Ultium Cells retrofits Tennessee plant for LMR cell production

Ultium Cells, a GM and LG Energy Solution joint venture, plans to retrofit a Tennessee plant to produce lithium-manganese-rich (LMR) cells by 2028. The company claims LMR cells offer 33% higher energy density than LFP at similar costs. GM aims to use these cells in future EVs, with a focus on pickups and large SUVs. The project aligns with GM's battery strategy shift, potentially phasing out LFP for vehicles. Investments may reach $1 billion by 2030, creating 500 jobs.
