However, lithium-ion batteries defy this conventional wisdom. According to data from the U.S. Department of Energy, lithium-ion batteries can deliver an energy density of around 150-200 Wh/kg, while weighing significantly less than nickel-cadmium or lead-acid batteries offering similar capacity. Take electric vehicles as an example.
