Requirements for hydrometallurgy
(odnośnik otworzy się w nowym oknie)
Chemical and physical characterization of feed material obtained from WP1, which consists of anode rich and cathode rich black mass, will be done. WP3 will specify the maximum purities required for hydrometallurgical process. Preliminary leaching test will be part of the characterization of feed material. The test results will be used as feedback in separation and grading process performed by WP1. This deliverable will be a result of Tasks 3.1 – 3.3.
Requirements for grading process
(odnośnik otworzy się w nowym oknie)
Development of grading processes for active material into high grade (as feed for direct recycling process) and low grade (as feed for hydrometallurgical process). The target of developed grading process as 40% of output material is classified as high grade. This deliverable will be a result of Tasks 1.2 – 1.6.
Requirements for direct recycling.
(odnośnik otworzy się w nowym oknie)
Direct recycling scheme from used battery active material will be developed, in which the target includes preservation of the active material structure. Optimization of the scheme will be based on the performance of active material produced, safety and commercial viability. This deliverable will be a result of Tasks 2.1 – 2.5.
