Rapid commercialization and scaling of sodium-ion battery technology, particularly for stationary energy storage applications. Major battery manufacturers globally are investing heavily in sodium-ion production, touting its advantages such as lower material costs, improved safety characteristics compared to some lithium-ion chemistries, and abundant raw materials. As sodium-ion batteries scale to mass production and achieve competitive cost and performance targets, they present a direct, non-lithium alternative that could significantly compete with Eos Energy Enterprises' zinc-based technology in the grid-scale energy storage market.

Eos Energy Enterprises (NASDAQ: EOSE) specializes in zinc-based battery energy storage systems, including their flagship Eos Znyth® battery technology, which provides long-duration energy storage for utility-scale, commercial, and industrial applications.
