78964 - Electrochemistry T

Academic Year 2023/2024

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Chemical and Biochemical Engineering (cod. 8887)

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.

Teaching methods

Frontal Lessons, exercises and computer simulation of selected parts of the course


Assessment methods

Written examination (three exercises to be solved and two open questions, 3 hours available for the exam) concerning topics discussed during the lessons.

6 maximum points will be awarded for each exercise / question. In addition, 3 additional points will be awarded: 1 for those who have answered both open questions, 1 for the ability to express with appropriate scientific terms and to orient themselves in the context of the course topics, 1 for the orderly and legible execution of the exercises and written text.

Official appeals will be set (see Alma Exams) or, possibly, appeals at the request of a suitable number of students. Requests should be sent by email.
