Hello,
I am trying to prepare the following electrolyte: 1M NaPF6 in 1:1 EC:PC. The salt does not dissolve completely even though I have dried it and added slowly (under stirring) to the solvent mixture.
Does any one have any recommendation? (maybe giving a step by step procedure for making it - how and for how long do you dry the salt, how slowly do you add it, suppliers from which you get the salt/solvents) ?
Thanks !
Hello Roland,
I have seen this conversation. People say they have achieved full dissolution simply by drying the salt and adding it slowly to the solvent mixture under stirring. I have tried this and still cannot get a clear solution unless I filter it. I would like to know how I can avoid having to filter my solution so that I can prepare it reproducibly - at the concentration that I need -.
Thanks and regards,
Ilhame
Dry the salt in vacuum oven at 100 degrees for 24 hrs. Then once you mix the salt and solvents, keep the vial in a sonicator bath for 30mins.
