US Start-Ups Bet on Sodium-Ion Batteries to Revive Domestic Manufacturing
A wave of American start-ups is pursuing sodium-ion battery technology as a path to US-made cells built from locally sourced materials.
A cluster of American start-ups is positioning sodium-ion battery technology as a potential solution to the United States' dependence on foreign-made cells, arguing that the chemistry can be produced domestically using materials sourced within the country.
Unlike conventional lithium-ion batteries, which rely heavily on lithium, cobalt, and nickel — minerals largely mined and processed abroad — sodium-ion cells use more abundant and geographically distributed inputs. Proponents say this structural difference could make domestic manufacturing both viable and cost-competitive.

The push comes as policymakers and industry leaders have grown increasingly concerned about the concentration of battery supply chains in Asia, particularly China, which dominates global cell production. Sodium-ion technology is seen by some in the sector as a way to sidestep that dependency without waiting for domestic lithium processing capacity to scale up.
Start-ups pursuing this path face significant hurdles, including proving their technology at commercial scale, securing financing, and competing against well-capitalized incumbents. Nevertheless, the combination of favorable policy signals and supply-chain anxiety has created an opening that entrepreneurs are moving to exploit.
