The invention discloses a liquid flow type lithium-air battery, which comprises a battery body, wherein anode aqueous electrolyte of the battery body is provided with an outer circulation loop consisting of a pump, a temperature saver, a liquid storage tank and a heat exchanger; the battery body is divided into two parts by a solid electrolyte membrane, one part comprises cathode metal lithium and cathode organic electrolyte, and the other part comprises an anode air electrode and an anode aqueous electrolyte; in the process of electric power generation and charging, the anode electrolyte is driven by the pump to form circular flow; when the battery temperature is too low, the heat exchanger heats the anode electrolyte; when the battery temperature is high, the heat exchanger cools the anode electrolyte; when the temperature is low, the temperature saver makes the anode electrolyte form lesser circulation which does not pass through the liquid storage tank; and when the temperature ishigh, the temperature saver makes the electrolyte form greater circulation which passes through the liquid storage tank. The liquid flow type lithium-air battery has the advantages of large battery capacity and good environmental temperature adaptability, and is flexible to use.
