The present invention discloses a physical separation and enrichment method for resource components of discarded lithium-ion batteries; This method achieves separation and enrichment between the shell, separator, electrolyte, negative electrode material, positive electrode material, positive electrode current collector, and negative electrode current collector of lithium-ion batteries through a series of combined processes such as discharge, shear crushing, low-temperature drying, magnetic separation, air separation, ultrasonic hydraulic screening, alternating cold and hot drying, hammer crushing, particle size screening, and eddy current sorting. The present invention can completely separate and enrich the resource components in waste lithium-ion batteries to obtain high-purity products. The entire separation and enrichment process is pollution-free, free from chemical reactions, and free from secondary pollutants. The process flow is simple, the equipment used is highly standardized, and the separation and enrichment effect is good. It is suitable for use by waste lithium-ion battery recycling enterprises.
