Hi All,
Great forum, thank you to all that made it possible,
I need advice about making a Deep Eutectic Solvent Electrolyte
out of readily available chemicals listed here:
1. The chemicals I have available/obtainable are:
:: Choline Chloride, Zinc Chloride, Magnesium Chloride, Sodium Chloride, Potassium Chloride
:: Urea, Ethylene Glycol, Glycerol, Citric Acid, Glucose, Fructose
2. Must be non-aqueous
3. The DES Electrolyte (end product) need to have a wide electrochemical window (3+ V)
4. The DES need to be stable at a wide temp window (say -20 to +50C)
Please advise as to the best combination of the above chemicals to satisfy the above criterias,
Many thanks and keep up the good work.

seza,
Thank you for asking the question. I had no idea about DES's. So, I googled and learned some things.
Now, according to the forum rules, no one will answer you if you just share the question. You also need to say what your own answer is and why. Then, others might be able to make corrections, if any.

Thanks Sunkal,
My first question on this forum,
DES's are an interesting class of chemistry, very useful, cheap and environmentally-friendly,
the field of DES study is still in it's infancy therefore new discoveries are being made all the time,
as for my question: I think Choline chloride + Ethylene Glycol might do the trick but I am not sure
there I hope someone with more knowledge can enlighten us?

How much water is acceptable in "non-aqueous"? Several compounds listed here are hygroscopic and difficult to obtain dry.

Enthalpy, (cool name btw :))
What I mean is water should not be added to the mix but it can not be eliminated 100%.
