After 10,000 complete charging and discharging cycles, with a complete charge and discharge cycle per hour, these lithium-ion batteries still retain more than 85% of the initial capacity. This means that an electric car with those batteries could be fully charged every day for about 27.4 years and still be going strong. The power density of these batteries, which measures the available power per unit of weight, is also very high at 1,100 watts per kilogram. For an electric vehicle, this means short charging times and a superior acceleration capability.
