SK IE Technology— a subsidiary of SK Innovation— is planning to invest $200 million to expand its separator plant in Poland from 433 million square meters to 1.54 billion square meters.
The investment is part of the 1.13 trillion won ($800 million) investment in the Polish plant, which was approved by the company’s board of directors in March last year, according to news outlet Business Korea.
Separators directly affect the safety and performance of lithium-ion batteries and account for up to 20% of battery costs.
SK first announced plans for the Polish plant in 2019, to manufacture lithium-ion battery separators (LiBS) and ceramic coated separators (CCS) for electric vehicle batteries in Europe.
The South Korean group broke ground on the plant site in Województwo Śląskie in southern Poland in the third quarter of 2019— and began mass production in the third quarter of 2021.
