Abstract
The present invention discloses an aluminum-air composite battery and a preparation method, which relates to the technical field of batteries. The present invention includes an aluminum-ion battery anode, an aluminum-ion battery cathode, an aluminum-air battery cathode and an alkaline electrolyte; MnO2, SiO2, TiO2, Mg, Ga, Sn, Bi, Zn and Al are mixed in proportion, melted in an inert gas environment, then refined and poured to prepare the aluminum-ion battery anode; α-MnO2, nickel oxide and anhydrous ethanol are mixed and calcined, and then mixed with Ketjen black, activated carbon, polytetrafluoroethylene dispersion and anhydrous ethanol into pulp; and the pulp is coated on a nickel fiber felt, pressed by a die and dried to prepare the aluminum-ion battery cathode.
