Descrizione dell'insegnamento


Basic knowledge of calculus, physics and chemistry.


The course is focused on the fundamentals of electrochemistry and its technological applications, including corrosion, industrial electrochemical processes and electrochemical energy conversion and storage systems.

Learning outcomes

Knowledge and understanding

The aim of the course is to provide students with the fundamentals of electrochemistry and its technological applications, including systems for conversion and storage of corrosion, industrial electrochemical processes and electrochemistry.

Applying knowledge and understanding

After the course, the students should:
- have acquired the skills necessary to address the broad theme of electrochemical technologies, discussing in particular the most important variables, both from a thermodynamic and kinetic point of view;
- have understood the mechanisms of charge transfer and be able to describe the structure of the electrochemical interface;
- have acquired the basic tools for understanding the corrosion of metallic materials in the different environments in which they can be used;
- be able to discuss the electrochemical processes applied to industrial production;
- have understood the electrochemical devices for electrochemical energy conversion and storage systems.

Making judgements

The course provides the ability to critically address electrochemical, corrosion and energy conversion and storage problems.


The course promotes the ability of the students to expose to experts their acquired scientific knowledge in precise and formal terms and to non-specialists by using elementary concepts.

Learning skills

Students are encouraged to acquire the critical skills to deal with typical theoretical and practical electrochemical problems. They should be able to expose their acquired knowledge summarizing notions from books and slides.

Teaching Methods

The course consists of frontal lessons using slides made available to students and classroom exercises. The frontal lessons are aimed at improving students' knowledge through the presentation of theories, models and methods. Numerical and practical exercises are aimed at a better understanding of the theory.


In the final exam (oral) the topics presented during the lectures will be addressed; the results obtained during the laboratory exercises will be discussed with the possibility to solve simple numerical exercises.
