Doosan Collaborates with China’s Top Precursor Company CNGR on Battery Recycling Materials

Doosan Enerbility's Battery Recycling Subsidiary
Signs Basic Agreement on Secondary Battery Material Recycling
Holds Eco-Friendly Technology Without Using Chemical Agents

Doosan Enerbility's battery recycling specialized subsidiary, Doosan Recycle Solution, established last year, is expanding its supply sources for raw materials in the battery recycling business.

Doosan Recycle Solution announced on the 29th that it has signed a Framework Agreement with China CNGR, the global number one in the precursor market, regarding the battery material recycling business.

Precursors are key materials that serve as raw materials for cathode materials in secondary batteries, with representative types including NCM (Nickel-Cobalt-Manganese), NCA (Nickel-Cobalt-Aluminum), and NCMA (Nickel-Cobalt-Manganese-Aluminum).

CNGR will supply secondary battery waste powder containing lithium, nickel, cobalt, manganese, etc., to Doosan Recycle Solution. Doosan Recycle Solution plans to recover lithium from the supplied waste powder and provide the remaining NCM raw material to CNGR.

The lithium recovery technology developed by Doosan Recycle Solution involves heat-treating secondary battery waste powder, separating lithium using pure water, and then recovering lithium carbonate or lithium hydroxide through crystallization technology. This technology has the advantage of being more economical due to a simpler process compared to existing technologies, is an eco-friendly method that does not use chemical reagents, and has improved lithium purity (over 99.5%) and recovery rate (over 85%).

Choi Jae-hyuk, CEO of Doosan Recycle Solution, said, "The technology developed by Doosan not only achieves a high lithium recovery rate but also results in low impurity content in the NCM remaining after lithium recovery, which is advantageous for CNGR as well. We expect that through this agreement, the two companies will satisfy each other's needs with their respective technologies and strengthen business competitiveness."

Doosan Recycle Solution plans to establish a commercial production facility in the Daegu National Industrial Complex by next year and start recovering lithium by processing about 3,000 tons of raw materials annually from 2026.
