Tesla (TSLA) Stock: $4.3B Michigan Battery Plant Aims to Cut China Dependency

TLDR

• Tesla and LG Energy Solution have signed a supply agreement to build a $4.3 billion LFP battery cell plant in Lansing, Michigan.
• Production at the facility is expected to launch in 2027.
• The plant will produce lithium iron phosphate (LFP) prismatic cells to power Tesla’s Megapack 3 energy storage systems.
• The deal was confirmed by the U.S. Department of the Interior as part of the Indo-Pacific Energy Security Summit.
• LG Energy Solution stock closed up 4% on the news; Tesla stock dipped 0.4% in pre-market trading.

Tesla (TSLA) and South Korea’s LG Energy Solution have signed a supply agreement to build a $4.3 billion lithium iron phosphate (LFP) battery cell manufacturing facility in Lansing, Michigan. The U.S. Department of the Interior confirmed the deal on Monday as part of announcements tied to the Indo-Pacific Energy Security Summit.

Production at the new plant is expected to begin in 2027. The cells produced there will be used in Tesla’s Megapack 3 energy storage systems, which are manufactured in Houston.

Tesla, Inc., TSLA

Tesla has historically sourced batteries from Panasonic, China’s CATL, and its own internal production. LFP chemistry has long been dominated by Chinese manufacturers, and this deal marks a step toward building that capacity on U.S. soil.

LG Energy Solution is one of the few companies currently producing LFP batteries in the United States. That gives it a distinct advantage as EV and energy storage manufacturers look to diversify away from Chinese supply chains due to ongoing tariff pressure.

LFP batteries are generally seen as safer and longer-lasting than cobalt-based alternatives. They also tend to be cheaper to produce, which could help Tesla manage costs on its energy storage products.

Reuters first reported in July 2025 that LG Energy Solution had signed a $4.3 billion contract to supply LFP batteries globally over three years. At the time, LG Energy Solution didn’t name the customer or specify whether the batteries were for vehicles or storage systems.

LG Energy Solution Stock Jumps on Confirmation

LG Energy Solution closed 4% higher on Tuesday after the deal was officially confirmed. Tesla stock, by contrast, slipped 0.4% ahead of the U.S. opening bell.

The muted reaction from Tesla investors may reflect the broader pressure the stock has been under. Tesla has fallen 19% over the past three months, weighed down by concerns over slowing sales, weaker profits, and tighter margins.

The S&P 500 is down 1.7% over the same period, but Tesla’s decline has been steeper. Futures tracking the index were 0.4% lower on Tuesday as oil price moves added to market caution.

Production Timeline and Location

The Lansing, Michigan site will house the LFP prismatic battery cell operation, with the first cells expected to roll off the line in 2027. Tesla’s Megapack 3 units assembled in Houston will rely on that output.

The deal positions Tesla to reduce its dependence on Chinese battery imports at a time when tariffs have made that supply chain more expensive and less predictable.

LG Energy Solution confirmed the broader $4.3 billion supply contract last year, and Monday’s announcement officially ties that deal to Tesla and the Michigan location.
