Embodiment 1
[0035] The aluminum-air battery electrolyte mother solution in this embodiment is 4 mol / L sodium hydroxide solution, the corrosion inhibitor is sodium thiosulfate, and the concentration in the electrolyte is 0.005 mol / L. The preparation method of the electrolytic solution is as follows: prepare a sodium hydroxide solution with a concentration of 4 mol / L, cool to room temperature, add accurately weighed sodium thiosulfate, stir and dissolve completely.
[0036] The static self-corrosion rate of the Al-0.1Sn-0.1Ga aluminum anode alloy in the electrolyte prepared in this embodiment was tested by the gas collection method, and the test time was 30 minutes. The results are shown in Table 1 below. Using a three-electrode system to test the open circuit potential of the Al-0.1Sn-0.1Ga aluminum anode alloy in the above electrolyte and at 25°C, 100mA / cm 2 The working potential curve under the current density, the results are detailed in figure 1 , figure 2 . The self-corrosion rat...
