摘要： A solid electrolytic capacitor that comprises a capacitor element, a lead wire, an anode termination, and a cathode termination is provided. The capacitor element contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. Further, the lead wire is in electrical contact with the anode body and contains a first region that is located in proximity to a surface of the capacitor element. The lead wire contains a core that extends outwardly from the surface, and an oxide layer coats at least a portion of the core within the first region.

摘要： A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.

摘要： A wet electrolytic capacitor that contains a casing that contains a cylindrical sidewall is provided. The cylindrical sidewall defines an inner surface that surrounds an interior. First and second outer anodes are positioned within the interior of the casing. The first outer anode has a radiused sidewall and an opposing planar sidewall and the second outer anode has a radiused sidewall and an opposing planar sidewall. A central anode is also positioned within the interior of the casing between the first and second outer anodes. The central anode contains opposing first and second outer sidewalls intersecting with opposing first and second inner sidewalls. The first and second inner sidewalls are planar, and the first planar inner sidewall of the central anode faces the planar sidewall of the first outer anode and the second planar inner sidewall of the central anode faces the planar sidewall of the second outer anode.

摘要： To improve the reliability of a power storage device. A granular active material including carbon is used, and a net-like structure is formed on part of a surface of the granular active material. In the net-like structure, a carbon atom included in the granular active material is bonded to a silicon atom or a metal atom through an oxygen atom. Formation of the net-like structure suppresses reductive decomposition of an electrolyte solution, leading to a reduction in irreversible capacity. A power storage device using the above active material has high cycle performance and high reliability.
