PROCESS FOR PREPARING AND RECYCLING CATHODE ACTIVE MATERIALS FOR LITHIUM-ION BATTERIES |
| 摘要 |
Herein is disclosed a process for preparing a cathode active material for lithium-ion batteries, comprising preparing a slurry by mixing a lithium-deficient cathode active material for lithium-ion batteries with a solution containing lithium-ions; and applying a direct current in the slurry using a working electrode and a counter electrode. A method for recycling the cathode active material from lithium-ion batteries is also provided. The process of the invention can be used to recycle the cathode active material from used or waste lithium-ion batteries efficiently and at low cost, and the recycled cathode active material can be used to prepare new lithium-ion batteries. |
