How could General Motors' shift to LMR chemistry affect LG Energy Solution?

Possible What happens if… A possibility worth considering, not a forecast.

GM's shift to LMR chemistry may require LG Energy Solution to adapt its Ultium Cells joint venture. General Motors is developing Lithium Manganese-rich (LMR) chemistry to reduce its reliance on Chinese Lithium Iron Phosphate (LFP) supply chains. The reports confirm that GM plans to build these LMR batteries with LG Energy Solution at their Ultium Cells joint venture in Spring Hill, Tennessee. This shift requires LG Energy Solution to adapt its technical scope and production processes to support LMR, which offers 33% more energy density than LFP, while still meeting GM's goals for volume production starting in 2028.

The facts so far

As reported. Each one links to where it comes from.

  • LMR chemistry offers 33% more energy density than LFP.fortune.com
  • GM plans to build LMR batteries with LG Energy Solution at their Ultium Cells joint venture in Spring Hill, Tenn.fortune.com
  • LFP is the cheap chemistry China dominates.fortune.com
  • The LMR battery won’t reach volume production until 2028.fortune.com

Why it matters

For LG Energy Solution, the partnership with General Motors is a significant component of its global battery manufacturing footprint. The shift to LMR chemistry represents a major technical pivot, requiring the company to adapt its production lines and technical expertise within the Ultium Cells joint venture to support this new, higher-density chemistry.

This move by General Motors is part of a broader industry trend toward supply chain diversification. By developing LMR, GM is actively seeking independence from the dominance of Chinese LFP supply chains, a strategic move that impacts how global automakers structure their partnerships and technology development.

What we don't know yet

  • How quickly can LG Energy Solution scale up production of LMR chemistry at the Ultium Cells joint venture?
  • What specific technical challenges does the transition from LFP to LMR chemistry present for the joint venture?

What would change this answer

GM accelerates the LMR battery timeline before 2028This would increase the immediate pressure on LG Energy Solution to rapidly implement and validate the LMR production process.
GM seeks additional battery partners for LMR developmentThis could dilute LG Energy Solution's role in the LMR supply chain, potentially reducing the scope of the Ultium Cells joint venture.
