Not until they actually make them "in volume". They could be ramping up volumes for years and years until they hit that price. When they start producing them, I would bet anything the initial run will not be $19/kWh.
Fair enough, I think that price is a while in the future but from another article:
>In the meantime, CATL’s rival BYD said that its sodium-ion batteries have made progress in reducing cost and are already on track to be on par with lithium iron phosphate battery cost next year and even 70% less in the long run. The Chinese battery maker broke ground on a 30 GWh sodium-ion battery factory earlier this year.
