Abstract
A capacitor cell element includes a dielectric, which has a first metal coating on a first side and has a second metal coating on a second side. The first metal coating on the first side leaves free a first edge region, and the second metal coating on the second side leaves free a second edge region. The first edge region and the second edge region are disposed at opposite ends of the dielectric. A capacitor including the capacitor cell element is also provided. The capacitor cell element and the capacitor have a high volumetric energy density and at the same time are self-healing.
