In short:

Key quote:

“Our product can have millions of cycles, where lithium-ion would have three to five thousand cycles and wear out a lot faster.”

— Wendell Brooks, co-CEO of Natron Energy

Why this matters:

Sodium-ion batteries could address the environmental toll of lithium mining while offering a stable, cost-effective solution for large-scale energy storage. While less efficient for compact devices, their durability and lower costs make them an appealing alternative for renewable energy grids.
