Abstract
An electrochemical device includes a cathode, an anode, a separator and a binding layer. The separator is disposed between the cathode and the anode, and at least one binding layer is included between the cathode and the anode. The binding layer includes a high molecular polymer. A dielectric constant of the high molecular polymer is 5 F/m to 50 F/m. By optimizing the dielectric constant of the high molecular polymer in the binding layer of the electrochemical device, a binding force of the binding layer can be effectively increased, deformation of the anode or the cathode due to volume swelling during charge and discharge cycles is reduced, and peeling from the separator is avoided.
