Are any batteries made in USA?
Yes, multiple U.S.-based companies manufacture batteries domestically, particularly for automotive and industrial applications. Leading manufacturers include Johnson Controls-Saft, A123 Systems, and EnerDel, with production facilities in states like Michigan and Indiana. Tesla operates a Gigafactory in Nevada producing lithium-ion batteries for EVs. The U.S. battery industry is accelerating investments—$100 billion planned this decade—to build localized supply chains, reducing foreign dependency while creating 350,000 jobs.
Understanding the Difference Between UN3480 and UN3481 for Lithium Batteries
Which U.S. companies produce lithium-ion batteries?
A123 Systems and Tesla dominate U.S. lithium-ion production. A123’s Michigan plants focus on high-power cells for EVs, while Tesla’s Nevada Gigafactory targets 150 GWh annual capacity. Pro Tip: These facilities prioritize NMC and LFP chemistries for energy density and thermal safety.
Lithium-ion battery manufacturing in the U.S. centers on automotive and grid storage applications. A123 Systems, backed by DOE loans, specializes in nanophosphate lithium-ion cells with 2.5-3.6V operating ranges and cycle lives exceeding 2,000 charges. Tesla’s 4680 cell design achieves 5x energy capacity improvements through dry electrode technology. For instance, Tesla’s Nevada factory supplies batteries for 500,000 EVs annually. However, material sourcing remains a bottleneck—70% of lithium and cobalt still rely on imports. Transitionally, companies are adopting localized cathode production to mitigate supply risks.
What about lead-acid battery production?
Johnson Controls and Exide Technologies lead U.S. lead-acid manufacturing, primarily for automotive starters and backup power. Facilities in Ohio and Pennsylvania utilize recycled lead (85% recovery rates) to meet 60% of domestic demand.
Despite lithium-ion growth, lead-acid retains 40% of the U.S. battery market. Johnson Controls’ Toledo plant produces 12.5 million units annually, emphasizing AGM (Absorbent Glass Mat) technology for start-stop vehicles. These batteries deliver 500-800 CCA (Cold Cranking Amps) with 3-5 year lifespans. Exide’s Kansas facility specializes in industrial batteries, including 2V cells stacked for 48V telecom backups. For example, a 200Ah lead-acid bank powers cell towers for 8-12 hours during outages. However, environmental regulations require sealed designs to prevent acid leakage. Practically speaking, U.S. manufacturers now invest $20/unit in closed-loop recycling systems to comply with EPA standards.
| Type | Energy Density | Lifespan |
|---|---|---|
| Lead-Acid | 30-50 Wh/kg | 3-5 years |
| LiFePO4 | 90-160 Wh/kg | 8-10 years |
How significant are U.S. government initiatives?
The DOE’s $2 billion ATVM loan program and Inflation Reduction Act tax credits drive domestic production. These incentivize 50% local content requirements for EV batteries by 2027.
Federal policies aim to reshore 80% of battery manufacturing by 2030. The Inflation Reduction Act offers $45/kWh tax credits for U.S.-assembled packs, effectively reducing Tesla’s Model Y battery costs by $3,800. The DOE’s $3.5 billion Battery Manufacturing Grants fund facilities like Redwood Materials’ Nevada cathode plant, targeting 100 GWh annual output. But what about raw materials? Projects like Lithium Americas’ Thacker Pass mine will supply 60,000 tons/year of lithium carbonate, covering 25% of domestic demand. Pro Tip: Companies combining IRA credits with state-level R&D grants achieve 18-22% cost reductions versus standalone investments.

FAQs
No—while cells are assembled in Nevada, 70% of raw materials like lithium and graphite remain imported. Tesla aims for 50% localized sourcing via Texas lithium refining by 2025.
Are U.S.-made EV batteries competitive globally?
Currently 15-20% costlier than Chinese equivalents due to labor and energy expenses. IRA subsidies narrow this gap to 5-8% post-2026.
