I am facing a problem in selecting a appropriate electrolyte for my Lithium sulphur battery. I have used Lithium Hexafluorophosphate salt in ethylene carbonate and dimethyl carbonate solvents. But I am unable to get a good stability and capacity. It would be a great help if some one could suggest an electrolyte with its salt and solvent that could address the above two issues. Looking forward to responses and suggestions. Thanks in Advance Sonia
