Example Embodiment
[0051] Example 1
[0052] This example is intended to illustrate the electrolyte disclosed herein.
[0053] In the glove box (h 2 O 2 In 6 ), Dissolve it in an organic solution to obtain a base electrolyte.
[0054] Lithium salt concentration: 1m hexafluorophosphate (LIPF 6 );
[0055] Non-water organic solvent: vinyl carbonate (EC): mixed solvent of dimethyl carbonate (DMC) = 1: 1 (V: V);
[0056] The organic compound having a mass fraction of 0.2% is added to the substrate electrolyte, and the electrolytic solution 1 is obtained, wherein the structure of the organic compound is:
[0057]
Example Embodiment
[0058] Example 2
[0059] The electrolytic solution is disposed according to the method of Example 1, and the difference is that an organic compound having a mass fraction is 0.5% in the base electrolyte to obtain an electrolyte 2.
Example Embodiment
[0060] Example 3
[0061] The electrolyte according to the method of Example 1 is configured, and the difference is that the organic compound having a mass fraction is 1% in the base electrolyte to obtain an electrolyte 3.
