Borates vs. Aluminates: Comparing the Anion for Lithium-Ion Batteries

Abstract

Lithium borate and aluminate salts bearing a hexafluoroisopropyloxy ligand have been prepared and investigated for use in lithium-ion batteries and Cu||Li cells. Lithium aluminate salts have poorer air tolerance but Li[Al(hfip)4] gave superior battery cycling, with lower overpotentials for plating and stripping in Cu||Li cells.
