experiment example 1
[0030] In order to analyze the characteristics of the electrolyte solution composition, a 2000m 2 Activated carbon with a specific surface area of / g is coated on the current collector with a thickness of 60 μm to be used as a positive electrode, which will have a 10m 2 Hard carbon (hard carbon) with a specific surface area of / g was coated on the current collector in a thickness of 25 μm to be used as a negative electrode.
[0031] In addition, according to the exemplary embodiment (Example 1) of the present invention, in the composition of the electrolyte solution, 1.0 to 1.5 mol / L of LiPF 6 was used as a solute, and a material having the following composition ratio was used as a solvent: PC:DEC=3±0.05:7±0.05.
[0032] In order to compare with the characteristics of the electrolyte solution according to the embodiment of the present invention, a control group was prepared and then tested, and in the control group, 1.0 to 1.5 mol / L of LiPF was used 6 As a solute, and as...
experiment example 2
[0040] In Experimental Example 2, using a mixture of PC and DEC having different composition ratios as a solvent of the electrolytic solution, under the same conditions as Experimental Example 1, the resistance characteristics according to temperature were compared.
