摘要： A solid electrolytic capacitor comprising a capacitor element, anode lead extending from a surface of the capacitor element, an anode termination that is in electrical connection with the anode lead, a cathode termination that is in electrical connection with the solid electrolyte, and a casing material that encapsulates the capacitor element and anode lead is provided. A barrier coating is disposed on at least a portion of the capacitor element and is in contact with the casing material. The coating contains a polymeric material that includes a fluorinated component and a non-fluorinated component. The polymeric material has a glass transition temperature of from about 10° C. to about 120° C. and a thermal decomposition temperature of about 200° C. to about 300° C.

摘要： A method for forming a solid electrolytic capacitor that includes an anode containing a valve metal composition, a dielectric overlying the anode, and a solid electrolyte overlying the dielectric is provided. The method comprises forming the dielectric by a process that includes placing the anode into contact with an electrolyte containing an ionic liquid and a valve metal salt and applying a potential difference between the anode and a counter electrode to form a dielectric oxide layer.

摘要： A wet electrolytic capacitor is provided. The capacitor contains an anode comprising an anodically oxidized pellet formed from a pressed and sintered powder, a cathode, and a working electrolyte in communication with the anode and the cathode. The working electrolyte is in the form of a gel and comprises an ammonium salt of an organic acid, inorganic oxide particles, a gelation activator, an acid, and a solvent system that comprises water. The working electrolyte has a pH value of from about 5.0 to about 8.0.
