NanoMILiB - Nano-Materials for Improved Lithium Batteries

The current project is an important extension of Li-ion battery research at the University of Oslo and addresses fundamental issues connected with nanostructuring and solid electrolytes that have to be understood and mastered in next generation high energy-high power batteries for the transportation sector.

About the project

The transport properties (electrons, ions) may change dramatically at the nanoscale, e.g. a layer of an isolator may still be sufficiently conducting for use as thin conducting separator. In the project we address transport properties in general, with focus on the solid electrolyte (being a key component in our efforts on all-solid-state-Li-ion-batteries), and also on the electrodes (intercalation, kinetics, volume work).

New knowledge, directly of relevance for technology, will be derived through studies of model materials, which actually will be real, chemically pure materials used in today´s technology (e.g. LiFePO4 for catode, LLT for electrolyte). These will be synthesized (fabricated) as bulk specimens, nanoparticles and thin films using a battery of synthesis routes to our disposal. Furthermore, these materials will be chemically modified as to incorporate various types of defects that are highly likely to affect the transport properties. Through a new collaboration with the strong research group in ionics at UiO, we will investigate Li-ion transport as function of defect situation as well as function of particle size/thin film thickness.

The project will fully integrate the synthesis/characterization studies with computational materials science. The latter will focus on how transport is influenced by defects and particle size at the nanoscale. We will finally use the novel opportunity to strengthen international links to European battery industry (via ongoing EU projects) and to directly interact with our international research partners in the field of atomic layer deposition, solid state chemistry and computational material science.
