PROBLEM TO BE SOLVED: To furthermore improve charge/discharge cycle characteristics.SOLUTION: A nonaqueous battery 20 of the present invention includes an ion conduction medium 27 in a space between a positive electrode 22 and a negative electrode 23. The ion conduction medium 27 contains: a solvent of carbonates such as an ethylene carbonate, a dimethyl carbonate, and an ethyl methyl carbonate; a supporting electrolyte such as LiPF; and a compound including B-H or Si and including one or more hexafluoro isopropyl groups. The compound may comprises at least one of sodium tris(1,1,1,3,3,3-hexafluoroisopropoxy)borohydride and tetrakis(1,1,1,3,3,3-hexafluoroisopropoxy)silane. The ion conduction medium 27 favorably contains the compound in the range from 0.5 mass% or more to 10 mass% or less. |
