    Abstract: An anodized pressed valve metal powder pellet is described. The anodized pellet is particularly useful as an anode in an electrolytic capacitor having an improved breakdown voltage. The anodized pellet is formed by periodically holding the pellet at a constant voltage and allowing the current to decay over a period of time, or by turning the formation power supply off altogether during the anodization process. Either way provides an opportunity for heated electrolyte to diffuse from the anodized pellet.

    Abstract: A protection device and a method of protecting an electrical component. The protection device has a protective housing and a terminal cap. The protective housing has a base with a contact hole therethrough for receiving an electrical terminal pin, and has a projecting shoulder extending from the base to a first distance from the base. The protective housing also has a retaining clip extending from the base to a second distance from the base, the second distance being greater than the first distance. The terminal cap has a first side and a second side, and in use, at least part of the first side of the terminal cap contacts the projecting shoulder and at least part of the second side of the terminal cap contacts the retaining clip. A method according to the present invention includes steps for determining the temperature to which the protective housing was exposed.

    Abstract: A new sandwich cathode design is provided having a first cathode structure of a first cathode active material of a relatively low energy density but of a relatively high rate capability, for example SVO, mixed with a second cathode active material having a relatively high energy density but a relatively low rate capability, for example CF x , with the percentage of SVO being less than that of CF x and sandwiched between two current collectors. Then, a second cathode mixture of SVO and CF x active materials is contacted to the outside of the current collectors. However, the percentage of SVO to CF x is greater in the second structure than in the first. Such an exemplary cathode design might look like:
       (100-y)% SVO + y% CF x , wherein 0 ≤ y ≤ 100/current collector/(100-x)% SVO + x% CF x , wherein 0 ≤ x ≤ 100/current collector/(100-y)% SVO + y% CF x , wherein 0 ≤ y ≤ 100, and wherein the ratio of x to y is selected from the group consisting of y
