This invention belongs to the field of new energy storage materials technology, specifically relating to a method for preparing and applying an ultrathin copper current collector modified with a carbon nanotube composite coating. Addressing the problems of strong lithium repellency, uneven metal deposition, and short cycle life of copper current collectors in electrodeless lithium-ion batteries, this invention constructs a composite functional layer on an ultrathin copper foil, composed of zinc-based oxide rich in oxygen vacancies and carbon nanotubes. In this coating, the zinc-based oxide acts as a highly lithium-affinity site, effectively reducing the metal nucleation overpotential; the carbon nanotube network provides a rapid electron conduction path and alleviates deposition stress. The preparation process is environmentally friendly, employing an aqueous slurry system and a simple heat treatment process. This modified current collector, used in electrodeless lithium-ion batteries, can guide uniform and dense metal deposition, significantly improving the battery's coulombic efficiency and cycle stability.
