LG-GM venture upgrades US plant for EV batteries

Ultium Cells, a joint venture between LG Energy Solution and General Motors, will upgrade its Tennessee plant to produce lithium manganese-rich (LMR) batteries, offering 33% higher energy density than LFP batteries at a comparable cost. The $1 billion investment by 2030 will create 500 jobs and expand the plant's output for EVs and energy storage. LMR batteries use less expensive metals like cobalt, helping reduce costs. Production is expected to start in 2028.

Ticker impact

$GMBullishHigh confidence
Context

GM's Ultium Cells joint venture will upgrade its Tennessee plant to mass‑produce new LMR batteries, a first in the world.

Expected impact

likely upward pressure as investors price in improved battery supply and cost advantages

Evidence & confidence

The $1 billion investment and first‑of‑its‑kind production are material for GM's EV rollout.

Market effects

Strengthens US EV battery supply chain, may boost broader EV and energy‑storage sectors.
