Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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 2.8 V were obtained. This strategy based on reversible chemical absorption of SO₂ in IL electrolytes enables the development of the next generation of ambient Li‐SO₂ batteries.</p> </abstract>
