Study identifies halogen-free superhalogen electrolytes for Li-ion batteries

Green Car Congress

Most electrolytes currently used in Li-ion batteries contain halogens, which are toxic. An in-depth study based on first-principles calculations by researchers at Virginia Commonwealth University has shown that the anions of commercially available electrolytes for Li-ion batteries are all superhalogens. Several halogen-free electrolytes are identified among which Li(CB 11 H 12 ) is shown to have the greatest potential.
