Abstract:
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.

Claim (Index 46):
A porous insulating sheet for use between a pair of electrodes of a rechargeable electrochemical energy storage cell, and when in use placed between and providing separation between the pair of electrodes, the rechargeable electrochemical energy storage cell adapted to include multiple assemblies of alternating positive and negative electrodes interspaced by insulating sheets, the porous insulating sheet comprising:\n a polymeric insulating sheet-forming material formed into the porous insulating sheet; and an isolated supplement, a synthesized supplement and a migratory compound, individually or in combination, included with the porous insulating sheet, for enhancing performance of an electrochemical cell being in particular, although not exclusively, the rechargeable electrochemical energy storage cell; the isolated supplement, the synthesized supplement, and the migratory compound each comprising compounds that have molecules including at least one hydrophobic hydrocarbon chain and a hydrophilic portion; the isolated supplement consisting essentially of one or more isolated compounds having the molecules including the at least one hydrophobic carbon chain and the hydrophilic portion, the one or more isolated compounds obtained by extraction from one or more natural materials, the one or more isolated compounds corresponding to compounds included in a non-polyisoprene portion of a solid material obtainable from a natural elastomer of  Hevea brasiliensis  trees, inclusion of the natural elastomer with the one or more isolated compounds thereby being avoided; the synthesized supplement consisting essentially of one or more synthesized compounds having the molecules including the at least one hydrophobic hydrocarbon chain and the hydrophilic portion, the one or more synthesized compounds being industrially prepared or manufactured chemical compounds, and when in use the one or more synthesized compounds providing at least one substantially same performance enhancing function as the one or more isolated compounds obtained by extraction, the one or more industrially prepared or manufactured chemical compounds when in use not interfering disadvantageously with functioning of the electrochemical cell; the migratory compound consisting of one or more ingredients, the one or more ingredients consisting essentially of one or more compounds having the molecules including the at least one hydrophobic hydrocarbon chain and the hydrophilic portion, the one or more ingredients included with a natural and a processed material, individually or in combination, wherein the one or more ingredients consist of compounds other than natural and cured polyisoprene, and when in use the one or more ingredients providing the at least one substantially same performance enhancing function as the compounds obtained by extraction and the industrially prepared or manufactured compounds; the porous insulating sheet, including the isolated supplement, the synthesized supplement and the migratory compound, individually or in combination, adapted to provide confirmation of inclusion and presence therewith of the compounds that have the molecules including the at least one hydrophobic hydrocarbon chains and the hydrophilic portion by producing a foam, whereby a portion of the porous insulating sheet is placed in an H2SO4 electrolyte and, upon placing of the portion of the porous insulating sheet therein, soaking for a period of time of less than one week in, and agitating by shaking in the H2SO4 electrolyte under an atmospheric pressure between 80 and 105 kPa, and at a temperature between 10 degrees and 100 degrees Celsius, the foam so produced confirming inclusion and presence therewith of the compounds that have the molecules including the at least one hydrophobic hydrocarbon chains and the hydrophilic portion in a concentration sufficient to effect performance enhancement; wherein the performance of the electrochemical cell is enhanced by the porous insulating sheet including the isolated supplement, the synthesized supplement and the migratory compound, individually or in combination; and the performance enhancement of the electrochemical cell including a reduced metal accumulation on a negative electrode of the electrochemical cell or a palpable elevated electric potential of the negative electrode of the electrochemical cell, or both, when the porous insulating sheet is placed in and used in the electrochemical cell and when compared to performance of the electrochemical cell adapted for use without the porous insulating sheet placed therein nor used therein, or when compared to an electrochemical cell adapted for use as a control cell and that is equivalent to the electrochemical cell except that the porous insulating sheet is not placed therein nor used therein.
