Øystein Gullbrekken
About
I am a PhD candidate in the FACET research group at the Department of Materials Science and Engineering at NTNU. I study solid state electrolytes to enable next generation battery technologies. Specifically, I work with understanding how such materials conduct Li ions and how to increase the ionic conductivity and related transport properties.
I use molecular dynamics simulations to study Li-ion transport in solid polymer electrolytes.
In addition, I do wet synthesis and characterisation of a promising solid-state oxide-based electrolyte called LLZO (Li7La3Zr2O12) to understand the phase evolution and thermodynamics during synthesis.
