| 摘要 |
A non-aqueous electrolyte secondary battery exhibits good high-rate charge/discharge characteristic and good charge/discharge cycle property even when the packing density of the negative electrode is increased. The non-aqueous electrolyte secondary battery includes a positive electrode containing a positive electrode active material, a negative electrode containing a negative electrode active material, and a nonaqueous electrolyte, in which the negative electrode active material is a mixture of a carbon material and metal particles of at least one selected from zinc, aluminum, tin, calcium, and magnesium.
