Winding cells, lithium ion secondary batteries and negative electrode pieces |
| abstract |
The invention discloses a winding type battery cell, a lithium ion secondary battery and a negative electrode pole piece. The negative electrode pole piece of the winding type battery core comprises a negative electrode current collector and a negative electrode active electrode arranged on two opposite surfaces of the negative electrode current collector. The material layer, the negative electrode active material layer includes a negative electrode active material; wherein, the two negative electrode active material layers respectively include lone pair region active material layers and opposite region active material layers distributed successively in the length direction of the negative electrode pole piece, and the two lone pair region active material layers respectively. The active material layers in the pair area are arranged at both ends of the negative pole piece in the length direction, and a first metal lithium layer is arranged on the surface of one or both of the active material layers in the two lone pair areas, so that the two lone pair area active material layers are provided with a first metal lithium layer. One or both of the region active material layers form a first pre-lithium intercalation compound. The wound battery core provided by the invention enables the lithium ion secondary battery to take into account high cycle performance and storage performance at the same time. |
