Rechargeable non-aqueous metal-oxygen batteries Faraday Discussion

11 - 13 September 2023, York, United Kingdom



Join us in York in September 2023 for this addition to our Faraday Discussion series. For over 100 years and 300 meetings, Faraday Discussions have been the forefront of physical chemistry. Many of these Discussions have become landmark meetings in their field.
This meeting is for established and early-career scientists, post-graduate students and industrial researchers interested in rechargeable non-aqueous metal–oxygen cells.
Given the intensive worldwide research efforts over the past decade in these cells and the resulting improvements in fundamental understanding of the associated electrochemistry and chemistry, the unique format of the Faraday Discussions will allow for in-depth discussions of the major challenges that must be overcome to bring this technology into practical application. The meeting will bring together the wide range of scientists working on metal–oxygen batteries and allow opportunities to establish new collaborations.
On behalf of our committee, we look forward to welcoming you to York.

Chair, 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.

The Discussion will focus on the following four themes: 
  • Mechanism of ORR and OER in non-aqueous electrolytes
ORR and OER mechanisms in non-aqueous electrolytes are sensitive to solvent choice, salt, temperature, electrode substrate and water content. Metal oxide nature plays a significant role in the functioning of an electrochemical cell, and ultimately, the battery device. Understanding this chemical environment is a key step in developing practical metal–oxygen cells. Discussion in this section will focus on understanding ORR and OER using fundamental or well-characterised electrode systems, and the use of redox mediators and how to obtain high coulombic and charge–discharge efficiencies.
  • Materials for stable metal–oxygen battery cathodes
In this session, focus will shift towards the development and characterisation of practical cathodes and understanding how to generate reversible reactions within and upon applied electrode architectures. Key discussion points will include material interface design, morphology of cathode materials, the use of carbon as an electrode substrate, reproducible cell testing and chemical and electrochemical characterisation techniques.
  • Metal anodes
Major issues around safety, reversible stripping and plating and dendrite formation have been known for some metal anodes for over 30 years. Key challenges in the field include developing stable anode–electrolyte interfaces and practical anodes, the use of solid electrolytes and safely achieving high current densities > 1 mA cm-2. In this session, discussion will cover dendrite prevention, solid-state coatings and electrolytes, as well as how to achieve a stable solid–electrolyte interphase and minimise side reactions.
  • Towards practical metal–oxygen batteries
This session will discuss state-of-the-art metal–oxygen cells in terms of cyclability and durability. Demonstrating lab science as a practical technology is a key challenge, and discussion will be at the cutting edge of electrochemistry, electrochemical engineering and materials science. Key discussion points will include the metrics required at a materials level to obtain competitive performance with state-of-the-art Li-ion batteries, and how to develop membranes and air treatment to minimise water contamination in these open systems.

Format of the Discussion

Faraday Discussions have a special format where primary research papers written by the speakers are distributed to all participants before the meeting, and most of the meeting is devoted to discussing the papers. All delegates at the meeting, not just speakers, have the opportunity to make comments, ask questions, or present complementary or contradictory measurements and calculations during the discussion sessions. In addition, there is a dedicated poster session where further discussion takes place. The research papers and a record of the discussion are published in the journal Faraday Discussions.

The Royal Society of Chemistry is keen to encourage and enable as many people as possible to attend our events, to benefit from the networking opportunities and the chance to hear talks from leaders in the field. If you would like to discuss accessibility, please contact us to discuss your requirements so that we can enable your attendance.

Abstract Submission

Oral Abstracts

A full research paper containing new unpublished results always accompanies oral presentations at Faraday Discussions. Submit an oral/paper abstract by January 2023 if you wish to be considered for an oral presentation and associated published paper. The oral/paper abstract should outline current research in progress. Authors of the selected abstracts must then submit a full research paper with a significant amount of new, unpublished work by May 2023

The research papers are reviewed upon submission and are sent to all delegates 4 weeks before the meeting so they can be read in advance. At the meeting the presenting author is allowed five minutes to highlight the main points of their paper, and the rest of the time is for discussion. The discussion is recorded and will be published alongside the research paper in the Faraday Discussion Volume.   

Poster Abstracts 

Submit your poster abstract by July 2023. Posters are displayed throughout the meeting and a poster session is held on the first evening. The Faraday Division Poster Prize will be awarded to the best poster presented by a student at the conference.

Additional Information

Authors will be notified of the outcome of the review process within about 6 weeks of the submission deadline. The abstracts should be no longer than one A4 page in portrait layout. Please ensure you provide the details of the presenting author and indicate whether you are submitting an abstract for oral or poster presentation
