Different recycling possibilities of Li-ion batteries (LIBs)

Blog Post created by Hassen Jaafar on May 15, 2020

It is possible to use classic pyrometallurgy processing to recover most of transition metals in the battery's electrode composition (Co, Ni, Cu, ...) but unlikely the Lithium or Aluminum which are generally getting burned since this process runs near a temperature of 1500 °C.

However, Chinese groups are using chemical leaching (less energy cost and running below 100 °C) to extract metals containing electrodes but the drawbacks of this method is the use of harmful solvents like strong acids (HCl, HNO3, H2SO4, ...) or hydrogen peroxide.

 

More highlights on this topic and the possible improve in LIBs recycling operations can be found in this recent article published by C&EN. It’s time to get serious about recycling lithium-ion batteries
