SEPARATING AND RECOVERING METHOD OF CURRENT COLLECTOR AND POSITIVE ELECTRODE ACTIVE MATERIAL FROM POSITIVE ELECTRODE MATERIAL FOR LITHIUM ION BATTERY

摘要

PURPOSE: A separating and collecting method of a current collector and a positive active material is provided to obtain the current collector and the positive active material with high efficiency and low costs. CONSTITUTION: A separating and collecting method of a current collector and a positive active material comprises a step of preparing a positive electrode material that the current collector and the positive active material are attached to each other by a binder; a step of cutting the positive electrode material; a step of collecting the positive electrode material into the lower part of a sieve by sorting the positive electrode material with a sieve; a step of applying impact strength to the positive electrode material, to separate the positive active material from the current collector; and a step of sorting the positive electrode material by the sieve and collecting the positive active material inside the lower part of the sieve and the current collector inside of the upper part of the sieve.
