I am working on the electrochromic behavior of the metal oxide thin films. But, the literature suggests various electrolyte for this work. I am confusing about this. Anyone suggests the criteria for choosing the electrolyte.
Dear Gaurav, the selection of electrolyte strongly depends on the surface morphology, porosity and active surface area of the materials used. Therefore, you can used more than one electrolyte for the same meterial because due to different synthesizing technique you get the different morphology etc. So i suggest you to used at least three electrolyte and find the best one.
Thanks.
Dear Gaurav Malik

Thanks, Pervaiz sir, for your valued suggestion. I will try with these articles.
One thing I would like to add to the above answers is that the electrolyte you use should not undergo electrolysis in the range of applied potentials that will be used for the operation of your devices. If possible, use an electrolyte that is stable in a wider range of potentials (i.e. it has a wider potential window), so as to avoid gradual poisoning of the device with the electrolysis products, which will severely limit the lifetime of the device.
