Abstract
Disclosed is anode for use in a lithium ion secondary battery. The anode includes an anode current collector and an anode active material arranged thereon, in which the anode active material contains amorphous carbon and at least one metal dispersed in the amorphous carbon, and the at least one metal is selected from: 30 to 70 atomic percent of Si; and 1 to 40 atomic percent of Sn. The anode gives a lithium ion secondary battery that has a high charge/discharge capacity and is resistant to deterioration of its anode active material even after repetitive charge/discharge cycles.
