Programma dettagliato e risultati di apprendimento attesi

The course is meant to be both a general introduction to the fundamentals of electrochemistry (in fact, there is no previous course which covers this subject matter) and an overview of diverse applications of electrochemistry.

Course syllabus

Introduction. Short historical outline: early electrochemical technologies and the slow growth of electrochemistry as a science (a small bunch of things you should be ashamed not to know). Electrochemical systems: general structure and functioning (electrolytic and galvanic cells), with various examples, in particular: aluminium electrowinning cell; the lead acid battery.

Electrolytes and conductivity. Transport properties of electrolytes: mechanical and electrical mobility; molar and equivalent conductivity; transport number. Solid electrolytes: defects and conduction mechanisms; oxide conductors for high temperature electrochemical cells and devices; Ag and Cu halide solid electrolytes; sodium ion conductors. Case study: sodium-ion batteries

Structure of the electrode-electrolyte interphase. Models of the double layer. Galvani and Volta potential. Electrochemical thermodynamics: fundamental relationships, electrochemical potential and the Nernst equation. The electrochemical series. Pourbaix diagrams. Case studies: (a) cells with junction and electrochemical sensing; (b) thermodynamics of fuel cells.

Electrochemical kinetics. Overpotential and kinetic regimes. Butler-Volmer equation: single electron transfer processes. Low and high field approximation of the B.-V. equation; charge transfer resistance; Tafel's law. Multiple step e-transfer reaction. Mass transfer kinetics: the Nernst diffusion layer, steady-state diffusion controlled kinetics and mass transport limited kinetics. Diffusion control and mixed control regime. Mass transfer effects under transient conditions: Cottrell and Sand equations. Ionic transport and current distribution in electrochemical systems.

Electrochemical methods for the experimental study of electrode reactions. Steady state and transient techniques. Voltammetry and electrochemical impedance spectroscopy. Application examples: potentiostatic transient for the study of: (a) pitting of aluminium alloys; (b) nucleation behaviour in electrocrystallization. Electrochemical impedance characterization of polymer coated metals; failure detection of thermal barrier coatings.

A brief on electrocatalysis. The hydrogen electrode and the oxygen electrode. Electrocatalysis and electrode materials.

Electrochemical energy storage and conversion. Primary and secondary batteries. Alkaline batteries; lead-acid battery; secondary lithium batteries. Electrolytic capacitors: principles and manufacturing (briefly). Supercapacitors: principles and behaviour. Energy and power performances; experimental assessment of SC cell performance. Double layer and pseudo-capacitive effects. Hybrid devices.
Fuel cells. Historical outline. Types of fuel cells: low (polymer electrolyte membrane FC) and high temperature systems (Solid oxide FC): performances and material issues.

Electrochemistry of metals and oxides: anodic oxide films; electropolishing; low and high temperature oxidation (model of oxide film growth; Wagner's theory of oxidation).


Learning objectives


The course is meant to provide a general background in electrochemistry and coverage of some areas of electrochemical processes and technologies. Accordingly, the student is expected to acquire familiarity with the key concepts of electrochemistry and be able to critically analyze practical applications of electrochemistry, in particular use electrochemical understanding to discuss aspects of material processing and electrochemical power sources.


Note Sulla Modalità di valutazione

Evaluation and grading will be determined on the basis of homework assignments (40%) and the performance in the final writing exam (60%)

The final written exam consists of open questions (topics related to electrochemistry fundamentals) and exercises requiring the ability to do basic calculations in electrochemistry.
