High Rate Lithium Ion Energy Storage

Lithium ion batteries that can be charged and discharged at high rates can play a critical role in stabilising electricity grids with a high proportion of renewable energy generators. These devices blur the distinction between supercapacitors and batteries, and may also find applications in electrical power buffering for mass transport systems.

Competitive advantage

  • Expertise in fabrication of binder-free 3D electrodes for high rate electrodes and amorphous metal oxide electroactive materials
  • New electrochemical modelling methods that can be used to distinguish between double layer storage and Faradaic charge storage
  • Integrated experimental-modelling approach

Impact

  • High rate electrochemical storage will be critical for electrical grid stabilisation
  • Potentially lower cost alternative to electrochemical capacitors in mass transport applications

Successful applications

  • 3D porous electrodes using metal foams and 3D printed current collectors
  • Anodic titanium oxides binder-free electrodes for high-rate anodes

Capabilities and facilities

  • State-of-the-art electrochemical fabrication and characterisation facilities
  • Expertise and access to PFG NMR and solid state NMR facilities
  • Expertise in atomic scale modelling of electrode materials and electrochemical processes
