Rechargeable Non-Aqueous Metal-Oxygen Batteries : Royal Society of Chemistry : 9781839164279 : 1839164271 : 28 Feb 2024 : Metal-oxygen batteries have the potential to exceed the stored energy of today's most advanced lithium-ion cells. However, their recharge and cyclability efficiency pose a major challenge to bringing this technology into practical application, as does improving our fundamental understanding of the electrochemistry and chemistry inside the cell. Li-O2 and Na-O2 are the most reported types of metal-oxygen cells but there has also been much recent work on K, Ca and Mg-O2 systems in non-aqueous electrolytes, which present different challenges and opportunities in terms of the stability and safety of the metal electrode. A critical examination of the state-of-play of metal-oxygen batteries is required to identify the major obstacles that remain in developing practical systems. This volume brings together a wide range of scientists working on metal-oxygen batteries to ex
