Polestar 5 battery deal with SK On

South Korean battery manufacturer SK On will supply battery cell modules for the forthcoming Polestar 5 electric four-door GT.

SK On became an independent company in October 2021 after South Korean energy company SK Innovation split off its battery business unit.

Polestar says it chose SK On due to its superior battery cell technology that offers high-performing chemistry, fast charging, efficient discharging and superior driving range.

The high-nickel battery cell modules comprise ultra-long 56cm cells with high energy density.

“Our relationship with SK On has been fruitful following our initial MOU and their investment in our brand,” says Polestar chief executive Thomas Ingenlath.

“Polestar 5 is developing at pace and will feature this high-capacity battery to provide the performance expected of our grand tourer.”

 SK On chief executive Jee Dong-seob says the latest agreement will create new opportunities.

Polestar 5 production is expected to start in 2025.
