| titleOfInvention | Secondary battery |
| abstract | The present invention provides a secondary battery, which includes a positive electrode piece, a negative electrode piece, an electrolyte and a separator, the positive electrode piece includes a positive electrode current collector and a positive electrode current collector disposed on at least one surface of the positive electrode current collector and including a positive electrode active material A positive electrode sheet includes a negative electrode current collector and a negative electrode diaphragm provided on at least one surface of the negative electrode current collector and including a negative electrode active material. The secondary battery also satisfies: 0.1≦(D50 negative electrode ×M negative electrode )/[(D50 positive electrode +4)×(M positive electrode +4)]≦1.5. The present invention obtains a secondary battery having both long cycle life, high energy density and rapid charge-discharge capability by reasonably matching the relationship between the particle size of the positive and negative active materials and the capacitance of the positive and negative film sheets. |
