Galvanostatic
The Galvanostatic technique sets a specified static offset current (area
corrected) whilst monitoring the potential response. Care must be taken when choosing the
offset current
a current should be picked the instrument is able to supply
for example:
Assuming the cell impedance is 1000 ohms the maximum offset current is 15mA this is calculated from maximum compliance potential ÷ cell impedance (15000 mV ÷ 1000 ohms)
Using Over sample measurements greatly improves measurement accuracy many readings are averaged for each point.
A Cell settle time delays at the test offset current it can be used to give the cell a chance to settle down after the offset current has been applied.
