The Ni[Formula: see text]Co[Formula: see text]Mn[Formula: see text](OH) 2 as the precursor of single-crystal NCM faces the issues of tedious preparation process and serious pollutant emission for traditional preparation methods during the industrial preparation. Herein, an improved continuous two-step spray pyrolysis strategy is adopted to prepare the precursor of single-crystal NCM. Combining with the industrial devices, ton-scale preparation of single-crystal NCM is realized after dynamic lithiation post-treatment. This improved strategy not only shortens the preparation process, but also reduces metal segregation and sintering temperature, effectively balancing the cost control and production efficiency. The samples sintering at 850[Formula: see text]C show uniform morphology with a diameter of 4.5 [Formula: see text] m and delivers an initial discharge capacity of 169 mAh/g at 0.1 C after 100 cycles. This work provides a new route for the industrial preparation single-crystal NCM cathode materials of LIBs.","PeriodicalId":12701,"journal":{"name":"Functional Materials Letters","volume":"12 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135728104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, MR fluid with composite and free-state SiO 2 were prepared. Composite magnetic particles of CIP@SiO 2 were synthesized using the sol-gel method with tetraethyl orthosilicate (TEOS) as the silicon source. Performance test results showed that CIP@SiO 2 MR fluid exhibited superior mechanical properties compared with CIP MR fluid under zero magnetic field conditions. However, under the influence of a magnetic field, the SiO 2 shell weakened the response of CIP@SiO 2 MR fluid to the magnetic field, whereas CIP MR fluid demonstrated better rheological properties. The addition of free-state SiO 2 to CIP MR fluid significantly improved its rheological performance. At a volume fraction of 6% SiO 2 , the shear stress and viscosity reached their maximum values, and further increasing the volume fraction to 8% resulted in a noticeable decrease in rheological behavior. Stability improved with an increase in magnetizable particle content. The stability of CIP MR fluid at the same concentration was superior to that of CIP@SiO 2 MR fluid, while free-state SiO 2 had a notable enhancing effect on stability. Therefore, when SiO 2 exists as a free-state abrasive, the rheological properties and stability of the MR fluid considerable improve.","PeriodicalId":12701,"journal":{"name":"Functional Materials Letters","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136233165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
