This application specifically discloses a pre-lithiated current collector, its preparation method and application, and deposition equipment. The pre-lithiated current collector includes a polymer layer and a metal layer and a lithium replenishment layer sequentially disposed on at least one surface of the polymer layer. The lithium replenishment layer includes a binder layer, a gradient lithium layer, a pure lithium layer, and a protective layer. The lithium content in the gradient lithium layer near the binder layer is less than the lithium content in the region near the pure lithium layer. The protective layer includes an inorganic underlayer disposed on the surface of the pure lithium layer and an inorganic / polymer composite top layer disposed on the side of the inorganic underlayer away from the pure lithium layer. The pre-lithiated current collector of this application exhibits excellent adhesion between interfaces, precise lithium replenishment, and excellent cycle performance.
