​The development of sodium–oxygen batteries with high round-trip efficiencies is hindered by the short cycle lives. Sodium dendrite formation and oxygen crossover are identified as two major issues. By employing an ion selective membrane, the cycle life of sodium–oxygen batteries has been greatly improved.​
