GM to mass-produce next-generation LMR batteries, targets 33 percent more range at LFP cost
General Motors has chosen Spring Hill, Tennessee, as the mass-production base for next-generation lithium manganese-rich (LMR) batteries for electric vehicles. It plans to produce the batteries at Ultium Cells, its joint venture with LG Energy Solution, and start plant upgrades later this year, finishing by 2028. GM said the plant will be the first to mass-produce prismatic LMR cells and that the technology can boost driving range by 33 percent versus LFP batteries.

LG Energy Solution, Seoul National University solve gas generation in LMR batteries
LG Energy Solution and Seoul National University said they have addressed a key hurdle to commercialising lithium manganese-rich (LMR) batteries by curbing gas generation in large cells for electric vehicles. The team analysed oxygen redox behaviour during charging and discharging and found that both upper charge voltage and lower discharge voltage affect oxygen recovery. Using redesigned operating and activation conditions, a 40Ah-class LMR large cell retained 92.2 percent of initial energy after 883 cycles.

LG Energy Solution first global battery maker to top 100,000 patent applications
LG Energy Solution has become the first battery company to surpass 100,000 patent applications globally, the company said on Saturday. As of last month, it had about 59,000 registered patents and more than 100,000 patent applications. It said it invested 1.33 trillion won in R&D last year after first exceeding 1 trillion won in annual R&D spending in 2023, and cited patents spanning materials, electrode design, cells, packs, BMS and manufacturing.
