Surrey, Canada based American Manganese Inc., has completed stages 1 and 2 of the Company’s lithium-ion battery recycling pilot plant operations which included the pre-treatment of feedstock material and a leach of the cathode active material.

“It is exciting to see our patent-approved process demonstrated on a pilot scale,” said Larry W. Reaugh, President and Chief Executive Officer. “The successful replication of the lab-scale operations in a larger continuous closed-circuit operation not only is the first step towards commercialisation, but also provides key evidence that the company’s lithium-ion battery recycling technology is economically sound.”

“The selected NMC-622 cathode feedstock, valued at US$16.25/kg, is processed at an estimated reagent cost of US$1/kg,” he added.

Kemetco, which provides scientific expertise in the fields of Specialty Analytical Chemistry, will continue to process select samples of cathode material feedstock as they prepare for the remaining stages of the pilot plant operations.

The complete five-stage Pilot Plant operation will progress as follows:

  • Stage 1 – Pre-treatment of cathode material
  • Stage 2 – Leach of active material
  • Stage 3 – Purification
  • Stage 4 – Recovery of base metals (e.g., nickel, cobalt, manganese)
  • Stage 5 – Lithium recovery and water recycle

With their increasing use by the automotive industry, the need to improve the recycling of lithium-ion batteries is becoming critical.

The Lithium Battery Recycling Challenge
Increasing oil prices, demand for urban vehicles, megacities and focus on sustainable transportation have kickstarted a substantial trend towards automotive electrification such as hybrids and electric vehicles (EVs). Estimates suggest that by 2020, EVs are likely to account for more than 7% of the global transportation market.
