The lithium-ion battery separator (LiBS) utilization rate at SKIET, a subsidiary of SK Innovation specializing in display and battery materials, has been slow to recover, with the operation rate at the Jeungpyeong plant in South Korea hovering around 50% as of Q1 2023. This follows a year when the plant's utilization rate averaged only around 40%.
Yet, due to improved utilization rates at other global plants, the company's separator business logged an operating profit of $1.35 million in Q1, marking a return to surplus. SKIET’s company-wide performance for the period noted $107 million in. . .
