Abstract

Li-SO₂ batteries have a high energy density but bear serious safety problems that are associated with pressurized SO₂ and flammable solvents in the system. Herein, a novel ambient Li-SO₂ battery was developed through the introduction of ionic liquid (IL) electrolytes with tailored basicities to solvate SO₂ by reversible chemical absorption. By tuning the interactions of ILs with SO₂, a high energy density and good discharge performance with operating voltages above 2.8V were obtained. This strategy based on reversible chemical absorption of SO ₂ in IL electrolytes enables the development of the next generation of ambient Li-SO₂ batteries.
