Lithium ion batteries: energy density?
Today''s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries'' energy densities doubling
Recent advances in lithium-ion battery technology have pushed gravimetric energy density to new heights. Researchers in China have developed lithium-ion batteries with energy densities exceeding 600 Wh/kg, which is double the current best commercial batteries.
You encounter two main types of energy density when evaluating lithium-ion batteries: specific energy density and volumetric energy density. Specific energy density measures the energy stored per unit mass (Wh/kg), while volumetric energy density refers to energy stored per unit volume (Wh/L).
A 1 kWh lithium-ion battery typically weighs around 6.7 kg, whereas a lead-acid battery of the same capacity can weigh approximately 25 kg. This substantial weight difference makes lithium-ion batteries more suitable for applications where weight is a critical factor, such as in electric vehicles and portable electronics.
You select lithium-ion battery chemistry based on the required energy density, weight, and application. NMC batteries deliver high energy density (150–220 Wh/kg), platform voltage of 3.7 V, and cycle life of 1000–2000 cycles. These batteries suit electric vehicles and robotics, where high energy density and low weight improve range and agility.
