How are we Testing Electrochemical Cells and What are we Testing For?
Potentiostats are used to conduct electroanalytical tests on the electrochemical cells by measuring the potential and/or current over the cell. The main test that we are focusing on for our design is a Cyclic Voltammetry (CV) test.
CV Tests measure the current in cells when applied with an excess of voltage. This works by cycling the potential (voltage) through the cell, and measuring the current that results from the cycle. These are often measured against a reference electrode that maintains a constant potential.
We control our potentiostat using an Arduino Due microcontroller. This allows the user to set their minimum and maximum voltages for the test, which determines the potential sent through the cell. The Arduino can also receive and record the measured current.
