Boron-based anion receptors in lithium-ion and metal-air batteries

103The boron-based anion receptors as electrolyte-additives improve the lithium ion or metal-air battery cell cycle performance, lithium ion transference numbers, and ionic conductivity. These anion receptors reversibly bind to fluoride and peroxide anions, and facilitate in maintaining a stable solid electrolyte interface (SEI) at the electrode surface. In this comprehensive review, we have outlined the synthesis, computational studies, and applications of various classes of boron-based anion receptors in lithium ion and metal-air batteries.
