Non-aqueous electrolyte secondary battery |
| abstract |
(57) [Summary] (Modified) [PROBLEMS] To provide a nonaqueous electrolyte secondary battery with improved initial charge / discharge efficiency and charge / discharge cycle characteristics at low cost. SOLUTION: In a nonaqueous electrolyte secondary battery using a negative electrode active material capable of inserting and extracting lithium ions, the Rp value (average line height) of the active material layer surface of the active material constituting the negative electrode, preferably a carbonaceous material ) Is 25 μm or less, and the surface roughness is kept low, which is one of the causes of deterioration of charge / discharge cycle deterioration. The nonaqueous electrolyte secondary battery has a low amount of film formed on the surface of the negative electrode active material. . |
