LG Energy Solution and Seoul National University Advance Next-Generation LMR Battery Commercialization

LG Energy Solution and Seoul National University have made significant progress toward the commercialization of lithium manganese-rich (LMR) batteries. A joint research team has successfully suppressed gas evolution, a major hurdle that has previously hindered the widespread adoption of this battery technology.

The newly developed technology was applied and optimized for large-format cells with a 40-ampere-hour (Ah) capacity. In experimental testing, these cells retained 92.2 percent of their initial energy capacity after 883 charge cycles, indicating a substantial improvement in battery durability and lifespan.

LMR batteries offer higher energy density compared to conventional lithium-ion batteries, positioning them as a promising candidate for applications such as electric vehicles and energy storage systems. The ability to control gas evolution is critical for ensuring the safety and performance of these batteries, and overcoming this challenge unlocks new potential for advancements in battery technology.

This research addresses the growing demand for more efficient and long-lasting battery solutions. The collaboration between LG Energy Solution and Seoul National University is poised to drive further development in the battery market and accelerate the transition to sustainable energy.
