Electrolytes and Thin Films for Solid State Batteries

Battery safety is a key challenge, as is the practical implementation of batteries over a wide range of temperatures without additional heating or cooling. Solid state batteries present a solution to these challenges, providing inherently safe batteries that are stable over applicable temperature ranges.

Competitive advantage

  • Expertise in materials development
  • Analysis of conductivity and diffusion at bulk and atomic scales
  • Spectroscopic and crystallographic methods for characterising materials
  • Working towards development of all-solid-state thin film batteries

Impact

  • Understanding the role of grains and grain boundaries on bulk diffusion
  • Evaluating the type of atomic-scale diffusion
  • Linking structure to local and long-range diffusion
  • Using in situ methods to elucidate phase evolution

Successful applications

  • Developed a testing apparatus for the operando study of thin film batteries using synchrotron X-ray diffraction during operation.

Capabilities and facilities

  • Materials synthesis
  • Pulse laser deposition growth of certain electrodes
  • Access to key analytical techniques such as solid-state NMR, surface analysis and electron microscopy
  • Use of unconventional techniques such as quasi-elastic and inelastic neutron scattering
