The second life of battery materials
Battery recycling is a sequence of collection, processing and refining. A high recovery figure for one metal is not the same as recycling the whole battery without loss.
Canvas of Knowledge · 14 November 2026 · Illustrated explainerCHINA: BRUNP
CATL describes a circular supply chain through its Brunp subsidiary, linking battery use, recycling and material regeneration. Its reported recovery percentages refer to specified materials and processes.
NORTH AMERICA: REDWOOD
Redwood Materials describes separating and refining battery materials so they can return to manufacturing. The objective is battery-ready output, rather than simply collecting a heavy black powder.
COMPARE THE DENOMINATOR
Distinguish collection rate, process recovery, purity and recycled content. Repair, repurposing and material recycling are also different routes, chosen according to the battery’s condition and the available process.
THE IDEA TO KEEPThe loop closes only when recovered material becomes useful manufacturing input.
