Type of project: national project

Duration: 2017 - 2020

Project leader: Dr Matjaž KavčičCode: ARRS J2-8167Coworkers: Assoc. Prof. Dr Matjaž ŽitnikLaboratories: Laboratory for applied X-ray spectroscopy

Cheap and sustainable battery systems are prerequisite next step towards low carbon society, where the majority of energy will be obtained from renewable sources. Batteries based on redox electroactive organic materials represent an alternative to the currently most used Li-ion batteries, mainly due to almost unlimited resources and lower production energy during synthesis. The mechanism of redox reaction will be studied with x-ray spectroscopy based on synchrotron radiation, more precisely with x-ray Raman spectroscopy. This is a hard x-ray technique that combines the sensitivity to local chemical environment of light elements with experimental advantages of hard x-rays, especially their high penetration, which is used to study light elements in bulk battery electrodes. Research work preformed within the project will help us to understand the charge transfer in organic molecules which is crucial for further optimization of batteries based on organic materials.
