Tesla signs $4.3 billion battery deal with LG and reduces reliance on China, report says

Tesla and LGES sign historic deal

Tesla has signed a $4.3 billion contract with LG Energy Solution. The deal will provide lithium-iron phosphate batteries made in the United States.

These batteries will be produced at LGES’s factory in Michigan for Tesla’s energy storage systems. The agreement aims to cut Tesla’s reliance on Chinese imports affected by tariffs.

Supply timeline confirmed

The contract will run from August 2027 through July 2030. LGES confirmed the agreement includes an option to extend for up to seven more years.

This flexibility gives both companies room to adapt to changing market needs. The deal forms part of Tesla’s strategy to strengthen U.S. battery supply for storage products.

Focus on energy storage systems

InsideEVs reported that the batteries will be used for Tesla’s energy storage products like Powerwall and Megapack. The agreement does not cover batteries for Tesla’s electric vehicles at this time.

This focus reflects Tesla’s growing energy division as a business priority. It also helps the company diversify beyond vehicle sales during shifting market conditions.

Why LFP batteries are chosen

The lithium iron phosphate batteries have lower energy density than other chemistries. However, they are known for better safety, longer lifespans, and lower manufacturing costs.

These qualities make them suitable for stationary storage instead of vehicles. Producing them in the U.S. also helps Tesla avoid tariff-related cost increases from Chinese imports.

Michigan production advantage

LGES began producing lithium-iron phosphate batteries at its Michigan plant in May 2025. This positions LGES as one of the few U.S. producers in a field long dominated by Chinese companies.

The plant location allows Tesla to secure a tariff-proof battery supply. It also supports domestic manufacturing growth within the United States.

Tariffs drive change in sourcing

Tesla’s Chief Financial Officer, Vaibhav Taneja, said in April that U.S. tariffs have had an “outsized” impact on its energy business, according to Reuters. Most lithium-iron phosphate batteries for Tesla are currently sourced from China.

The LGES deal directly addresses this challenge by shifting to a U.S. supplier. It marks a deliberate move to diversify sourcing.

Contract value and scale

The $4.3 billion deal between Tesla and LGES equals about a quarter of LGES’s yearly sales. This shows the scale of Tesla’s battery needs in the energy storage sector.

The agreement could grow in value and length if both parties agree. That potential reflects the rising importance of large-scale energy storage solutions.

Global demand for storage batteries

LGES plans to increase sales of storage batteries due to surging demand from data centers. These facilities require large amounts of power to train artificial intelligence models.

Energy storage systems help stabilize the supply for such high-demand operations. Tesla’s agreement with LGES fits into this broader growth trend in global energy needs.

LGES first-mover advantage in U.S.

Samsung Securities analyst Cho Hyun-ryul told Reuters that LGES is currently the only company producing LFP batteries at scale in the United States. Rivals like Samsung SDI and SK On have plans but have yet to begin production.

This early start gives LGES a competitive lead in the domestic market. Tesla benefits by securing supply from this position.

Vehicle applications remain possible later

Yahoo Autos reported that while the batteries are intended for energy storage now, future vehicle uses could be considered. Lithium iron phosphate batteries are cost-effective and suitable for budget-friendly EV models.

Tesla has explored producing more affordable versions of its vehicles. Such developments could eventually align with the availability of Michigan-made LFP batteries.

Reducing supply chain risks

Tesla recently signed a $16.5 billion semiconductor supply agreement with Samsung Electronics. Similar to the LGES battery deal, this arrangement focuses on production within the United States.

Both agreements aim to secure critical components from domestic facilities. Together, they represent a deliberate effort by Tesla to diversify and stabilize its global supply chain.

Tesla energy’s role in company revenue

In FY2024, Tesla’s energy generation & storage business produced $10.1B (10%) of total revenue; in late-2024/2025 quarters, it hovered around 12–14%. Despite representing a smaller portion, this segment has recorded growth in recent quarters.

The division includes products like Powerwall and Megapack. The LGES agreement is expected to provide additional supply for this expanding business area.

EV demand slowdown impacts production plans

LGES is considering converting some U.S. electric vehicle battery production lines to produce storage batteries. This consideration follows reports of slower demand for electric vehicles.

The change would allow the company to meet rising needs for stationary energy storage. Such production adjustments align with ongoing shifts in the global battery market.

Affordable EV trends could benefit LFP use

Tesla is developing a more affordable Model Y version intended for wider markets. Lithium iron phosphate batteries are generally more cost-effective than other chemistries.

This characteristic makes them suitable for lower-priced vehicle models. However, there has been no announcement regarding the use of LGES’s Michigan-produced LFP batteries in Tesla’s electric vehicles.

Ford, GM, and Nissan have adopted Tesla’s charging plug. A move expected to influence EV charging infrastructure and compatibility standards.

Energy Storage as a Stabilizer

Tesla’s energy division is regarded as a stabilizing segment within the company’s operations. The agreement with LGES ensures a steady supply of lithium-iron phosphate batteries manufactured in the United States.

This arrangement limits exposure to import-related costs and potential supply chain interruptions. The contract directly supports one of Tesla’s fastest-growing business segments, energy generation and storage.
