Sodium-ion batteries have arrived. Even now less than half the costs of lithium batteries, and much longer lifespans. An EV battery using sodium chemistry would run for well over 5 million km (yes MILLION), and still have more than 85% of its life after that time. It will revolutionise energy everywhere, not just in cars. Super cheap batteries with enormous storage and lifespan. Join the revolution. You don’t get those often, don’t miss it.
