1 Capacitor aluminum crystals—definition of orientation and texture The semi-continuous casting slab, hot-rolled plate, cold-rolled plate or final aluminum foil (Figure 1.7) involved in aluminum electrolytic capacitors are all composed of aluminum crystals. Usually, the normal direction of the aluminum plate or aluminum foil is represented by ND, the rolling direction is represented by RD, and [...]

Electrolyte of aluminum electrolytic capacitor—the working electrolyte of capacitor is another key factor in addition to corrosion and empowerment. It is related to the operating temperature range of aluminum electrolytic capacitors, as well as working indicators such as life and reliability. There are generally two types of working electrolytes: liquid electrolytes and solid electrolytes. 1 Electrolyte [...]

At present, although liquid electrolytes are widely used, solid electrolytes have gradually attracted widespread attention. If solid electrolytes completely replace liquid electrolytes, all-solid-state ionic devices can be obtained, which will also be a major change in the field of electrochemical device energy storage. . Generally speaking, the room temperature conductivity of a solid electrolyte with practical [...]
