SK ie technology Ceases Commercial Production at Jeungpyeong Plant for Battery Separators... Shifts to Poland Hub for Efficiency, Short-term Sales Decline Expected


  • SK ie technology decided to cease commercial operation of all lithium-ion battery separator production lines at its Jeungpyeong plant in Chungbuk, an early production base.
  • The reason for the stoppage is deteriorating profitability due to aging facilities (15 years of operation), low utilization, and declining economic viability. The company made this decision as part of global production base efficiency improvement.
  • The Jeungpyeong plant's recent sales were approximately 117.7 billion KRW, accounting for 44.96% of total sales (approximately 261.9 billion KRW). On a separate basis, the discontinued segment's sales proportion is 68.3%, making short-term sales decline inevitable.
  • To ensure supply stability, the company will sequentially adjust production operations and plans to replace capacity with its Poland production base (approximately 1.5 billion sqm). This is expected to reduce fixed costs related to the Jeungpyeong plant and improve operational efficiency.
  • The planned suspension date is November 30, 2026, and specific plans for facility and site utilization will be disclosed upon finalization.
  • [AI Comprehensive Analysis]This production halt is essentially a restructuring move to close an aged domestic plant and transfer production to a new plant in Poland. While it may negatively impact sales and utilization in the short term, it is expected to contribute to fixed cost reduction and global efficiency improvement in the long term, making it a neutral event for shareholder value.
