Abstract
A solid electrolytic capacitor that comprises an anode, a dielectric layer overlying the anode; and a cathode that contains a solid electrolyte layer overlying the dielectric layer. The anode comprises a porous, sintered body that defines a surface. The body is treated so that the surface contains a non-metallic element having a ground state electron configuration that includes five or more valence electrons at an energy level of three or more (e.g., phosphorous).
