Lithium-ion batteries have been critical to the electrification of our grid and transportation, but their cost, low Earth-abundance, and supply chain security remain areas of concern.

Sodium-ion is a promising alternate chemistry, but falls short on energy density. With the PowerNaP anode, sodium-ion achieves its full potential. Our novel phosphorus anode material brings sodium-ion energy density up to par with lithium-ion, at up to 50% cost savings.
