China’s Senior Technology Material is investing SEK 2.5bn (about £206m) to build a lithium-ion battery separators production plant in Sweden – to supply the gigafactory being developed by Northvolt.

Shenzhen-based Senior said the plant in Eskilstuna, the global separator supplier’s first production line investment outside China, is set to become its European headquarters when construction is completed in 2025.

Senior plans to establish a 70,000 sqm facility by 2025. Initially, the company will rent a 13,900 sqm facility at the Svista industrial estate in Eskilstuna, about 110 km east of Stockholm, to start its phased construction process.

Senior’s chairman, Xufeng Chen, said: "Europe will be the world’s most important market for the electrification of transport and energy storage solutions in the future.”

'Great potential'

"The market opportunities are vast and there is great potential for further development. Senior’s establishment of a production facility in Sweden is a key step in our global strategy.”

Products will be transported by rail from Eskilstuna to the Northvolt Ett battery cells manufacturing plant at Skellefteå, which is about 800 km north of the Swedish capital.

Northvolt Ett has a potential annual production capacity of 40 GWh and is scheduled to start production this year.
