    摘要： The current invention relates to the preparation of an improved cathode active material for non-aqueous lithium electrochemical cell. In particular, the cathode active material comprises ε-phase silver vanadium oxide prepared by using a γ-phase silver vanadium oxide starting material. The reaction of γ-phase SVO with a silver salt produces the novel ε-phase SVO possessing a lower surface area than ε-phase SVO produced from vanadium oxide (V 2 O 5 ) and a similar silver salt as starting materials. Consequently, the low surface area ε-phase SVO material provides an advantage in greater long term stability in pulse dischargeable cells.

    摘要： 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.

    摘要： 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.

    摘要： A lithium ion electrochemical cell having high charge/discharge capacity, long cycle life and exhibiting a reduced first cycle irreversible capacity, is described. The stated benefits are realized by the addition of at least one phosphate additive having the formula: (R 1 O)P(=O) (OR 2 ) (OR 3 ) and wherein R 1 , R 2 and R 3 are the same or different, wherein at least one, but not all three, of the R groups is hydrogen, or at least one of the R groups has at least 3 carbon atoms and contains an sp or sp 2 hybridized carbon atom bonded to an sp 3 hybridized carbon atom bonded to the oxygen atom bonded to the phosphorous atom.
