| titleOfInvention | Current collector and lithium ion battery containing same |
| abstract | The invention discloses a current collector and a lithium ion battery containing the current collector, wherein the current collector comprises a conductive layer, an insulating layer and an enhancement layer; the number of the conducting layers is two, an insulating layer is arranged between the two conducting layers, and an enhancement layer for enhancing the conductivity is also arranged between the conducting layers and the insulating layer; the conducting layer, the reinforcing layer and the insulating layer are compounded by adopting vacuum plating or electrolytic plating; the conducting layer is made of metal materials, and the thickness of the conducting layer is 0.1-1 mu m; the insulating layer is made of an organic polymer insulating material and has a thickness of 2-8 mu m; the enhancement layer is made of at least one of carbon-based conductive materials and nano conductive ceramic materials, and the thickness of the enhancement layer is 0.1-1 mu m. According to the invention, the insulating layer is arranged between the two conducting layers, and the reinforcing layer is arranged between the conducting layers and the insulating layer, so that the weight of the current collector is reduced, the conductivity of the current collector is ensured, the toughness of the current collector can be improved, and the consistency and the safety of a product are improved. |
