Apr 8, 2025 - Why the Biggest Battery Company is Betting Against Lithium



Why the Biggest Battery Company is Betting Against Lithium. Sodium-ion battery technology isn`t exactly new, but something interesting is happening. CATL, the world`s biggest lithium battery manufacturer, says that up to half the market could switch to sodium. That`s right—the biggest name in lithium batteries is betting against lithium. Looks like lithium might need to recharge its reputation. After all, sodium-ion batteries are nearly as good lithium, and salt is much cheaper and easier to access than lithium. So maybe its not surprising that CATL and some other companies are getting ready to manufacture huge numbers of them in preparation for what could be a massive market shift. But is sodium really the future of energy storage, or is it just another battery technology destined to live in lithium-ion`s shadow?
