Definitive roadblocks en route the mass adoption of electric vehicles (EVs) are battery range and life. Longer ranges lower recharging anxiety at a time when the web of battery swapping and/or charging stations is not widespread. Repeated rapid charging lowers battery life [1]. Swapping throws up complex battery ownership issues, EV range depends mainly on how much electricity the battery can store and, secondarily, on the rate at which it consumes electricity. With a 520 miles range, the Lucid Air Dream Edition is the electric car with the longest range at present [2].
