SK On Co., the world’s fifth-largest electric vehicle battery maker, is set to increase its workforce for large-size cylindrical batteries with the 4680 form factor to meet demand from major EV makers such as Tesla Inc.
The South Korean battery maker is seeking experienced engineers and fresh doctoral graduates for the entire battery production process including cells, equipment, processes and components, according to industry sources on Sunday.
SK On is looking for experts on the 46-millimeter cylindrical cells, especially, as well as prismatic form factors, the sources said. The company has yet to limit the number of hires and the period of recruitment with plans to offer top-level salaries in the industry.
“Latecomer SK On is going all in to acquire talent despite a potential bloody talent war against competitors,” said an industry source.

IN TALKS WITH EV MAKERS
SK On, which established a task force in the second half of last year to develop a cylindrical battery, was reportedly in talks with EV makers on the production, industry sources said.
Chey Jae-won, executive senior vice chairman of SK On, confirmed last month for the first time that the company was developing the battery.
“We have made quite a lot of progress on cylindrical battery development,” Chey said on the sidelines of the Consumer Electric Show (CES) 2024, the world’s largest annual tech trade show in Las Vegas.
Tesla, the world’s No. 2 electric car manufacturer, is using 4680 cells made in-house for its vehicles but seeking to secure more from other suppliers as it increases EV production.
Some automakers, including BMW Group, General Motors Co. and Stellantis N.V. are gradually adopting the 4680 cylindrical type given its benefits.
