Research topic

This is a doctoral cotutelle project between Deakin University (Australia) and Université de Bordeaux (France) under the AUFRANDE Program.

The successful candidate will sign a 36-month employment contract with French National Centre for Scientific Research (CNRS) - Institute of Condensed Matter Chemistry in Bordeaux (ICMCB - UMR5026) and be enrolled as a PhD candidate at both Université de Bordeaux (France) and Deakin University (Australia).

Twelve months of the total period of the program will be spent at Deakin University, with the remainder of the program based at Université de Bordeaux (France).

International mobility is a core feature of the program. The Australia-France Network of Doctoral Excellence (AUFRANDE) is a unique PhD training program co-funded by the European Union and bringing together 37 research centres in France and Australia. Besides a residential year in Australia, the successful candidate will be part of a cohort of 64 PhD fellows and will participate in regular events where they will share common experiences and build a sustainable community, laying a strong foundation for long-term impact on future collaborations and careers.

Increasing energy demands throughout society, e.g. for transport, renewable energy storage etc., requires a continued improvement in the energy density of lithium ion batteries. Improving the safety of these devices is also critical, particularly for electric vehicle (EV) applications. In the drive to develop stable, high energy density lithium ion batteries it is essential to explore both new electrode materials, such as lithium metal anodes and high voltage cathodes, combined with new electrolytes, and to overcome the current challenges associated with control of the interfaces between these different components.

This project will use spinel type manganese-rich compounds, bare or modified at their surface, as the positive electrode to allow realization of high voltages. These will be combined with new solid-state electrolytes because solid electrolytes are highly advantageous for safety and stability. The new electrolyte materials, based on organic ionic plastic crystals (OIPCs), are composed entirely of ions and thus have the advantage of being inflammable and having negligible vapor pressure. The chemical, physical and electrochemical properties of the OIPCs can be modified by changing the nature of the cation and anion and thus there is significant scope for optimizing the materials and the device performance.

In order to utilize the combinations of novel cathode and electrolyte materials, this project will address the challenges of maintaining both conduction and mechanical properties over long range cell cycling. This will be achieved by studying the interfacial reactions occurring at the electrode/electrolyte interface, how this evolves with cycling, and how it changes depending on the nature of the electrode and electrolyte materials. This strategy will allow us to optimize both the electrode material and the electrolyte for improved battery performance and extended life.

The project will be performed in close collaboration between IFM at Deakin University (Australia) and Tecnalia (France), both experts in the development of electrolytes, and ICMCB at Bordeaux University (France) expert in the development of electrode materials for batteries.

Project aim

The overarching aim of this project is the:

  • investigation of the thermal and transport properties of new plastic crystal electrolytes and their combination with metal ion salts.
  • investigation of the compatibility of the plastic crystal-based electrolytes with different high voltage cathode materials: electrochemical studies including coin cell investigation, post-mortem investigations using various spectroscopic and diffraction methods.
