| titleOfInvention | Coated aluminum cathode, preparation method and application thereof, lithium secondary battery and application thereof |
| abstract | The invention provides a coated aluminum cathode, a preparation method and application thereof, a lithium secondary battery and application thereof, and belongs to the technical field of electrochemical energy storage. The invention provides a coated aluminum cathode, which comprises an aluminum cathode substrate, wherein a copper-nickel alloy coating is arranged on the surface of the aluminum cathode substrate; wherein the copper content in the copper-nickel alloy plating layer is 0.5 wt% -10 wt%. The copper-nickel alloy plating layer containing specific copper and nickel dosage is not easy to alloy with lithium in the charging and discharging process, has no or little volume expansion in the lithium alloying and dealloying process, can effectively inhibit the volume expansion and the pulverization collapse in the circulation process of the aluminum negative electrode matrix, can well maintain the surface structure of the aluminum negative electrode matrix, and ensures the stability of the internal aluminum negative electrode matrix structure. The copper-nickel alloy coating can effectively prevent the electrolyte from reacting with the aluminum cathode matrix, improve the coulombic efficiency and reduce the irreversible capacity. |
