Title: Current collector, electrode sheet thereof and battery
Inventor: LIANG CHENGDU
IPC: H01M4/66
Filed: 2018-08-16
Abstract: To provide a technology relating to the field of batteries, and, particularly, relating to a current collector, an electrode sheet thereof, and a battery.SOLUTION: A current collector includes an insulation layer and a conductive layer. The insulating layer mounts the conductive layer thereon, and the conductive layer mounts an electrode active material layer thereon. The conductive layer is located above at least one surface of the insulation layer, and, when D2 represents the thickness of the conductive layer, D2 satisfies a conditional expression of 300 nm≤D2≤2 μm. The current collector further includes a protective layer provided on at least one surface of the conductive layer. The current collector can increase the short circuit resistance of a battery when a short circuit occurs under abnormal conditions, such that a short circuit current can be greatly reduced, and thus heat generated by the short circuit can be greatly reduced, thereby improving battery safety. In addition, the protective layer can improve the mechanical strength of the conductive layer, further improve battery safety, and at the same time prevent the conductive layer from being damaged, oxidized or corroded, etc., and thus significantly improve an operating stability and a service life of the current collector.SELECTED DRAWING: Figure 2
