Abstract
A non-aqueous electrolyte for secondary battery, secondary battery having the same and a method of manufacturing the same are provided. The non-aqueous electrolyte includes an electrolytic salt having an electrolytic salt concentration of about 0.5 M (mol/L) to about 3.8 M (mol/L) in the non-aqueous electrolyte, a first solvent having a solubility of the electrolytic salt in a range from about 100 g to about 400 g, and a second solvent having a solubility of the electrolytic salt of less than or equal to about 1 g. The first solvent includes a coordination solvent coordinated with an ionized ion from the electrolytic salt and a free solvent that is not coordinated with an ionized ion from the electrolytic salt, and a peak area ratio of the free solvent determined by a Raman spectrum is less than about 20%.
