Lithium-ion secondary battery |
| abstract |
The technical problem solved by the invention is to obtain a lithium-ion secondary battery with excellent high-rate discharge characteristics. The means to solve the technical problem is: by using Li a (Ni x Co y Al 1-x-y )O 2 (0.95≤a≤1.05; 0.5≤x≤0.9; 0.05≤y≤0.2; 0.7≤ x+y≤1.0) is used as the positive electrode active material, and the electrode density of the positive electrode is 3.75-4.1g/cm 3 , and the positive electrode is a lithium-ion secondary battery with a BET specific surface area of 1.3-3.5m 2 /g as the electrode, so that Excellent high rate discharge characteristics are obtained. |
