LITHIUM BATTERY RECYCLING PROCESS, APPARATUS, AND SYSTEM FOR THE PRODUCTION OF BLACK MASS
20230115052 · 2023-04-13 ·

A method of making black mass from lithium containing batterie includes the steps of closing a chamber enclosing lithium-containing batteries and injecting nitrogen into the chamber to create an atmosphere sufficiently low in oxygen to prevent explosions and burning of the lithium-containing batteries. The lithium-containing batteries are shredded in the nitrogen atmosphere to produce shredded batteries. The shredded batteries are heated in the nitrogen atmosphere to a temperature sufficient to vaporize electrolyte and plastics from the batteries and produce pyrolyzed fragments. Lithium is present in a water-soluble nitrate form within the pyrolyzed fragments. The pyrolyzed fragments are classified to produce a black mass and a remaining metals fraction. The remaining metals fraction can be further classified to recover ferrous metals, light metals, and heavy metals.
