| Abstract: |
| As a secondary resource, waste lithium batteries have big recovery value. Thermogravimetric analysis was used to determine high temperature destruction temperature characteristics of various battery materials through differential thermal analysis of lithium battery dismantling materials one by one. On this basis, pyrolysis test of waste lithium batteries was carried out. The results show that good pyrolysis results can be obtained by pyrolysis at 400 ℃, and black powder recovery rate is >97%. |
