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.
An electrolyte comprising a base liquid electrolyte composition and a resistance-stabilizing additive distinct from the base liquid electrolyte composition, wherein the resistance-stabilizing additive comprises at least one chemical compound selected from a chemical class consisting of a compound comprising an electron withdrawing group, an aromatic diacid salt, an inorganic salt, an aliphatic organic acid, an aromatic diacid, and an aromatic monoacid.
An electrolyte comprising a base liquid electrolyte composition and a resistance-stabilizing additive distinct from the base liquid electrolyte composition, wherein the resistance-stabilizing additive comprises a compound having an electron-withdrawing group.

An electrolyte comprising:
- a base liquid electrolyte composition;
- a first resistance-stabilizing additive;
- and
- a second resistance-stabilizing additive combined with the first resistance-stabilizing additive;
- wherein the first and second resistance-stabilizing additives are distinct from the base liquid electrolyte composition.
A method for forming an electrolyte in a battery cell for an implantable medical device, the method comprising:
- selecting a first resistance-stabilizing additive;
- combining a second resistance-stabilizing additive with the first resistance-stabilizing additive to form a resistance-stabilizing composition;
- and
- combining the resistance-stabilizing composition with a base electrolyte composition for the battery cell.
A battery comprising an electrode assembly and an electrolyte, wherein the electrolyte comprises a liquid electrolyte and a resistance-stabilizing additive distinct from the liquid electrolyte, wherein the resistance-stabilizing additive comprises at least one chemical compound selected from a compound comprising an electron withdrawing group, an aromatic diacid salt, an inorganic salt, an aliphatic organic acid, an aromatic diacid, an aromatic monoacid, and combinations thereof.
A battery comprising an electrode assembly and an electrolyte, wherein the electrolyte comprises a liquid electrolyte and a resistance-stabilizing additive distinct from the liquid electrolyte, the additive being at least one of TMA hydrogen phthalate, TBA hydrogen sulfate, phosphonoacetic acid, 2,2,2-trifluoroacetamide, trifluoromethyl vinyl acetate, phthalic acid, benzoylacetone, benzoyltrifluoroacetone, and benzoic acid.
A battery comprising an electrode assembly and an electrolyte, wherein the electrolyte comprises a liquid electrolyte and a resistance-stabilizing additive composition distinct from the liquid electrolyte, the additive composition comprising:
