The project was carried out in the period from 31.3.2019 to 31.12.2022. The project was carried out in cooperation with the International Iberian Nanotechnology Laboratory (INL) Braga Portugal, which made its laboratories and equipment available to the BUT staff. The project focused mainly on the study of materials and optimization of electrodes for Li-S and Na-ion batteries, as well as on the testing of electrolytes. In total, within the project, 6 impacted publications were published, 7 non-impacted publications listed in the Scopus database and the project participants attended 9 international conferences. For example, within the project, anode materials for Na-ion batteries based on Na2Ti3O7 (NTO) were tested, the synthesis was also carried out at Brno University of Technology. At the same time, within the project, MOF-based materials were tested for cathodes of Li-S batteries (10.1016/j.est.2019.101113, 10.1016/j.est.2022.104419, 10.1039/d2ra03301a) and Na-ion batteries (10.1016/j.matchemphys.2021.125584). Li-S battery research has also tested the effect of different types of binders in electrode fabrication, including in a laboratory pouch cell format (10.3390/ma14195578). The outputs of this project have been followed up in newly supported projects such as OP JAK Eco&Store or in the TAČR project Advanced materials for lithium and post-lithium battery electrolytes (EllyteMat).
