EV battery costs have declined significantly over the past ten years, from more than $1,000 per kilowatt-hour (kWh) to less than $200/kWh. Increasing cell energy is one way to decrease cost even further, as a higher specific energy value will result in fewer materials needed for the same total battery energy. Earlier post.).
