    摘要： An oxygen plasma process for treating a dielectric oxide layer, particularly an anodic oxide, subsequent to its incorporation into an electrolytic capacitor is described. The present treatment reduces DC leakage and improves shelf life stability of the resulting capacitor in comparison to anodic oxides treated in a conventional manner. This is important for critical applications such as implantable cardioverter defibrillators where capacitor charging time and charge/discharge energy efficiency are critical.

    摘要： An electrical energy storage device such as a wet tantalum electrolytic capacitor or an electrochemical cell such as a lithium/silver vanadium oxide cell is described. The enclosure comprises a drawn casing portion having a planar face wall supporting a surrounding sidewall and is shaped to nest the anode, cathode and intermediate separator components. A mating cover is a stamped planar piece of similar material having a periphery edge welded to the edge of the casing portion surrounding sidewall. In order to prevent heat generated during the welding process from damaging the separator, the anode portion adjacent to the weld site is contoured. This provides sufficient space between the weld and the separator supported on the anode at the contour so that what heat is transmitted to the separator by convection and conduction mechanism will not damage the separator.

    摘要： An anode for an electrolytic capacitor is described. The anode is of a valve metal in powdered form, for example tantalum powder, that has been pressed into a pellet and sintered under a vacuum at high temperatures. Preferably, a poly(alkylene) carbonate binder is used to promote cohesion with the pressed powder body. The binder adds green strength to the pressed body and helps with powder flow before pressing. The poly(alkylene) carbonate binders are superior in that they leave virtually no residual carbon behind when burnt out during the sintering process. The pressed valve metal powder structure is then anodized to a desired voltage in a formation electrolyte to form a continuous dielectric oxide film on the sintered body as well as a terminal lead/anode lead weld extending therefrom.

    摘要翻译： 对电解电容器的阳极进行说明。 阳极是粉末形式的阀金属，例如钽粉末，其被压制成颗粒并在高温下在真空下烧结。 优选地，使用聚（亚烷基）碳酸酯粘合剂来促进与压制粉体的内聚力。 粘合剂对压制体增加了生坯强度，并在压制之前帮助粉末流动。 聚（亚烷基）碳酸酯粘合剂的优点在于，在烧结过程中烧成时实质上不留下残留的碳。 然后将压制阀金属粉末结构在地层电解质中阳极氧化至所需电压，以在烧结体上形成连续的电介质氧化膜，以及从其延伸的端子引线/阳极引线焊接。

    摘要： An electrolytic capacitor comprising a plurality of polymeric structures molded about the periphery of the anode pellet is described. The polymeric structures contact between a weld strap surrounding the butt seam between mating “clamshell” casing portions and the anode pellet sidewall. That way, the anode pellet is restrained from moving along both an x- and y-axes inside the casing. Having the cathode active material contacting the opposed major casing sidewalls being in a closely spaced relationship with the anode pellet through an intermediate separator prevents movement along the z-axis. The resulting capacitor is particularly well suited for use in high shock and vibration conditions.

    摘要： A method for improving the electrical conductivity of a substrate of metal, metal alloy or metal oxide comprising directing a high energy beam of doping ions from Group VIII onto a substrate. This causes an intermixing of the doping ions with the native oxide of the substrate metal or metal alloy. The native oxide layer is changed from being electrically insulating to electrically conductive. The high-energy beam is an ion beam from a high-energy ion source. The thusly-treated substrate is useable in the manufacture of electrodes for devices such as capacitors and batteries.
