Battery technology is entering a transformative phase, with lithium-ion production expanding in the US yet still reliant on imports, while alternatives like solid-state, sodium-ion, and zinc-based batteries gain traction. Advanced modeling, flexible manufacturing, and chemistry-aware supply chains will define competitiveness, helping manufacturers innovate in energy storage, micro-mobility, and mission-critical applications.
How Did US Lithium-Ion Production Perform in 2025?
In 2025, US lithium-ion manufacturing made notable progress, growing from a few gigafactories in 2019 to roughly three dozen plants either planned, under construction, or operating. Despite this growth, North America faces a tens-of-gigawatt-hour shortfall, maintaining dependence on imports. Incentives like the Inflation Reduction Act have accelerated domestic expansion, yet global Li-ion capacity remains dominated by China.
What Emerging Battery Chemistries Are Gaining Momentum?
Solid-state, sodium-ion, and zinc-based batteries are the most promising alternatives:

-
Solid-State: Moving from lab-scale to pilot and early gigafactory deployments, offering higher safety and energy density.
-
Sodium-Ion: Accelerating fastest, with China expected to account for over 90% of global capacity by 2030; suitable for grid-scale storage.
-
Zinc-Based: Primarily used in stationary and long-duration storage, still a smaller market compared with Li-ion.
These technologies offer opportunities for US manufacturers to develop geopolitically aligned and diversified energy storage solutions.
How Should Manufacturers Adapt to New Chemistries?
Three strategic steps are critical:

-
Chemistry-Flexible Manufacturing: Standardize formats, pack architectures, and modular equipment to accommodate multiple chemistries without full plant redesign.
-
Digitize and Simulate: Use AI-driven models like Large Quantitative Models (LQMs) to test chemistries and process conditions virtually, predicting lifetime, safety, and performance before physical trials.
-
Chemistry-Aware Supply Chains: Shift sourcing from lithium, nickel, and cobalt toward sodium, iron, manganese, zinc, and aluminum, with multiple supplier qualifications and scenario planning.
What Implications Do Chemistry Shifts Have on Material Sourcing?
As chemistries move from nickel/cobalt to iron, manganese, phosphate, sodium, and aluminum, US manufacturers must optimize portfolios for cost, performance, and geopolitical resilience. Data-driven approaches using tools like LQMs enable co-optimization of cell performance and raw material risk while simulating duty cycles and temperature environments.
Where Are the Most Significant Opportunities in Sodium-Ion and Alternative Chemistries?
Four primary innovation lanes exist:
-
Grid-First Sodium-Ion Platforms: Long-life, abuse-tolerant packs for utilities and co-ops, especially in cold climates.
-
Allied Supply Chain Chemistries: Products using abundant, geopolitically aligned elements to qualify for domestic incentives.
-
Process and Manufacturing IP: Proprietary techniques in coatings, binders, formation, and recycling accelerated by AI models.
-
Application-Specific Architectures: Integrated turnkey solutions for micro-grids, telecom backup, and industrial UPS systems.
How Should Manufacturers Prepare for Lithium Price Shifts?
Stable or rebounding lithium prices require strategic preparation:
-
Chemistry Hedging: Maintain options in LFP, LMFP, sodium-ion, and zinc-based chemistries to adapt cost structures.
-
Material Efficiency: Optimize cell lifetime and usable kWh per kilogram of lithium using simulation-based degradation models.
-
Strategic Contracting: Combine long-term base supply contracts with flexible spot purchases and alternative chemistries.
What Advice Is Key for Diversifying Products Across ESS and Micro-Mobility?
-
Core Chemistry Platform with Variants: Optimize for both grid storage (life, cost) and micro-mobility (power, cold-cranking).
-
Segment by Duty Cycle: Cluster usage patterns to design cells and packs tuned for specific cycles, avoiding over-engineering.
-
Modular Packs and BMS: Standardized interfaces allow swapping chemistries or formats over time without full redesigns.
