| Abstract | In this study, we synthesized a bimetal hydroxyl fluoride, Co0.6Zn0.4(OH)F, with an overlapping nanoneedle structure using a simple hydrothermal method. The synthesized Co0.6Zn0.4(OH)F was used as a new electrode material to study its electrochemical performance. Because of the synergy between Co and Zn and the high ionicity of fluorides, the Co0.6Zn0.4(OH)F electrode exhibited a discharge capacity of 1355.5 mAh g(-1) during the first charging and discharging cycle. After 400 cycles at a current density of 2 A g(-1), the Co0.6Zn0.4(OH)F electrode showed an excellent specific capacity of 756 mAh g(-1). The Co0.6Zn0.4(OH)F electrode also exhibited an excellent capacitance contribution rate, indicating good rate performance. In addition, the hydroxyl and oxygen vacancies in the electrode material promoted the lithium/dilithium reactions. Therefore, Co0.6Zn0.4(OH)F is an excellent lithium storage material with high rate; thus, it has a certain potential application value in the future. |
