Geographically, the Mideast region commands the largest market share at 16.4%, while the Southeast and New England regions are growing at 14.2% and 13.3% respectively over the forecast period, reflecting the geographic spread of new manufacturing investments.

• •Lithium-ion cells growing at 16.2% CAGR, the fastest technology segment
• •Mideast region holds the largest share at 16.4% of the national market
• •Southeast and New England showing solid growth at 14.2% and 13.3% CAGRs respectively

Who are the notable companies in the industry?

The U.S. cell manufacturing landscape is in a transitional phase, shifting from a historically import-dependent supply chain toward a domestically concentrated production base. The competitive structure spans fully integrated producers that control cell assembly and upstream material processing, alongside specialty manufacturers focused on niche formats and end-use applications. Capacity is being concentrated in the Southeast and Mideast, where large-scale greenfield facilities are clustering near automotive assembly hubs and logistics infrastructure.

• •Market transitioning from import reliance toward domestic integrated cell manufacturing capacity
• •Competitive tiers include vertically integrated producers with upstream material operations and specialty-focused manufacturers
• •New gigafactory capacity is concentrating in the Southeast and Mideast regions near automotive and logistics clusters

What are the recent trends and outlook?

Looking ahead, the convergence of EV mandates, grid decarbonization targets, and continued federal support is expected to sustain the 14.3% growth trajectory through 2035. Process innovation is advancing toward higher-energy-density chemistries and simplified manufacturing routes to reduce per-cell costs. Simultaneously, the build-out of a domestic cathode and anode material supply chain is reducing reliance on imported inputs, which should improve both the resilience and cost competitiveness of U.S.-made cells over the forecast horizon.

• •EV and storage mandates combined with policy support are expected to sustain double-digit growth through 2035
• •Process improvements and chemistry advances aim to lower manufacturing costs and improve energy density
• •Domestic upstream material supply chains are developing, reducing import dependency and enhancing sector resilience
