US Startups Chase Sodium-Ion Batteries to Rival China
US start-ups are attempting to establish domestic production for sodium-ion batteries, a technology viewed as a cheaper and safer alternative to lithium-ion. While current products rely on Chinese cells, firms like Unigrid, Peak Energy, and Emerald Battery Labs aim to build US supply chains to meet rising demand from data centers and grid storage. Experts note that while sodium-ion offers cost and safety advantages, it remains less energy-dense than lithium-ion, limiting its use in small devices.
