摘要： This invention describes packaging structures and methods for electronic devices, especially for solid electrolytic capacitor devices. A packaging structure applies at least two protective substrates to sandwich one or multiple capacitor elements stacked together in between with an insulating material surrounding the capacitor elements also in between the protective substrates. Each protective substrate comprises an anodic conductor pad and a cathodic conductor pad. The anodic conductor pad is electrically connected to an external anode terminal, which is in turn electrically connected to the tip face of the anode end of the capacitor element. The cathodic pad is electrically connected to the cathode of the capacitor element as well as to an external cathode terminal. For quantity production, the basic concept includes sandwiching hundreds of capacitor elements in between large thin protective substrates and bonding them to the conductor pads on the protective substrates; then filling in the insulating material by a capillary filling process; then curing the assembly into a first intermediate assembly. A second intermediate assembly is then made by cutting slots over the first intermediate assembly to expose the anodic and cathodic ends of each capacitor device for subsequent metal depositions to make the external terminals.

摘要： A capacitor and a method of processing an anode metal foil are presented. The method includes electrochemically etching the metal foil to form a plurality of tunnels. Next, the etched metal foil is disposed within a widening solution to widen the plurality of tunnels. Exposed surfaces of the etched metal foil are then oxidized. The method includes removing a section of the etched metal foil, where the section of the etched metal foil includes exposed metal along an edge. The section of the etched metal foil is placed into a bath comprising water to form a hydration layer over the exposed metal on the section of the etched metal foil. The method also includes assembling the section of the etched metal foil having the hydration layer as an anode within a capacitor.

摘要： A capacitor assembly that is capable of exhibiting good electrical properties even under a variety of conditions is provided. More particularly, the capacitor contains a capacitor element that includes a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. The solid electrolyte contains an adhesion layer that is positioned between an inner conductive polymer layer and an outer conductive polymer layer. The adhesion layer is formed from an organometallic compound and the outer layer is formed from pre-polymerized conductive polymer particles.

摘要： A system that includes an energy device having an active region configured to generate or consume electrical energy provided by an electrical current is discussed. A current limiter is disposed between the energy device and a current collector layer. The current limiter controls the current flow between the energy device and the current collector layer. A plurality of electrochemical transistors (ECTs) are arranged in an array such that each ECT in the array provides localized current control for the energy device. Each ECT includes a gate electrode, a drain electrode, a source electrode, and a channel disposed between the drain and the source electrodes. An electrolyte electrically couples the gate electrode to the channel such that an electrical signal at the gate electrode controls electrical conductivity of the channel. The current collector layer is a shared drain or source electrode for the ECTs.

摘要： A vehicle power system includes loads, a battery coupled to the loads, an ultra-capacitor coupled to the battery, and a bypass circuit. The loads, the ultra-capacitor, and the battery are electrically coupled in series. The bypass circuit monitors the ultra-capacitor and prevents the ultra-capacitor from over-discharging and reversing in polarity.
