Disclosed in the present application are a flow battery device for recovering Li+ and a recovery method. In the present invention, a waste LiFePO4 solid wrapped by a porous PTFE filter membrane is placed on one side of a positive electrode electrolyte of a flow battery, such that the positive electrode electrolyte in an oxidized state can penetrate through the filter membrane to be in full contact and react with LiFePO4. The electrolyte of the positive electrode oxidizes LiFePO4 into Li+ and FePO4 by means of an oxidation reaction, and the generated Li+ enters the electrolyte and penetrates through the membrane to reach one side of the negative electrode in the form of a supporting electrolyte; in addition, the membrane material has strong selectivity for Li+, ensuring that the other ions cannot penetrate through the membrane. The electrode surface of the negative electrode of the flow battery is coated with a hydrogen evolution catalyst to perform a hydrogen evolution reaction and recover hydrogen, thereby achieving the dual purpose of recovering Li+ and producing hydrogen by means of electrolysis. A new LiFePO4 electrode material is re-obtained by means of calcination, etc., from the FePO4 produced at the positive electrode and the Li+ product obtained at the negative electrode, and is used in a lithium-ion battery.
