As a result, this self-healing supercapacitor features device-level toughness with more than 96% areal capacitance conserved, even under 180° bending (1.6 mm of bending radius). With its high durability and longevity against dynamic deformation and damage, our study demonstrates the high application potential of this supercapacitor …
Learn MoreMetallized 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. However, not all types of SH damage lead to catastrophic failure of the capacitor. Thus, …

Learn MoreA theory of self-healing (SH) in metallized film capacitors (MFCs) is introduced. The interruption of the filamentary breakdown (BD) current in the thin dielectric insulation occurs when the thermally driven increase of the series impedance in the electrode metallization destabilizes the BD plasma arc. The interruption process can be …
Learn MoreThe first mechanically and electrically self-healing supercapacitor has been successfully fabricated. It exhibits excellent self-healing performance with the restoration of the specific capacitance up to 85.7% of its original value even after the 5 th mechanical cutting.
Learn MoreThere are two different mechanisms for self-healing of metalized film capacitors: one is discharge self-healing; the other is electrochemical self-healing. The former occurs at higher voltage, so it is also referred to as high-voltage self-healing; because the latter also occurs at very low voltage, it is often referred to as low-voltage self ...
