This invention relates to the field of lithium battery technology, and in particular to a method for preparing a lithium-ion battery cell. The invention discloses a method for preparing a lithium-ion battery cell, comprising: first, preparing a positive electrode slurry containing modified titanium aluminum carbide, graphene oxide, etc., and a negative electrode slurry containing aminated carbon nanotubes, zinc aluminum spinel, etc., both processed according to specific proportions and processes; second, coating the positive and negative electrode slurries separately onto a current collector, and obtaining positive and negative electrode sheets through drying, coating with a coating agent, etc.; next, preparing a composite separator coated with a separator coating agent and curing it; finally, winding the separator in a positive-separator-negative-separator sequence, and obtaining a lithium-ion battery cell through drying, encapsulation, electrolyte injection, formation, etc.

The present application relates to the technical field of electrode material, and particularly relates to a preparation method of seamless integrated zinc negative electrode material.In the present application, a three-dimensional porous structure vertical graphene is constructed on the surface of a substrate, and the surface of the vertical graphene is functionally treated to serve as a zinc plating framework, so that zinc is uniformly loaded on the surface of the substrate, and then a MOF protective layer is coated on the surface of the vertical graphene, thereby obtaining the seamless integrated zinc negative electrode material.In the present application, the surface functional treatment introduces hydrophilic functional groups to the surface of the vertical graphene to enhance the interaction and uniform electric field distribution;the introduction of the MOF protective layer does not destroy the surface morphology, and the thin and uniform MOF protective layer can also exclude large-size charged ion complexes.
