There’s a world of energy out there. Let’s make it last.

Within one generation, we must rid our societies of fossil fuels. The technologies of the past simply cannot power the future. For us, this means electrification – replacing fossil sources of energy with electricity. Electrification requires batteries, and batteries need separator film. This is where we come in.

Senior is a world-leading provider of separator film for the lithium-ion battery industry, enabling a green society supercharged by batteries.

We make batteries work, and we make electrification safe.

The future is electric.

Senior Material (Europe) AB has been awarded funding from Vinnova under the programme “Scaling up for a Sustainable Battery Value Chain 2026” for the project DCM-FreeSE – Sustainable Scale-Up of Dichloromethane-Free Battery Separators Manufacturing in Sweden. The project aims to accelerate the transition towards more sustainable battery manufacturing by eliminating the use of dichloromethane (DCM) in separator production and scaling up a safer, more environmentally sustainable manufacturing process. In collaboration with RISE and KTH Royal Institute of Technology, the project will advance DCM-free separator technology from pilot scale to pre-production level, while validating product performance and assessing environmental and industrial benefits. Through this initiative, Senior Material Europe contributes to strengthening a more sustainable, resilient, and competitive battery value chain in Sweden and Europe.
