摘要：
A negative electrode for a lithium-ion secondary cell, the negative electrode including a layered body of a collector and a negative electrode active material layer containing an alloy-based material (A) containing silicon or tin as a constituent element, a carbon coating (C) that covers the surface of the alloy-based material (A), carbon particles (B), and a binder (D), wherein the negative electrode for a lithium-ion secondary cell is characterized in that the total pore volume and average pore diameter of the carbon particles (B), as measured by nitrogen gas adsorption, satisfy the ranges of 1.0×10 -2 to 1.0×10 -1 cm 3 /g and 20 to 50 nm, respectively. The negative electrode for a lithium-ion secondary cell, and a lithium-ion secondary cell in which such a negative electrode for a lithium-ion secondary cell is used, have a high capacity and excellent cycle characteristics.
