A negative pole piece, secondary battery and electric vehicle |
| abstract |
The present invention provides a negative pole piece, a secondary battery and an electric vehicle. The negative electrode pole piece includes a negative electrode current collector and a multi-layer active material layer formed on the negative electrode current collector; the multi-layer active material layer includes at least a first active material layer and a second active material layer; the first active material layer contains the first negative electrode active material layer. The second active material layer contains the second negative electrode active material; the ratio of the thickness of the first active material layer to the average particle size of the first negative electrode active material is 2.0-4.0. The ratio of the thickness of the second active material layer to the average particle size of the second negative electrode active material is 2.2 to 5.0. The battery using the negative electrode plate of the present invention can have good cycle life and fast charging performance at the same time. |
