PROBLEM TO BE SOLVED: To lower the decomposition voltage of lithium peroxide or lithium oxide during charge reaction.SOLUTION: A lithium air battery, i.e., an electrochemical cell 10, includes a negative electrode 14 capable of storing and releasing lithium ions, a non-liquid permeable solid electrolyte 18 provided on the surface of a positive electrode 20 facing the negative electrode 14, a first nonaqueous electrolyte E1 filling between the solid electrolyte and the negative electrode, and a second nonaqueous electrolyte E2 filling between the solid electrolyte and the positive electrode. The first nonaqueous electrolyte E1 is an ionic liquid (electrolyte A) containing a supporting salt of lithium. The second nonaqueous electrolyte E2 is an ionic liquid containing a supporting salt of lithium, and a radical compound having a nitroxyl radical part (e.g., 4-methoxy-2,2,6,6-tetramethyl-1-piperidinyl oxy(MeO-TEMPO)). |
