Ceramic capacitors are an indispensable component in electronic circuits, since they are used in various applications such as timing, filtering, and decoupling. These capacitors are doped with REEs that improve their operating life and electrical properties.
Recently, we have developed one novel kind of rare earth and transitional metal colloidal supercapacitors, which can deliver higher specific capacitance than electrical double-layer capacitors (EDLC) and traditional pseudocapacitors.
All these capacitors are doped with REEs of intermediate ionic radii (such as Dy, Ho, and Er), since they improve the operating life (reliability) and electrical properties of the ceramic capacitors. The improvements in electric properties are a lower dissipation factor, lower aging rate, and a stable capacitance over a wide temperature range.
