Battery and Neutrons

Mission: The group activities are focused on energy materials research using neutron scattering techniques with a particular focus on materials for battery application and electrochemical energy storage. Neutron scattering investigation are complemented if needed with dielectric spectroscopy, DSC and BET analysis. 

Why neutrons:  To achieve the long-term goal of designing materials to desired properties, we need to understand and manipulate their functionality at the length, time, and energy scales of the phenomena and mechanisms involved. Neutron scattering is a powerful, non-destructive probe for the investigation of structure and dynamics in matter at nanoscale: 

  • The wavelengths and energies of thermal and cold neutrons are ideally matched to the length and energy scales in the energy-related materials that underpin current and future technologies, ranging from hydrogen storage systems to fast ionic conductors and electrolytes to materials for electric energy conversion 
  • Sensitivity of neutrons to light elements such as hydrogen and lithium is a large advantage in energy material research 
  • Particular strength of neutron scattering is neutron spectroscopy thanks to unique capability to deliver direct information in both space and time simultaneously, providing information about spatial aspects of molecular  transport and charge transfer
