LIQUID ELECTROLYTE FOR AN ELECTROCHEMICAL CELL
First Claim
1. A liquid electrolyte for use in an electrochemical cell having an alkali metal anode, the liquid electrolyte comprising an additive formed of at least one selected from the group comprising:
- a tautomer;
an alcohol having the formula R—
OH, where R is one selected from the group comprising an unsaturated carbon chain having at least two carbon atoms, a saturated carbon chain having at least one carbon atom, tetramethylammonium hydrogen phthalate, and an aromatic carbon chain;
a sugar; and
an acid selected from the group comprising nitric acid, sulfuric acid and sulfuric acid partially substituted with an ion of said alkali metal material.
