Liquid electrolytes for electrochemical cells, electrochemical cells and implantable medical devices

摘要

A liquid electrolyte for use in an electrochemical cell having an alkali metal anode is provided. The liquid electrolyte comprises 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, 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.
