Aluminum foil coating composition for lithium ion battery current collector and carbon-coated aluminum foil

The invention belongs to the technical field of preparation of lithium ion battery current collectors, and particularly relates to an aluminum foil coating composition for a lithium ion battery current collector and a carbon-coated aluminum foil, starting from aluminum foil coating slurry, a water-insoluble pore-forming agent is added to enable a coating to generate uniform micropores in a drying stage, and the honeycomb porous carbon-coated aluminum foil is obtained. The method is simple and easy to operate, can increase the surface roughness of the carbon-coated aluminum foil to improve the peel strength between the carbon-coated aluminum foil and the positive electrode material, and can reduce the resistivity of the carbon-coated aluminum foil and increase the contact area between the positive electrode material and the current collector, thereby reducing the internal resistance of the battery and improving the performance of the battery. 本发明属于锂离子电池集流体的制备技术领域，具体涉及一种锂离子电池集流体用铝箔涂布组合物、涂碳铝箔，从铝箔涂布浆料着手，加入不溶于水的成孔
