Delivering value through recovered materials and process innovation.
At Li-Cycle’s Spokes, lithium-ion batteries of all formats, chemistries and states of charge are processed through a mechanical process. This process breaks down the batteries to inert materials that minimize the risk of fire or explosion, and subsequently separates the resulting materials into two main product lines: battery materials (black mass) and mixed copper/aluminum.
Battery materials (black mass)
The Spoke produces a product that consists of a mix of cathode and anode battery materials, including lithium, nickel and cobalt, as well as graphite, copper and aluminum.
The Spoke produces copper and aluminum metals from the processing of lithium-ion batteries. These are primarily made up of the foils found within the lithium-ion batteries.
At Li-Cycle’s Hub, battery materials (black mass) are run through the hydrometallurgical circuit to produce individual metal sulphate and carbonate products with the purity levels required to be used in cathode and precursor production. By re-inserting the Hub products back into the lithium-ion battery supply chain, Li-Cycle effectively closes the loop between the end-of-life and manufacturing phases in both an environmentally and economically sustainable manner.
High purity, micronized lithium carbonate derived from end-of-life lithium-ion batteries. Suitable for use in many applications including lithium-ion and lithium polymer batteries, as well as glass and ceramics manufacturing.
High purity cobalt sulphate derived from end-of-life lithium-ion batteries. Suitable for the production of cobalt containing cathode materials for lithium-ion and lithium polymer batteries.
High purity nickel sulphate derived from end-of-life lithium-ion batteries. Suitable for the production of nickel containing cathode materials for lithium-ion and lithium polymer batteries.
High purity manganese carbonate derived from end-of-life lithium-ion batteries. Suitable for use in many chemical applications.
