    摘要： This invention relates to electroless autocatalytic plating of platinum onto a substrate, an aqueous platinum plating bath, a process for plating a uniform coating of platinum onto various substrates using an electroless autocatalytic plating composition, and a platinum plated article formed therefrom. The plating bath of this invention allows direct autocatalytic plating of platinum on catalytically active and inactive, conductive and non-conductive substrates, avoiding the extra costs of activating a catalytically inactive substrate.

    摘要： In accordance with the invention, there is a battery defect detection method comprising applying a current ramp to a battery; determining a first time (t1) when a current of the battery reaches a maximum current (Ipeak), and determining a second time (t2) when a terminal voltage of the battery reaches a maximum voltage (Vpeak). The method also includes determining a differential (d), wherein (d)=/(t1)−(t2)/, and wherein (d) corresponds to a magnitude of defects in the battery.

    摘要： In accordance with various embodiments, there is a method for determining the specific gravity of a battery. Various embodiments include the steps of applying an increasing current ramp to a battery and measuring a response voltage of the battery when the increasing current ramp is applied to the battery. When the current ramp reaches a predetermined current a decreasing current is supplied to the battery and the battery's voltage response is measured. The specific gravity of the battery can be determined based on the voltage response of the battery to the applied current ramp.

    摘要： This invention relates to electroless plating of silver onto a substrate, an aqueous silver plating bath, a process for plating a uniform coating of silver onto various substrates using an electroless plating composition, and a silver plated article formed therefrom. The plating bath neither contains nor generates toxic or flammable substances or substances that may contaminate the silver coating. By avoiding strong complexing agents, virtually pure silver may be precipitated from the bath by simple boiling. Silver electroless autocatalytic plating bath consists of silver nitrate, ammonium hydroxide and hydrazine hydrate.
