Discharge in the cell containing glyme\u2010based electrolytes can lead to formation of large cubic NaO 2 particles via a solution\u2010precipitation mechanism. While promising, high rates result in sudden death. The exact nature of the discharge product has been a matter of contention, and Na 2 O 2 has never been directly detected in a dry glyme Na\u2212O 2 cell. If Na 2 O 2 were to form during discharge in the Na\u2212O 2 cell it would have a detrimental impact on cell performance. Here we show that Na 2 O 2 forms during discharge at high overpotential in the glyme\u2010based Na\u2212O 2 batteries. Na 2 O 2 formation is confirmed by spectroscopic and electrochemical analysis and electron microscopy demonstrates that it results in thin insulating films at the electrode surface. The formation of these thin films results in rapid cell death during discharge, introducing an inherent chemical limitation to the Na\u2212O 2 battery.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/batt.202200055 Authors: Zarko P.
