Course at a Glance
The aim of this course is to give an introduction to the electric circuit theory and to the electrochemical techniques in order to allow the students to correctly perform and interpret the measurements. The course will start from lumped circuits basics and moving through transient and frequency analyses of linear circuits. Basics of electrochemical measurements and typical measurement configurations will be introduced. Finally, lumped element modelling of typical equivalent circuits will be discussed and examples of simulations by
common tools (Spice, EC-Lab) will be performed. The course will comprehend some hands on experience on potetiostat and battery analyser as well.
