How could General Motors' development of LMR chemistry affect China?
GM's LMR battery development may reduce China's EV supply chain dominance General Motors is developing Lithium Manganese-rich (LMR) chemistry as an alternative to Lithium Iron Phosphate (LFP), the chemistry that China currently dominates. LMR offers 33% more energy density than LFP, allowing GM to reduce its reliance on Chinese LFP supply chains. GM plans to build these LMR batteries with LG Energy Solution at its Ultium Cells joint venture, and the company stated it is not licensing this technology from China.

How it reaches China
-
General Motors is developing Lithium Manganese-rich chemistry (LMR) for its next EV battery. This chemistry offers 33% more energy density than Lithium Iron Phosphate (LFP), which is the cheap chemistry dominated by China. The battery is not expected to reach volume production until 2028.
The full event1independent outlet -
By successfully implementing LMR, which GM plans to build with LG Energy Solution and which GM is not licensing from China, GM could reduce its purchasing volume of LFP batteries from Chinese suppliers, thereby weakening China's market leverage in the EV battery sector.
No report states this step directly. Brind drew it from the reporting on each side of it, so treat it as an informed guess.

Why it matters
The EV battery supply chain is a critical geopolitical and economic battleground, with China holding significant dominance in the LFP market. Any major Western automaker successfully developing a superior, non-Chinese alternative chemistry could fundamentally shift global supply dynamics and reduce the strategic leverage held by Chinese manufacturers.
This move by General Motors is part of a broader trend among US automakers seeking to de-risk their supply chains and meet government scrutiny regarding China links. The success of LMR, which GM believes has solved historical issues like short cycle life and voltage decay, is key to whether this shift in demand becomes a material factor for the global market.
What we don't know yet
- Will LMR chemistry achieve the necessary volume production to significantly impact the global market?
- How quickly can GM scale up LMR production compared to existing LFP supply chains?
