According to the company, sodium-powered heavy trucks showed around 15% lower energy consumption per kilometre compared with lithium-ion equivalents, while deeper discharge capability enabled roughly 20% longer range under typical conditions. The company stated that these results indicate that sodium battery heavy trucks have moved from technical validation into early-stage commercial application.
So “efficiency” means “range” and it’s a confluence of multiple factors that allegedly allow sodium batteries to use more of the power they store and use their power more efficiently. The article notes that sodium batteries are still more expensive than lithium-ion, but pretty much every major EV maker on China has R&D programs on them at the moment, leading to speculation that the costs will converge around 2027 and allow this battery technology to take over commercially.
I skipped the video and went straight to the source article

That’s pretty impressive
