Encapsulation, for the purpose of this document, is defined as a potting material, e.g., epoxy, silicone, urethane that is applied in a liquid state and subsequently processed (i.e., cured) to form a rigid or rubber-like state. Processing characteristics and curing mechanisms are dependent on the encapsulation chemistries used.

Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage.
Impregnation: Soak the capacitor core with electrolyte to saturate the paper isolation layer and all parts of the corroded aluminum foil to ensure good contact between the oxide layer and the true cathode. This method requires the removal of gas from the core package and vacuum immersion of the electrolyte.
1.3 Scope For the purpose of this document potting can be thought of as the ‘‘liquid material’’ and encapsulation can be interpreted as the application process and cure. Please keep in mind however that the terms potting and encapsulation are commonly interchanged with each other in a variety of electronic protection processes.
Employ a winding machine to neatly wind them together, creating a capacitor core package. Impregnation: Soak the capacitor core with electrolyte to saturate the paper isolation layer and all parts of the corroded aluminum foil to ensure good contact between the oxide layer and the true cathode.
The cathode, on the other hand, consists of a combination of conductive materials, electrolytes (which can be either liquid or solid), and additional materials. The naming of electrolytic capacitors is derived from the electrolyte, which forms the principal component of the cathode.
Electrolytic Capacitor Electrolytic capacitors are capacitors that exist in two forms: non-polar and polar. The anode of these capacitors typically comprises metal foil, such as aluminum or tantalum, with an oxide film, often aluminum oxide or tantalum pentoxide, serving as the dielectric and adhering closely to the anode.
Capacitors possess higher charging/discharging rates and faster response times compared with other energy storage technologies, effectively addressing issues related to discontinuous and uncontrollable renewable energy sources like wind and solar .
