Battery black mass recycling
Black mass recycling is a process that extracts valuable materials like lithium, manganese, cobalt, nickel, and other materials from used lithium-ion batteries. These materials are essential for manufacturing new batteries and can be carefully extracted, processed, and reincorporated into new batteries. However, since their natural supply is limited, extracting them from untouched sources is environmentally damaging.
As the adoption of electric vehicles surges, there’s an escalating demand for metals such as cobalt and lithium. These minerals are predominantly found in select regions of the world such as the Democratic Republic of Congo, one of the largest global cobalt producers, while countries like Argentina, Chile, and Australia lead in lithium production. These specific geographies make minerals scarce and prone to supply chain disruptions due to political, environmental, or economic factors.
Before restrictions, many companies in Europe and North America were exporting large quantities of black mass to China for processing because it was cheaper to process there. China had a large market for importing this material for recycling. With environmental concerns, they have significantly restricted black mass imports over time, classifying it as hazardous waste.
On December 31, 2024, China issued its first national standard for black mass material used in lithium-ion battery recycling formally named GB/T 45203-2024 Black mass for lithium-ion battery. It will take effect July 1, 2025, according to China’s national public service platform for standards information. The new standard will categorize black mass into two types: type 1 being black mass produced from lithium-ion batteries containing nickel and cobalt, and type 2 being made from lithium iron phosphate (LFP) batteries.12
Currently, the largest importers of black mass are in South Korea, Southeast Asia, and India, but demand in all three locations has decreased over the last few months. Black mass is expected to gradually find its way into battery production, pending quality checks and qualifications; consequently, black mass will be part of digital passport requirements.
