  "account": "Seoul National University professor Lim Jong-woo, working with LG Energy Solution, has pinpointed a crucial factor causing gas formation and capacity degradation in lithium-manganese-rich (LMR) batteries, paving the way for the practical application of this advanced battery technology in large-format cells for electric vehicles (EVs). The research reveals that regulating oxygen reversibility during charging and discharging could enhance the stability of large-format LMR battery cells. LMR represents a promising next-generation cathode material, utilizing abundant and inexpensive manganese to achieve high energy density through oxygen redox alongside the redox of transition metals. However, the oxygen within the cathode often fails to revert fully to its original chemical state as the battery undergoes repeated charge-discharge cycles. This incomplete reversion leads to internal structural damage and gas buildup, presenting a significant challenge for large-format EV cells, which have limited space to absorb the resulting pressure. The research team meticulously examined oxygen redox behavior under various conditions.",
