The issue of the present invention is to provide a battery in which capacity degradation of the battery has been suppressed with respect to a high-current charge/discharge cycle. The non-aqueous electrolyte rechargeable battery of the present invention is a non-aqueous electrolyte rechargeable battery having a positive electrode, a negative electrode, and a non-aqueous electrolyte. In this non-aqueous electrolyte rechargeable battery, the negative electrode has a negative electrode compound layer containing as negative-electrode active materials scaly graphite particles, and polyhedral graphite particles whose surface has been coated with amorphous carbon. Of the total amount of active materials contained in the negative electrode compound layer, the scaly graphite particles are preferably from 60 parts by mass or more to 90 parts by mass or less, the polyhedral graphite particles are preferably from 10 parts by mass or more to 40 parts by mass or less, and the surface of the scaly graphite particles is preferably coated with amorphous carbon. Also, the binder component in the negative electrode compound layer is preferably from 2.05 parts by mass or more to 2.35 parts by mass or less of the total compound layer. |
