Example Embodiment
[0058] Example 1
[0059] Mix the first salt NaAlCl in a predetermined ratio 4 With the second salt NaAlI 4 , And confirm the melting point. Confirmed press NaAlCl 4 : NaAlI 4 The melting point of the electrolyte produced by mixing with a molar ratio of 9.5:0.5 is 150℃, and the melting point is higher than NaAlCl 4 Single salt (Comparative Example 1) or NaAlI 4 The single salt (Comparative Example 2) is low, and the ion conductivity is suitable for battery implementation.
Example Embodiment
[0060] Example 2
[0061] Mix the first salt NaAlCl in a predetermined ratio 4 With the second salt NaAlI 4 , And confirm the melting point. Confirmed press NaAlCl 4 : NaAlI 4 The melting point of the electrolyte produced by mixing with a molar ratio of 9:1 4 Single salt (Comparative Example 1) or NaAlI 4 The single salt (Comparative Example 2) is low, and the ion conductivity is suitable for battery implementation.
Example Embodiment
[0062] Example 3
