Seoul: LG Energy Solution Ltd. announced a breakthrough in its research on sulfur-based high-capacity batteries, revealing new possibilities for the technology previously hindered by short lifespan and instability. The South Korean battery manufacturer, in collaboration with Shirley Meng, a molecular engineering professor at the University of Chicago, has made significant strides in addressing the challenges associated with sulfur as a battery material.
According to Yonhap News Agency, sulfur's affordability and high-capacity potential have been limited by "polysulfide dissolution," a stability issue that degrades battery performance. To combat this, the research team implemented an all-solid-state battery structure utilizing a solid electrolyte in place of a liquid one.
In a statement, LG Energy Solution highlighted the significance of the research, noting that it opens up the possibility of expanding energy capacity beyond that of existing lithium-ion batteries. The research findings were published in the February edition of Nature Communications, an esteemed international scientific journal.
