PROBLEM TO BE SOLVED: To provide a lithium air battery and a lithium ion secondary battery, which include an electrolyte in which decomposition in operating conditions during discharging and charging is suppressed.SOLUTION: A lithium air battery 1 includes: a positive electrode 11 in which oxygen is used as a positive electrode active material; a negative electrode 12 which has a negative electrode active material capable of absorbing and desorbing lithium ions; and a separator 13 which is impregnated with an electrolyte held between the positive electrode 11 and the negative electrode 12. The electrolyte includes a solvent represented by the following formula (1). (In the formula, x represents an integer of 1 to 3, m and n each represent an integer of 1 to 2x+1, a and b each represent an integer of 0 to 2, and a relation of m+n+a+b≥3 is satisfied.) |
