Why potential window becomes shorter in Galvanostatic Charge Discharge (GCD) compared to Cycling Voltammetry (CV)?

I use iviumsoft for CV and GCD in order to measure electrochemical properties of supercapacitor electrode material. Let's say that CV curves make pretty large shape in potential window of 0 to...

Why are side chain lengths different by 4 like hexyldecyl(HD), octyldodecyl(OD). Why don't we use symmetric side chain?

why are all side chain lengths different by 4 like hexyldecyl(HD), octyldodecyl(OD), decyltetradecyl(DT). Why don't we use symmetric side chain? I appreciate any references that show the different...
