A joint research team from LG Energy Solution and Seoul National University has cracked the most stubborn problem in next-generation EV battery chemistry — and done it without changing a single ingredient. Published September 7 in Nature Communications, the study identified for the first time that gas evolution in lithium manganese-rich (LMR) cells is controlled simultaneously by both the upper charging voltage and the lower discharge cutoff — a finding that produced 92.2% capacity retention after 883 full charge-discharge cycles in 40 Ah-class prismatic cells, the format used in commercial EVs. The announcement from LG Energy Solution's official press release came September 7, 2026. For anyone tracking the EV industry's transition away from cobalt-dependent batteries, this is the result that makes 2028 credible.
