TLDR
In this article, the authors define the technology issues for next generation energy storage capacitors, starting from the current state-of-the-art for large (over 5 kg) capacitors recently developed for modern pulsed power conditioning applications.Abstract:
Many different types of capacitors are available today, most being designed for mounting on circuit boards or other electronic equipment Generally these fall into the classes of ceramic, tantalum, electrolytic, or DC film capacitors Larger sizes of capacitors are used in applications such as motor drives and kilowatt to multimegawatt average power, power conditioning equipment These larger capacitors, operating to voltages in excess of 25 kilovolts, have traditionally been manufactured with paper or polypropylene films, or some combination therein, with or without a gas-excluding liquid impregnant This paper is focused on defining the technology issues for next generation energy storage capacitors, starting from the current state-of-the art for large (over 5 kg) capacitors recently developed for modern pulsed power conditioning applicationsread more

Linking corrosion and catastrophic failure in low-power metallized polypropylene capacitors
TL;DR: Theoretical analysis indicates that heavy series current at the still-connected end of the metal film and excessive current density in the vestigial links can result in localized heating that exceed the tolerance of the dielectric, resulting in catastrophic failure.

Distributed Circuit Modeling of Multilayer Capacitor Parameters Related to the Metal Film Layer
TL;DR: In this article, the authors compare the performance of two different distributed-circuit topologies, one by design and the other by degradation, and show that the two connection topologies exhibit similar behavior up to at least the typical self resonance frequency of the capacitor, except for the cross-dielectric voltage and cross-width power dissipation profiles which are fundamentally different.
