Important results from the project
The purpose of the project was to carry out a feasibility study on the design of catalytically active, corrosion-resistant multicomponent coatings to reduce the maintenance needs of batteries. The goal was to design a coating that work as a catalyst to recombine hydrogen and oxygen to water and that can be scaled up in an industrial environment. In the study, catalytic activity of the coatings has been demonstrated and its corrosion resistance has been evaluated with good results.
Expected long term effects
The results show that it is possible to grow multicomponent coatings where the corrosion resistance can be controlled by variations in the composition of the coating. The coatings show an electrocatalytic activity in oxygen reduction reactions. The project provides a foundation for continued studies where more material systems can be studied and provide a fundamental understanding of the coatings´ properties and performance. In the long term, the coatings can be used in energy systems such as batteries and fuel cells.
Approach and implementation
The project was a collaboration between Linköping University (LiU) and RISE KIMAB. Within the project, multicomponent coatings of varying composition have been coated on substrates with a PVD technology at LiU. The structure of the coatings has been characterized at both LiU and RISE and the electrocatalytic activity and corrosion resistance were analyzed at RISE. The arrangement has worked very well, even though the situation with Covid-19 made certain trips impossible and some restructuring of the project had to be carried out.
