Cheaper than lithium, just as powerful — Sodium batteries are finally catching up

Researchers discovered how to stabilize a high-performance sodium compound, giving sodium-based solid-state batteries the power and stability they’ve long lacked. The new material conducts ions far more efficiently and supports thicker, energy-dense cathodes. Because it relies on a proven technique, it’s also easier to scale up for real-world use. This could bring safer, cheaper, greener batteries much closer to reality.
