Fluorine-free salts for aqueous lithium-ion and sodium-ion battery electrolytes

摘要: A first generation of fluorine-free lithium and sodium salts based on the concept pseudo-delocalized anions has been synthesized with both high purity yield using water as solvent in reaction medium. The have fully characterized by Raman FT-IR spectroscopies, thermogravimetry, X-ray crystallography to reveal basic properties terms thermal stability solubility well local, mainly ion–ion interaction dictated, coordination details ionic conductivity electrochemical window measurements aqueous electrolytes. Together a picture is created salts' promise components electrolytes – primarily aiming at application low voltage lithium-ion batteries (LIBs) sodium-ion (SIBs).
