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. However, it is difficult to increase the energy density beyond that of today’s cells, which are approximately 220 Wh/kg using graphite anodes.
