摘要: Sodium–oxygen batteries currently stimulate extensive research due to their high theoretical energy density and improved operational stability when compared lithium–oxygen batteries. Cell stability, however, needs be demonstrated also under resting conditions before future implementation of these In this work we analyze the effect periods on sodium superoxide (NaO2) discharge product. The instability NaO2 in cell environment is leading evolution oxygen during period decrease efficiency. addition, migration anion (O2–) electrolyte observed an important factor affecting Coulombic
