摘要: An electrolytic capacitor includes an anode body that includes a porous body and a dielectric layer covering the porous body, and a solid electrolyte layer that covers the dielectric layer. The porous body has a first region located near an outer surface of the porous body, and a second region other than the first region. The first region is a region in which a distance from the outer surface of the porous body is shorter than 0.5D, where D is a shortest distance between the outer surface of the porous body and a center of the porous body. A filling proportion R2 of the solid electrolyte layer in the second region is less than a filling proportion R1 of the solid electrolyte layer in the first region. A ratio R2/R1 of the filling proportion R2 to the filling proportion R1 is less than or equal to 1/10.

摘要: An energy storage device can include a cathode and an anode, where at least one of the cathode and the anode are made of a polytetrafluoroethylene (PTFE) composite binder material including PTFE and at least one of polyvinylidene fluoride (PVDF), a PVDF co-polymer, and poly(ethylene oxide) (PEO). The energy storage device can be a lithium ion battery, a lithium ion capacitor, and/or any other lithium based energy storage device. The PTFE composite binder material can have a ratio of about 1:1 of PTFE to a non-PTFE component, such a PVDF, PVDF co-polymer and/or PEO.

摘要: A solid electrolytic capacitor that includes: a capacitor element; a sealing material that seals the capacitor element to form a sealing body; and a vent structure embedded in the sealing material such that a portion of the vent structure is exposed on an outer surface of the sealing body, the vent structure being composed of a material that has a self-sealing valve action in which the vent structure turns into a melt at a reflow mounting temperature and the melt cleaves when receiving pressure of vaporized components generated inside the sealing body so as to form a hole communicating from an inside to the outer surface of the sealing body to discharge the vaporized components, and upon being cooled from the reflow mounting temperature, the melt flows and then solidifies so as to block the hole.
