The present invention is to provide a multifunctional heat-radiant plate capable of effectively emitting the heat accumulated in a battery cell and a module and having additional functions such as a sensor function, a vibration control function, a battery stability control function, and an energy harvest function. To this end, the present invention comprises: a thermally conductive plate as an interface component for heat radiation, wherein the thermally conductive plate is interposed between battery cells; composite sheets laminated on both surfaces of the thermally conductive plate; electrically conductive metal layers laminated on the composite sheets; and electrodes respectively connected to the thermally conductive plate and the metal layer. The composite sheet is formed by dispersing a piezoelectric material and a thermally conductive filler in a matrix resin, thereby filling the matrix resin with the piezoelectric material and the thermally conductive filler. |
