Aluminum Electrolytic Capacitors
As is the case with all capacitors, an aluminum electrolytic capacitor comprises two electrically con-ductive material layers that are separated by a dielectric layer. One electrode (the anode) is formed by an aluminum foil with an enlarged surface area. The oxide layer (Al2O3) that is built up on this is used as the dielectric.

Controlled Self-Healing of Power Film Capacitors
To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates. A micrograph is shown in Figure 5, where an elementary capacitive cell has experienced a defect, and the resulting overcurrent condition has broken all four of its fuses ...
