摘要：

The addition of potassium superoxide (KO2) into the electrolyte for Li-air battery was proved to be an effective screening method to examine the stability of the solvents against superoxide anion radicals (O-2(center dot-)). It was also confirmed that the coupled compound between Li+ and O-2(center dot-), namely LiO2 center dot, was highly reactive for many solvents to decompose themselves. Specific ionic liquid and dimethylsulfoxide, selected solvents by the KO2 screening test, actually performed stable operation of Li-air battery. (c) 2012 The Electrochemical Society.
