Abstract:
The present application relates to an anode electrode and an electrochemical device containing the same. The anode electrode comprises: a current collector, including a first surface and a second surface opposite to the first surface; an insulation layer being disposed on a peripheral portion of the first surface and/or a peripheral portion of the second surface; and a protection layer being disposed on the insulation layer and covering the first surface and/or the second surface. According to an embodiment of the present application, the insulation layer and the protection layer are disposed in the anode electrode of the electrochemical device to construct a seal cavity, which defines a space of the deposition of lithium metal on the anode electrode, thereby resolving the safety problem caused by the irregular deposition of the lithium metal.
