NOVELTY - The method involves separating positive electrode material into electrical power collector and positive electrode active material through process in which impact force which provides unevenness is given to positive electrode material, and collecting ground materials of positive electrode material. The positive electrode material is separated into electrical power collector and positive electrode active material by dielectric constant's making collected ground material to contact with aprotic polar solvent, and dissolving binder component.    USE - Method for separate-and-recovering electrical power collector such as alloy containing aluminum, copper, nickel, silver, gold, chromium, iron, tin, lead, tungsten, molybdenum and zinc, and positive electrode active material such as lithium, cobalt, nickel, manganese, titanium, vanadium and iron, and copper from lithium ion battery positive electrode material incorporated in electronic device such as notebook personal computer, video camera, digital camera and mobile telephone, and electric vehicle.    ADVANTAGE - The electrical power collector and positive electrode active material are efficiently separate-and-recovered from the lithium ion battery positive electrode material at a high separation-and-recovery efficiency. The high separation-and-recovery efficiency is obtained at low cost.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the process for separate-and-recovering electrical power collector and positive electrode active material from lithium ion battery positive electrode material.
