Method for producing negative electrode active material for lithium ion secondary battery
A method for producing a negative electrode active material for a lithium ion secondary battery, comprising a step of charging either silicon and copper (II) oxide or silicon and copper metal in a pulverization device, pulverizing either the silicon and copper (II) oxide or silicon and copper metal, and simultaneously mixing either silicon and copper (II) oxide or silicon and copper metal thus pulverized. A negative electrode active material for a lithium ion secondary battery is produced by the method.
