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 overcome these challenges by 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 the 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

• Access to key analytical techniques , solid-state NMR , surface analysis and electron microscopy
• Surface characterisation with scanning probe microscopy methods
• Use of unconventional techniques , such as quasielastic and inelastic neutron scattering
