What is claimed is: 1 . A charge/discharge method of an air battery including a positive electrode, a negative electrode, and a nonaqueous electrolyte liquid containing a nonaqueous solvent and a lithium salt dissolved in the nonaqueous solvent, the nonaqueous electrolyte liquid being interposed between the positive electrode and the negative electrode, the method comprising: (1) discharging the air battery; and (2) supplying a charging liquid different from the nonaqueous electrolyte liquid from the outside to the inside of the air battery so that a discharge product generated by the discharging is desorbed from the positive electrode while being in the form of a solid. 2 . The charge/discharge method according to claim 1 , further comprising: (3) emitting the electrolyte liquid from the inside to the outside of the air battery after the discharging (1) and before the supplying (2). 3 . The charge/discharge method according to claim 1 , further comprising: (4) emitting the electrolyte liquid from the inside to the outside of the air battery after the discharging (1) and in parallel with the supplying (2). 4 . The charge/discharge method according to claim 1 , further comprising: (5) emitting the discharge product desorbed from the positive electrode in the supplying (2) together with the charging liquid to the outside of the air battery. 5 . The charge/discharge method according to claim 4 , further comprising: supplying an electrolyte liquid to the inside of the air battery after the emitting (5). 6 . The charge/discharge method according to claim 5 , further comprising: (3) emitting the electrolyte liquid from the inside to the outside of the air battery after the discharging (1) and before the supplying (2), wherein the electrolyte liquid supplied after the emitting (5) is the electrolyte liquid emitted in the emitting (3). 7 . The charge/discharge method according to claim 5 , further comprising: (4) emitting the electrolyte liquid from the inside to the outside of the air battery after the discharging (1) and in parallel with the supplying (2), wherein the electrolyte liquid supplied after the emitting (5) is the electrolyte liquid emitted in the emitting (4). 8 . The charge/discharge method according to claim 1 , wherein the charging liquid contains at least one selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), and a compound represented by the following formula (3): 9 . The charge/discharge method according to claim 8 , wherein as the at least one selected from the group consisting of the compound represented by the formula (1), the compound represented by the formula (2), and the compound represented by the formula (3), the charging liquid contains at least one selected from the group consisting of tris(2,2,2-trifluoroethyl)phosphite, tris(2,2,2-trifluoroethyl)phosphate, tris(1,1,1,3,3,3-hexafluoro-2-propyl)phosphite, tris(2,2,2-trifluoroethyl)borate, and tris(hexafluoroisopropyl)borate.
