Battery researchers across Sweden gathered last week (19/3) to kickstart the Battery matrix at MAX IV. Researchers came from various universities in Sweden, including Chalmers University, Uppsala University, Linköping University, and Lund University. Led by MAX IV’s beamline scientists Robert Temperton and Justus Just, the workshop focus on engaging discussions for a better support toward the battery research community. Other MAX IV’s scientists and functions, including the facility’s Science Director were also present.
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.
