Dr Eng. Ilona Acznik from the Łukasiewicz – Institute of Non-Ferrous Metals in Gliwice, in cooperation with a research team from the Lodz University of Technology, received a gold medal at the International Warsaw Invention Show IWIS. The researcher was awarded for the invention “High-performance lithium-ion batteries based on graphene”.  

The aim of the project was to synthesize a new electrode material constituting the anode of lithium-ion batteries. It was achieved by analyzing the physicochemical and electrical phenomena occurring during cross-linking of a graphene flake material with the addition of nanosilicon. The advantage of this solution is the use of spatial graphene structures with nanosilicon as the material of the negative electrode.

The creation of an oriented, spatial structure has strengthened the physicochemical interactions between lithium ions and the carbon structure, which enables to shorten the battery charging time and extending its life.
