Self- healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary. In the production of the dielectric film, contamination can occur or a process control problem can result in compromised dielectric strength.
The intense heat generated by this arc causes the metallization in the vicinity of the arc to vaporise (figure 2). Simultaneously it re-insulates the electrodes and maintains the operation and integrity of the capacitor (figure 3).
Abstract: Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions. These SH events have the potential to inflict damage on both the polypropylene (PP) film and the electrode layer.
Self-healing materials can be used with electrodes or electrolytes in a supercapacitor device. Self-healing supercapacitors are evolving quickly but are still in their infancy due to high cost, limited performance, and complex fabrication processes. This article presented the different self-healing material and their application in supercapacitors.
Self-healing materials increase the lifetime of the supercapacitor device. The supercapacitor has a long cycle life and a quick charge–discharge rate, contributing to its high power density [ 54, 55, 56 ]. But a minor crack can reduce the supercapacitor performance, which is unsafe.
