I am currently strating to test materials as anodes for Li-ion battery and want to do galvanostatic charge discharge experiment using Gamry's potentiostat/galvanostat. So, what is the basic procedure to do such experiment?
Hi, what i have got from your question is that you want to test galvanostatic charge discharge performance of Li-ion battery, as your considered component is anode so you need to calculate charge/discharge capacities based on the specific weight of you anodes. Secondly, you need to know and calculate the current density (in Micro Ampere) at which you want to test your battery. It can be simply calculated as (sp. capacity of active material * actual weight of active material * c-rate).
Then you need to write the program in the user interface software provided by Gamry Instruments for the charge/discharge, you may also check some tutorial on youtube etc. for writing such program. Hope the answer will be useful for you.
best of luck,
Follow, please, some helpful Notes[1-3] and Battery Research[3] , mainly, in the Gamry site and you can find some more Gamry related infos, also.

Late catch on this, but the exact answer depends on which system you have (and for older systems, which licenses). There are charge, discharge and cyclic charge discharge experiments included in the energy technique suite of experiments. There are also constant current experiments as part of physical electrochemistry techniques (chronopotentiometry) and corrosion techniques (galvanostatic).
Dear Jacob,
Thank you for the suggestion. Our system is Gamry interface 1000. My question is about specific procedures for the software to carry out the galvanostatic charge-discharge (GCD) experiments. Where to start? Is it charging or discharging comes first? And so on . . .
It sounds like you would be best off contacting Gamry technical support directly.
