当对普通电容器的两块极板施加外部电压时，普通电容器的电荷存储原理与双电

When external voltage is applied to the two plates of the conventional capacitor, the same principle of charge storage charge storage capacitor and the general principles of an electric double layer capacitor, i.e., positive charges corresponding to the positive electrode, a negative electrode corresponding negative charge. During charging, the positive and negative electrodes, respectively, positive and negative charges accumulated in the electric field, the electrolyte anions move to the positive electrode, the negative electrode move to the cation, thereby forming an electric double layer capacitor orientation. In the discharge process, electrons emitted from the external circuit with the accumulation of ions at the electrode and electrolyte interface will be re-released back into solution

当对普通电容器的两块极板施加外部电压时，普通电容器的电荷存储原理与双电层电容器的电荷存储原理相同，即正电极对应正电荷、负电极对应负电荷。在充电的过程中，正极和负极分别积聚正电荷和负电荷，在电场的作用下，电解液中阴离子移动到正极，阳离子移动到负极，从而形成定向双电层电容。在放电过程中，随着电子从外电路放出，电极与电解液界面处积聚的离子将重新释放回到溶液中

When external voltage is applied to the two plates of the common capacitor, the charge storage principle of the common capacitor is the same as that of the double-layer capacitor, that is, the positive electrode corresponds to the positive charge and the negative electrode corresponds to the negative charge. In the process of charging, the positive and negative charges are accumulated in the positive and negative electrodes respectively. Under the action of electric field, the anions in the electrolyte move to the positive electrode and the cations move to the negative electrode, thus forming a directional double-layer capacitor. During the discharge process, as the electrons are released from the external circuit, the ions accumulated at the interface between the electrode and the electrolyte will be released back to the solution
