Abstract

AbstractThe emergence of Li‐ion batteries provides a new path and scheme for carbon neutrality and carbon peak. The performance of lithium‐ion batteries is mainly determined by the electrode material. Among them, transition metal compounds have been widely studied in the anode and cathode materials of lithium‐ion batteries. Here, pure rare earth metal fluoride YF3 was synthesized by solvothermal method and subsequent calcination. The specific capacity of YF3 as a Li‐ion battery anode can increase from 29.3 mAh g−1 to 148.5 mAh g−1 after 1000 cycles at 0.1 A g−1, with a growth rate of up to 407 %. XPS and XRD tests confirmed that the lithium storage process was a typical conversion reaction. The successful application of YF3 in Li‐ion batteries provides a wider range for the selection of Li‐ion electrode materials and also provides a new idea for the exploration of new materials for lithium‐ion batteries.
