Japanese Patent JP6040997

B2

[TECHNICAL PROBLEM] To provide a negative electrode for an electric device, such as a Li ion secondary battery, exhibiting good balanced characteristics of providing initial capacity and maintaining high cycle characteristics. [SOLUTION TO PROBLEM] The negative electrode for an electric device includes: a current collector; and an electrode layer containing a negative electrode active material, an electrically-conductive auxiliary agent and a binder and formed on a surface of the current collector. The negative electrode active material is a mixture of a carbon material and an alloy represented by the following formula (1): Si x Sn y M z A a ...(1) (in formula (1), M is at least one metal selected from the group consisting of Al, V, C, and combinations thereof, A is inevitable impurity, x, y, z, and a represent mass percent values and satisfy 0 < x < 100, 0 < y < 100, 0 < z < 100, and 0 ‰¤ a < 0.5, x + y + z + a =100).
