A quiet shift in power is taking place across the global battery industry.

After more than three decades of lithium dominating smartphones, laptops, and electric vehicles, China is bringing a technology once left behind back into the race: sodium-ion batteries.

With CATL leading the charge, sodium is gaining attention for its lower cost, strong performance in extreme cold, long lifespan, and the potential to greatly reduce fire risks. Behind this progress are decades of hard carbon research, difficult material challenges, and a billion-dollar technology gamble.

In this video, Mandarin Tech explores the rise of sodium-ion batteries and how CATL is taking this technology from the laboratory to commercial production. Can “salt” really reshape the global energy map and force lithium to give up its throne?
