Northvolt Revolt

Believe in resurrection

The world needs clean batteries. And a plan for what to do with them at end-of-life. Our solution: take old batteries and turn them into fresh raw materials for batteries of tomorrow.

What goes out. Comes back in.


Others cherry-pick copper and aluminum. We recycle almost everything into new batteries.

Yearly capacity

Europe's largest battery recycling plant is being built at Northvolt Ett.

Reused input

We'll source half of the raw materials for new cells from recycled cells by 2030.

Making without taking

Step 1


Before anything else, we discharge batteries of all energy to make them safe to recycle. Where possible, energy will be recovered to power later steps in the recycling process.

Step 2


The next step in the recycling process involves removing modules from the packs that arrive to us. For this, we use robots to unscrew, cut, lift and perform any other operations required to reach the modules and cells. 

Step 3

Crushing & Sorting

This is our mechanical process step, and it begins with crushing and shredding the batteries. The material is then processed using a variety of techniques to separate fractions of metals and plastics. Electrolyte is also isolated and recovered. The remaining material is the most valuable – a fine powder we call black mass. 

Step 4


Black mass is a powdered mixture of metals which we must purify to recover materials that can be used in the production of fresh batteries. To do this, we use a hydrometallurgical ‘hydromet’ treatment.
