Low-Cost Additive Powers Sodium-Ion Battery Beyond 2,000 Hours

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.

Low-cost additive powers sodium-ion battery beyond 2,000 hours

Researchers at the National University of Singapore have developed a safer solid-state sodium battery using a low-cost additive that improves ion movement and blocks dangerous metal growth inside the battery. The breakthrough targets one of the biggest challenges facing sodium-ion batteries: safety. While sodium is cheaper and far more abundant than lithium, most sodium batteries still rely on flammable liquid electrolytes that can leak or catch…

Safer all-solid-state sodium battery could cut grid storage costs and reduce lithium dependence

Lithium-ion batteries dominate the market for large-scale energy storage today. However, the element's uneven global distribution and rising costs are driving the search for alternatives. Sodium is roughly a thousand times more abundant in Earth's crust and can be extracted from seawater, making sodium-ion batteries a compelling option for grid-scale storage where cost and supply security are paramount.
