General Motors is betting heavily on sodium-ion batteries—a chemistry that remains lab-stage at scale—as its path to materially cheaper EVs within five years, a timeline that requires simultaneously solving manufacturing, supply chain, and performance challenges that competitors haven't cracked yet. This is a commitment of capital and engineering, not a hedge. GM views incumbent lithium-ion supply chains as a bottleneck to mass-market EV adoption, not a solved problem. The risk is binary: if sodium-ion scales as promised, GM gets a 2-3 year cost advantage; if it doesn't, the company has burned $900M on an R&D bet while competitors continue incrementally improving lithium economics.
