Academic Year 2018/2019

Learning outcomes

At the end of the course the student has acquired basic knowledge of electrochemistry. In particular, the student knows the thermodynamic and kinetic aspects of electrode processes and the fundamentals of transport and interactions of charged species. The student learns how to apply this knowledge in the field of electrochemical energy conversion and storage, as well as about the corrosion of materials.
