NOVELTY - The method involves separating (D) positive electrode into positive electrode electrical power collector and positive electrode active material through a process in which impact force providing unevenness is given. A negative electrode is separated into anode collector and negative electrode active material. A metal element containing positive electrode electrical power collector and anode collector in plus sieve side, and the positive electrode active material and negative electrode active materials is collected (E) to sieving side.    USE - Method for collecting valuable metal such as cobalt (claimed), lithium, nickel, manganese, titanium, vanadium, iron, and copper, and alloy containing aluminum, copper, nickel, silver, gold, chromium, iron, tin, lead, tungsten, molybdenum and zinc from noncommercial lithium ion battery incorporated in electronic device such as notebook personal computer, video camera, digital camera, tablet-type terminal, and mobile telephone, and vehicle.    ADVANTAGE - The valuable metals are collected from the used lithium ion battery at high separation-and-recovery efficiency. The high separation-and-recovery efficiency of positive electrode active material and electrical power collector is achieved at low cost. The process operation and safety control when separate-and-recovering valuables from lithium ion battery are made easy.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the process for collecting valuables from lithium ion battery.
