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.
