Metal Accumulation Inhibiting And Performance Enhancing Supplement And A System For Delivering The Supplement

摘要

The invention relates to a metal accumulation inhibiting and performance enhancing isolated or synthesized supplement for use in or in association with rechargeable electrochemical energy storage cells, and a system for delivering the supplement including articles of plastic, articles containing plastic, articles similar to plastic, plastic containers, apparatus, porous electrodes, liquids and electrolytes, in particular, articles, apparatus, electrodes, insolating sheets, liquids and electrolytes associated with rechargeable electrochemical energy storage cells incorporating one or more supplements. An effective amount of the supplement typically exhibits foaming of an electrolyte, providing a visual indicator of activity in attenuating metal deposition on, and thereby reducing metal accumulation on, various surfaces in the rechargeable electrochemical storage cell.

1. A porous insulating sheet adapted to be installed between and to provide separation between a pair of electrodes of a rechargeable electrochemical energy storage cell, the porous insulating sheet comprising:
a polymeric insulating sheet-forming material formed into the porous insulating sheet, the porous insulating sheet having a quantity of a performance enhancing isolated or synthesized supplement incorporated therewith, the porous insulating sheet adapted to be disposed in an acidic electrolyte between a positive electrode and a negative electrode engaged by an electric potential sufficient to provide an electric current therebetween, and wherein the quantity of the performance enhancing supplement incorporated in the porous insulating sheet is an amount sufficient to effect at least one performance enhancement of the rechargeable electrochemical energy storage cell selected from the group consisting of a reduction of metal transfer within the treated cell, a reduction of gas evolution from the treated cell, a reduction in water consumption by the treated cell, an increase in on-charge potential of the treated cell, a reduction in corrosion of the positive electrode of the treated cell, a reduction in self-discharge of the treated cell, and combinations thereof, when compared to performance of a porous insulating sheet that does not incorporate the performance enhancing isolated or synthesized supplement.
