The regenerated ternary cathode material precursor synthesized by the co-precipitation method was roasted with lithium carbonate at a molar ratio of 1:1.1, and then completely mixed with different contents of aluminum hydroxide. The combined materials were then sintered at 800 \u00b0C for 15 h to obtain the regenerated coated cathode material, LiNi0.8Co0.15Al0.05O2@x%Al2O3. The thermogravimetry analysis, phase composition, morphological characteristics, and other tests show that when the added content of aluminum hydroxide is 3%, the regenerated cathode material, LiNi0.8Co0.15Al0.05O2@1.5%Al2O3, exhibits the highest-order layered structure with Al2O3 coating. This material can better inhibit the production of Ni2+, and improve material structure and electrochemical properties. The first charge\u2013discharge efficiency of the battery assembled with this regenerated cathode material is 97.4%, a 50-cycle capacity retention is 93.4%, and a 100-cycle capacity retention is 87.6%. The first charge\u2013discharge efficiency is far better than that of the uncoated regenerated battery.<\/jats:p>","DOI":"10.3390\/molecules28135165","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T00:53:16Z","timestamp":1688345596000},"page":"5165","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Preparation and Performance of Regenerated Al2O3-Coated Cathode Material LiNi0.8Co0.15Al0.05O2 from Spent Power Lithium-Ion Batteries"],"prefix":"10.3390","volume":"28","author":[{"given":"Liwen","family":"Ma","sequence":"first","affiliation":[{"name":"Collaborative Innovation Center of Capital Resource-Recycling Material Technology, Faculty of Materials and Manufacturing, Beijing University of Technology, Beijing 100124, China"},{"name":"National Engineering Laboratory for Industrial Big-Data Application Technology, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangyun","family":"Liu","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Capital Resource-Recycling Material Technology, Faculty of Materials and Manufacturing, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuehua","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Functional Materials, Ministry of Education, Faculty of Materials and Manufacturing, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Xi","sequence":"additional","affiliation":[{"name":"Collaborative Innovation Center of Capital Resource-Recycling Material Technology, Faculty of Materials and Manufacturing, Beijing University of Technology, Beijing 100124, China"},{"name":"Key Laboratory of Advanced Functional Materials, Ministry of Education, Faculty of Materials and Manufacturing, Beijing University of Technology, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"145913","DOI":"10.1016\/j.scitotenv.2021.145913","article-title":"Management status of waste lithium-ion batteries in China and a complete closed-circuit recycling process","volume":"776","author":"Sun","year":"2021","journal-title":"Sci.
