Ionic liquids key to sustainable energy storage

High-capacity energy storage systems are an important part of the renewable energy transition and can be realised using RTILs, room temperature ionic liquids, as electrolytes.
A research team from University of Tartu, Estonia, recently used beamline FlexPES to study the stability of RTILs for such applications.

Oxygen cycling reveals path to next-gen ferroelectric devices

Research is heating up to achieve greater fundamental understanding of the mechanism of ferroelectricity in hafnia-based materials, a crucial step in the development of next generation devices. New findings from the University of Groningen (RUG) in the journal Science define the key role of oxygen for greater miniaturization potential and structural stability beyond that of standard ferroelectric materials used in low-power memories. Electron microscopy and MAX IV’s NanoMAX beamline have illuminated the nature of polarization in thin films of hafnium zirconium oxide for ferroelectronics.

Modelling electrochemical potential for better Li-batteries

To understand the electrochemical potential of lithium-ion batteries, it’s important to decipher the chemical processes at electrode interfaces occurring during device activity. Using HIPPIE beamline, a research group investigated and modelled the influence of electrochemical potential differences in operando in these batteries.
