This latest cash call came after the company was listed on the South Korean stock exchange last year followed a pre-initial public offering (IPO) funding round which raised KRW2.25trn from investors including BlackRock, Qatar Investment Authority and a group of local investors.

Sources suggest SK On had not yet decided how much it would raise and which funding method to use. The funds would be used to invest in new factories, mainly overseas.

The company had four plants under construction in the US, in deals with Ford and Hyundai, while capacity was being expanded in South Korea and China.

SK On was also reportedly considering making larger 4680 type cylindrical battery cells to help meet growing demand from EV manufacturers for more energy dense and efficient cells. According to local reports, the company had begun a recruitment drive in South Korea to establish a new production operation for such cells.
