Summary:

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.

All-solid-state batteries offer a safer and more powerful way to run electric vehicles, power electronics, and store renewable energy from the grid. However, their key ingredient, lithium, is both costly and scarce, and mining it often causes serious environmental harm.

Sodium presents a much cheaper and more abundant alternative, and it is far less damaging to extract. Yet, sodium-based solid-state batteries have long struggled to match lithium's performance at typical temperatures.
