Northern Battery Gigafactory Reaches Closed-Loop Recycling
A large battery plant in the north says it now feeds most of the nickel and lithium it recovers from scrap and used cells straight back into its own production lines. Here is why closed loops matter for supply chains.

Battery factories generate a surprising amount of scrap. Electrode offcuts, cells that fail quality checks and returned packs from early customers all contain valuable metals. In this illustrative launch-edition report, a large battery plant in the north says it has reached what it calls closed-loop recycling: most of the nickel, lithium and cobalt it recovers from that scrap, and from used batteries collected through a take-back program, now flows directly back into its own production lines.
The company reports a recovery rate of about 95% for key metals. That figure is self-reported and covers the plant’s own process; it has not been independently audited. Still, the development points to a broader shift in how the battery industry thinks about raw materials.
How the loop works
Recycling batteries generally involves several stages. Packs are discharged and dismantled, cells are shredded, and the resulting material, often called black mass, is separated into its components. The plant uses a hydrometallurgical process, dissolving metals in chemical solutions and then precipitating them out in purified form. Those purified materials are turned back into the precursor chemicals used to make new cathodes.
- Inputs: factory scrap, defective cells and end-of-life packs collected through take-back.
- Process: shredding, chemical leaching and purification on the same site.
- Output: cathode precursor materials used in the plant’s own new cells.
Keeping everything on one site cuts transport costs and emissions and lets the company control quality closely, which matters because battery materials must meet strict purity standards.
Why it matters for supply chains
Battery makers depend on a small number of mining regions and refiners for key metals, and prices have swung sharply in recent years. Each kilogram of metal recovered on site is a kilogram that does not have to be bought on that volatile market. Over time, as more electric vehicles reach the end of their lives, recycled material could become a significant share of supply.

The limits of the loop
Closed loop does not mean the plant no longer needs mining. Today, the volume of batteries reaching the end of their lives is still small compared with the volume of new batteries being made, because the electric vehicle market is growing fast and most packs last many years. For the foreseeable future, recycled metal can only cover a portion of demand. The company has not said what share of its total raw material needs recycling currently meets, which is the number that would show how much difference the loop makes.
Recycling also has its own footprint. Hydrometallurgical processes use chemicals and energy, and they produce waste streams that must be treated carefully. The plant says it runs largely on renewable electricity and treats its process water on site, but it has not published detailed environmental data.
Collection is the hard part
Getting used batteries back is often harder than processing them. Packs end up in scrap yards, are exported in second-hand vehicles, or are repurposed for home energy storage. The plant’s take-back program offers carmakers and fleet operators a credit for returning used packs, and a regional logistics network handles collection. Officials in the region are considering rules that would require producers to take responsibility for batteries at the end of their lives, which would make collection more systematic.
What is not yet known
Besides the recycled share of supply, it is unclear how the economics of the loop hold up when metal prices fall, since recycling becomes less attractive when fresh raw material is cheap. The quality of recycled cathode material over many generations of recycling is also still being studied, though early results across the industry are encouraging.
What to watch next
Watch for an independent audit of the recovery rate, disclosure of the share of raw material supplied by recycling, and the progress of producer-responsibility rules in the region. If those pieces fall into place, closed-loop plants like this one could become a standard part of the battery industry, making it less dependent on distant mines and the swings of commodity markets.
