摘要:
A double-layer capacitor is composed of at least two individual double-layer capacitor cells connected in series, with bipolar electrodes and electrolyte layers being provided alternately. Each a bipolar electrode includes an electrically conducting carrier with an active layer applied on both sides, the active layer having a low resistance and large active surface. The carrier provides an electrically conducting barrier between the adjoining ion-conducting electrolyte layers, and the electrodes and electrolyte layers are permanently connected. An electrically conducting binder is integrated into the active layer, or a separate connecting layer is provided to promote adhesion between the active and electrolyte layers.
