Abstract:
Provided is a negative electrode plate. A negative electrode plate includes a negative current collector and a first coating layer arranged on a surface of the negative current collector. The negative electrode plate further includes a second coating layer arranged on a surface of the first coating layer. The first coating layer contains a negative electrode active material. The second coating layer contains a heat-resistant insulating material. The heat-resistant insulating material is selected from an oxide or a hydroxide containing at least one of elements selected from a group consisting of Mg, Si, Zr and Y. In the present application, the second coating layer containing the heat-resistant insulating material is coated on a surface of the conventional negative electrode active material layer, so an instantaneous high power discharge in a short circuit of the secondary battery can be avoided, and a safety performance of the battery can be improved.

Claim (Index 7):
The negative electrode plate according to  claim 1 , wherein the second coating layer further comprises a binder and a thickener, wherein a mass ratio of the heat-resistant insulating material, the binder and the thickener is (95-97): (2-3): (1-2).
