October 10, 2025: California-based lithium sulfur developer Lyten has put a new management team in place in Sweden and Poland for Northvolt, in the wake of its takeover of the troubled European battery maker.
Batteries International reported last August that Lyten had moved to acquire Northvolt’s remaining assets in Sweden and Germany, after Northvolt filed for bankruptcy in Sweden.
Lyten has since revealed that it appointed a new executive team on September 4 to support the takeover.
Matthias Arleth has been named CEO of Lyten Sweden, based in Stockholm and reporting to Lyten CEO Dan Cook.
Arleth is a senior industrial executive and engineer with more than 25 years of international leadership experience across the automotive, energy, and electronics industries, Lyten said.
He joined Northvolt one year ago as president BU Cells and COO, where he was instrumental in the restructuring process in Sweden and successfully improving production performance at the firm’s Skellefteå facilities.
Meanwhile, Robert Chryc Gawrychowski will serve as CEO of Lyten Poland, based in Gdansk, also reporting to Cook.
He will lead the Northvolt Dwa BESS operations, including the systems organization responsible for BESS product design, after being with Northvolt Poland since its launch.
Markus Danglemaier will be CEO of Northvolt Ett, in Skellefteå, reporting to Arleth.
Sami Haikala was confirmed as CEO of Northvolt Labs, in Västerås, Sweden, also reporting to Arleth. He has headed the plant since 2022 and will be responsible for both lithium ion NMC product enhancements and work with Lyten’s San Jose team to accelerate lithium sulfur development.
Dennis van Schie has been named chief supply chain officer for Lyten Sweden, based in Stockholm and reporting to Arleth. Lyten said he has nearly three decades of experience in the automotive, electronics, and chemical industries.
Lyten said all members of the team had been pivotal in stabilizing operations and delivering to customers over the last year.
Lyten CEO Cook said: “We have the ingredients to be successful in Sweden, Poland, and Germany. This is a team that knows how to execute. They each have a proven track record in industry and collectively drove a step change in manufacturing performance in Skellefteå over the last year.”
