The watt-hour per kilogram ( symbol: W⋅h/kg) is a unit ofcommonly used to measure the density ofinand .Wh/kg is a unit of specific energy used to measure the density of energy in batteries and capacitors12. It is measured in watt-hours per kilogram and is equal to 3600 joules per kilogram in the SI system of measurement1. Li-ion batteries provide the highest density of up to 250-270 Wh/kg for commercially available batteries, while lead-acid batteries offer less than 100 Wh/kg and nickel metal hydride batteries reach barely over 100 Wh/kg2.

As the photovoltaic (PV) industry continues to evolve, advancements in Wh kg battery have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
