Metal accumulation inhibiting and performance enhancing supplement and a system for delivering the supplement

A porous insulating sheet for use between a pair of electrodes of a rechargeable electrochemical energy storage cell, the porous insulating sheet consisting of:

• a polymeric insulating sheet-forming material formed into the porous insulating sheet;
• and
• an isolated supplement;
• the isolated supplement consisting of compounds isolated by extracting a portion of a material obtained from a natural source;
• the isolated supplement not including any compounds obtained by extracting a portion of a cured Hevea brasiliensis elastomer;
• the isolated supplement including a phospholipid having choline as a head group with glycerophosphoric acid;
• the quantity of the isolated supplement included in the porous insulating sheet being an effective treatment quantity;
• the effective treatment quantity being a sufficient quantity of the isolated supplement to produce a foam, as demonstrated when 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, is soaked for a period of time of less than one week therein, and is agitated 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 the inclusion and presence therewith of the effective treatment quantity of the isolated supplement;
• and
• wherein performance of the electrochemical cell is enhanced by the porous insulating sheet including the isolated supplement;
• and the performance enhancement of the electrochemical cell includes 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.
