Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells

"American-made cells will power Tesla's Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain. Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027."

"Tesla has long utilized China's Contemporary Amperex Technology Co. (CATL), the world's largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that's particularly reliant on LFP cells for products including its Megapack battery storage units."

"For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On."

Tesla and LG Energy Solution are expanding their partnership to construct an LFP prismatic battery cell manufacturing facility in Lansing, Michigan, with production beginning in 2027. The U.S. Department of the Interior officially confirmed Tesla as the stakeholder in this $4.3 billion battery supply agreement. American-made cells will power Tesla's Megapack 3 energy storage systems produced in Houston, establishing a domestic battery supply chain. This partnership addresses Tesla's need for tariff-compliant, domestically produced batteries as Chinese import tariffs increase and Tesla Energy's reliance on LFP cells grows. LG Energy Solution becomes the only major supplier currently scaling U.S. LFP production, positioning itself ahead of competitors like Samsung SDI and SK On.
