One of the World's Top EV Separator Producers
SK IE Technology (SKIET), a battery material subsidiary of SK Innovation, announced on April 13 that it has started operating its second LiBS plant in Changzhou, China.
SKIET’s first plant in China started operations in November last year. The company can now produce separators needed for 500,000 electric vehicles annually in China alone. When the production capacities of its plants in Korea and Poland are included, SKIET’s total capacity amounts to one million units of separators a year. The company is planning to expand its capacity to three million units a year by 2024.
Separators are a key material for electric vehicle batteries. They are the No. 1 cause of electric vehicle fires. However, not one single fire has occurred from batteries loaded with separators from SKIET.
SKIET's separators go into batteries for Tesla, Volkswagen, Renault Nissan, Toyota, Hyundai Motor and Kia. In terms of market shares of wet separators in 2020, SKIET came in first in the world with a 26.5 percent share.
