / Mass We can also see this in terms of the parellel between Energy Density and Specific Energy.
