A comparison of lithium-ion battery feedstocks

Recovery of metals using electrochemical leaching
Recovery of metals using electrochemical leaching

This research was performed by CMI scientists at Idaho National Laboratory with CMI Team member Retriev.

Achievement

  • We have demonstrated that our EC leaching process efficiently leaches feedstocks with variable compositions.

Significance and impact

This demonstrates EC leaching is robust for various waste feedstocks including a cobalt rich and nickel-rich feedstock.

  • Further proof to justify effectiveness of EC leaching method
  • With demonstrated robustness, we can move forward to optimize process for time and iron sulfate addition

Details and next steps

  • Produce pure metals for Y7 milestones
  • Test recovered graphite in new LIB batteries
  • Evaluate AZR feedstock and demonstrate recovery pathway
