LG Energy Solution and Seoul National University Open the Door to Commercializing Next-Generation LMR Batteries
The optimized 40 Ah-class cells retained 92.2% of initial energy after 883 cycles, supporting large-format EV commercialization.
- On Sept 7, LG Energy Solution and Seoul National University announced a joint study breakthrough led by Professor Jongwoo Lim, improving the stability of LMR batteries for large-format EVs.
- Gas generation and capacity degradation hindered LMR battery commercialization when oxygen redox reactions during charging cycles damaged internal structures in space-constrained large-format cells for EVs.
- Researchers improved stability by lowering charging voltage to 4.3 V from 4.6 V and discharge voltage to 2.0 V from 3.0 V, while applying lower-temperature formation processes; optimized 40 Ah-class cells retained 92.2 percent energy after 883 cycles.
- The findings, published in Nature Communications, demonstrate that optimized electrochemical protocols effectively suppress gas evolution, proving the feasibility of applying LMR technology to large-format cells for EVs.
- By utilizing low-cost manganese instead of cobalt, this next-generation cathode material offers a cost-effective alternative for EVs, providing a foundation for expanding LMR battery commercialization beyond small-format applications.
