Description

technical field [0001] The invention belongs to the technical field of preparation of solid electrolytic capacitors, and in particular relates to an improved impregnation method for high-voltage wound solid electrolytic capacitors. Background technique [0002] The biggest difference between winding solid aluminum electrolytic capacitors (hereinafter referred to as solid capacitors) and traditional liquid aluminum electrolytic capacitors is the use of different catholytes. The catholyte of liquid aluminum capacitors is electrolyte, while the catholyte of solid capacitors is conductive. Polymer Materials. [0003] The conductivity of conductive polymer materials is usually 2 to 3 orders of magnitude higher than that of electrolytes, and the conductivity is less affected by temperature and has good thermal stability. Solid capacitors made of conductive polymer materials fundamentally have the characteristics of long life, safe use, extremely low ESR, high rated ripple current...
