<p>PROBLEM TO BE SOLVED: To provide a method of obtaining a high separating and recovering efficiency of a positive electrode active material and a collector at a low cost.SOLUTION: A method of separating and recovering a collector and a positive electrode active material from a positive electrode material for lithium ion battery includes a step for separating a positive electrode into a collector and a positive electrode active material through a process for pulverizing a positive electrode material for lithium ion battery, having such a configuration that the collector and positive electrode active material are bonded by means of a binder, granularly while giving the wrinkles, and a step for recovering the collector on the sieve upper side and recovering the positive electrode active material on the sieve lower side, by sieving the positive electrode material after pulverization.</p> |
