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 electrolytes
• Materials for stable metal–oxygen battery cathodes
• Metal anodes and protected interfaces
• Towards practical metal–oxygen batteries
