Why CATL and BYD Are STILL Betting on Sodium-Ion Batteries.

Sodium-ion batteries are back in the spotlight — but not for the reasons most people think. Sodium-ion chemistry has been written off for high-performance applications in the past, but new research reveals how ion transport and electrode design are transforming sodium-ion into a product that can genuinely challenge lithium-ion's dominance. Maybe that's why CATL and BYD are now accelerating real-world deployment despite lingering scepticism.
