1

Raw Materials Mining

Primary raw materials are extracted globally, either from open-pit or underground mines.
Once extracted, the raw materials are crushed into smaller pieces and then milled into a fine powder.

2

Processing

The raw materials are refined and purified through chemical processing, where controlled chemical reactions transform the materials into high-purity compounds suitable for battery production.

3

Precursor/Cathode Active Materials Production

Refined materials are processed into precursor cathode active material (PCAM) through controlled chemical reactions. Lithium is then added, followed by high-temperature treatments, to produce cathode active material (CAM) with optimized electrochemical properties.

4

Battery Cell & Pack Production

CAM is integrated into electrode manufacturing, where it is coated onto metal foils to form battery electrodes. These electrodes are then assembled with anodes, separators, and electrolytes in a controlled environment to create battery cells.

5

End Users

Finished battery cells are integrated into applications like electric vehicles, consumer electronics, and energy storage systems, powering end users' everyday needs.

6

Recycling (Black Mass)

Used batteries are collected and processed to extract valuable materials. This involves shredding them into 'black mass,' a powder containing lithium, nickel, and cobalt (subject to battery chemistry) which is then refined for reuse in new batteries.
