Rechargeable Non-aqueous MetalOxygen Batteries: Faraday Discussion 248

Metaloxygen batteries have the potential to exceed the stored energy of todays 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. LiO₂ and NaO₂ are the most reported types of metaloxygen cells but there has also been much recent work on K, Ca and MgO₂ 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 metaloxygen 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 metaloxygen 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 metaloxygen battery cathodes
• Metal anodes and protected interfaces
• Towards practical metaloxygen batteries
