As always another journalist
As always another journalist only mentions a negative aspect of sodium ion batteries - their still relatively low energy density. The same was repeated ad nauseam about LFP(Lithium Iron Phosphate) batteries. But thanks to China's rapid innovators(BYD, CATL etc) over half of Tesla's Model 3's and Model Y's for instance are now LFP-powered - and all offer EPA ranges over 270 miles. And sodium ion cells offer other major advantages - they are for instance very heat-stable and can typically be charged from 20%-80% in 15-30 minutes. They can also operate at extreme cold-hot ambient temperatures - from -30C to +50C. And of course sodium is extremely cheap and ultra-abundant compared to lithium. One cubic metre of seawater for instance contains 35kg of salt/sodium chloride..the world's oceans contain trillions of tonnes of it.
