Embodiment Construction

[0013] Such as figure 1 , a new type of negative electrode system for aluminum-air batteries adopts three schemes:

[0014] When the formula of the aluminum-air battery negative electrode system is Al: 97.5W%, Mg: 2.5W%, Al (purity above 99.7%), Mg (purity above 99%), the corresponding electrolyte formula is 25%KOH+10%NaCl +0.4%TiO2 (W%) forms an alkaline electrolyte with 25nm particles, which can inhibit the rate of hydrogen production and prevent the formation of Al2O3 oxide film;

[0015] When the formula of the aluminum-air battery negative electrode system is Al:95%, Ga:1%, In:1%, Sn:3%, the corresponding electrolyte formula is 5%KOH+10%NaCl+0.4%TiO2 (W% ) Alkaline electrolyte that forms 25nm particles, can work in alkaline electrolyte with a concentration below 5%;

[0016] When the formula of aluminum-air battery anode system is Al powder (99.99%), additives (Ni, Tl, In, Sn, Mn, etc.), the corresponding electrolyte formula is electrolyte: 5%KOH+10%NaCl+0.4% TiO2 (W%)...

Abstract

The invention provides a novel aluminum-air battery, which is a power generation device capable of directly converting chemical energy stored in fuel into electric energy. In recent years, high-power aluminum-air batteries are successfully applied to the fields of a fixed power station, an electric vehicle and the like, but most of the aluminum-air batteries have the disadvantages that negative electrodes are instable, the manufacturing cost is high and the discharge speed is low. The invention creatively provides the novel aluminum-air battery. The problems that the manufacturing cost of the negative electrodes is high, manufacturing and production are difficult, the reaction time is short for platelike negative electrodes, the aluminum-air batteries are not suitable for a high-capacity output product and the discharge speed is low are solved.
