Purpose and goal

The purpose of the project is to create a corrosion resistant, multicomponent coating, that can act as a catalyst for applications in industrial batteries. The aim is to design a coating that can act as a catalyst to recombine hydrogen and oxygen gases to water within a battery cell, and also be up-scaled in an industrial environment. This would reduce the need of maintanance and increase the life time of industrial batteries.

Expected results and effects

The project is the starting point for the usage of multicomponent coatings with combined corrosion resistance and catalytic activity. A successful project will be the proof of concept and form the foundation for larger proposals, aiming to broaden the choices of material systems and provide in-depth knowledge on the coating properties and perfomance. In long term, the results can be used to produce nearly maintenance free industrial batteries with a life time of >20 years to be used as power supplies in remote environments.

Planned approach and implementation

Multicomponent coatings with varying compositions will be deposited onto substrates using PVD. The composition and microstructure of the coatings will be studied, and also the interface between the coating and the substrate will be analyzed, using electron microscopy, x-ray diffraction and spectroscopic methods. The coating´s corrosion resistance in battery electrolyte will be tested and the catalytic reaction studied using ir-spectroscopy.
