Abstract
The invention provides novel non-aqueous electrolyte compositions comprising: a) one or more sodium-containing compounds; and b) a solvent system which comprises: i) a first solvent component which comprises one or more organo carbonate-based solvents; and ii) a second solvent component which comprises one or more surfactants in an amount of >0.5 to ≤10% by weight of the solvent system,

A sodium-ion cell comprising a negative electrode, a positive electrode, and a non-aqueous electrolyte composition comprising:
- a) one or more sodium-containing salts selected from sodium tetrafluoroborate (NaBF4), sodium hexafluorophosphate (NaPF6), sodium bis(fluorosulfonyl)imide (Na(SO2F)2N), and sodium bis(trifluoromethanesulfonyl)imide (C2F6NNaO4S2);
- and
- b) a solvent system which comprises:
- i) a first solvent component which comprises one or more organo carbonate-based solvents;
- and
- ii) a second solvent component which comprises one or more surfactants in an amount of >0.5 to ≤10% by weight of the solvent system, wherein the one or more surfactants are selected from the group consisting of:
- anionic surfactants selected from carboxylates;
- sulfates;
- sulfonates selected from docusates;
- cationic surfactants selected from RN+H3Cl−, RN+(CH3)3Cl−, diotadecyldimethylammonium chloride, cetyl pyridinium chloride, benzalkonium chloride, hexadecyl trimethylammonium chloride (CTAC) and hexadecyl trimethylammonium bromide (CTAB);
- and
- non-ionic surfactants selected from polyol esters, polyoxyethylene esters, and poloxamers.
