  "account": "LG Energy Solution has made progress toward bringing lithium manganese-rich (LMR) batteries to the market for electric vehicles by uncovering the causes of gas generation and capacity loss in these next-generation power sources. Collaborating with researchers from Seoul National University, the South Korean firm found that stabilizing large-format LMR cells hinges on controlling both charging and discharging voltage ranges. Published in the prestigious scientific journal Nature Communications, the team's work underscores the technology's potential while highlighting the engineering challenges it faces when scaling up for EV applications. LMR batteries present an attractive alternative to cobalt-heavy cathodes, using cheaper manganese. However, inconsistencies in oxygen renewal during charging and discharging can cause gas buildup, structural damage and shortened battery life. The researchers determined that both high and low voltage limits need to be optimized. Lowering peak charging voltage from 4.6 volts to 4.3 volts increased oxygen recovery from 86% to 97%. Discharging to 2.0 volts instead of the typical 3.0 volts also helped restore much of the cathode's original oxygen content. Armed with these insights, LG Energy Solution redesigned the voltage profile and formation protocol for 40Ah-class large-format LMR cells. Operating at lower temperatures during cell manufacturing also curbed gas formation. After 883 charge-discharge cycles, these enhanced batteries retained 92.2% of their original capacity, a notable milestone for large-scale EV applications. The breakthrough demonstrates that LMR's promise extends beyond the lab to the real world of electric vehicles. As automakers and battery makers push for cheaper, high-energy-density power sources, the company's work could bolster LMR's commercial viability.",
