A resistance-stabilizing additive for an electrolyte of a battery cell in an implantable medical device (IMD) comprising:
- at least one chemical compound selected from a chemical class consisting of an electron withdrawing group, an aromatic diacid salt, an inorganic salt, an aliphatic organic acid, an aromatic diacid, and an aromatic monoacid.
An additive to an electrolyte for use in a battery cell in an IMD, the additive comprising:
- an electron-withdrawing group.
An additive to an electrolyte for use in a battery cell in an IMD, the additive being at least one of tetramethyl ammonium (TMA) hydrogen phthalate, tetrabutyl-ammonium (TBA) hydrogen sulfate, phosphonoacetic acid, 2,2,2-trifluoroacetamide, trifluoromethyl vinyl acetate, phthalic acid, benzoylacetone, benzoltrifluoroactone, and benzoic acid.
An additive composition for an electrolyte in a battery cell for an IMD comprising:
- a first resistance-stabilizing additive;
- and
- a second resistance-stabilizing additive combined with the first resistance-stabilizing additive.
A method for forming an additive composition for an electrolyte in a battery cell for an IMD, the method comprising:
- selecting a first resistance-stabilizing additive;
- and
- combining a second resistance-stabilizing additive with the first resistance-stabilizing additive to form a resistance-stabilizing composition.
