1. An electrode plate for use in cardiac defibrillation, the electrode plate comprising:
a hermetic shell having an inflation port and an overflow aperture, the overflow aperture provided in an exposed surface of the hermetic shell, wherein the exposed surface has electrical conductivity;
a capsule disposed in the hermetic shell, the capsule defining a cavity for storage of a conductive paste therein, the cavity defining an inlet orifice and an outlet orifice, the overflow aperture disposed at the outlet orifice, the cavity isolated from a hollow internal space of the hermetic shell; and
a sealing structure comprising a sealing component and a force applying component, the sealing component disposed at the overflow aperture, the sealing component configured to close the overflow aperture and the outlet orifice when the hermetic shell is not inflated, the force applying component disposed on the hermetic shell and connected to the sealing component after being inserted into the capsule through the inlet orifice, the force applying component configured to pull the sealing component when the hermetic shell is inflated and expanded, so that the overflow aperture and the outlet orifice are opened and communicated with each other.
