How CATL’s Reinforced Sodium Battery is Insanely Cheap

CATL have secretly been filing many patents - and I came across one that really caught my interest. I believe their new full scale approach towards sodium-ion (of course, alongside the lithium ion cells) is due to a breakthrough that will make their manufacturing a lot cheaper and easier!
