Sodium Batteries Are Here — And Cheaper Than Anyone Expected

Lithium is rare, geographically concentrated, price-volatile, and can catch fire. Now imagine a battery that works almost exactly the same way but uses an element roughly 1,000 times more abundant, spread evenly across the whole planet, far cheaper, and much safer — sodium, the same sodium in table salt. For years sodium batteries were a lab curiosity. Now CATL and BYD are mass-producing them, and they turned out cheaper and better than almost anyone expected. In this episode of American Engineered, Jordan breaks down how sodium batteries work, why they're suddenly viable, where they beat lithium, and the honest limitation that means they won't replace it everywhere. 00:00 — The hook 01:00 — Why this matters 02:00 — How sodium batteries work and why they were hard 04:00 — Four breakthroughs that made sodium commercial 08:30 — Engineers in the chat 09:00 — The catches (energy density, maturity, LFP competition) 13:00 — My honest take 15:00 — Bottom line 🔧 Subscribe for weekly engineering breakdowns from a former aerospace and battery engineer. — — — Educational content.
