Rechargeable Non-aqueous Metal–Oxygen Batteries

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 exchange ideas on the challenges and prospects in this field. In this volume the topics covered include:Mechanism of ORR and OER in non-aqueous electrolytesMaterials for stable metal–oxygen battery cathodesMetal anodes and protected interfacesTowards practical metal–oxygen batteries
