Synergistic Effect of Vanadate and Nanoclay Hybrid Inhibitor on the Self-Corrosion and Discharge Activity of Al Anode in Alkaline Aluminum-Air Batteries

The inherent safety and low cost of aqueous aluminum-air (Al-air) batteries have attracted significant attention. However, their lifespan is constrained due to the formation passive layers severe self-corrosion Al anode. This work addresses anode issues using an innovative design strategy by adding vanadate nanoclay modify interaction electrolyte. results shown that each vanadate, nanoclay, a hybrid combination both reduced corrosion considerably. additive provided highest inhibition efficiency 72.6% compared 57.6% for vanadium 69.8% nanoclay. anode’s anodic capacity density reached 81.4% 2426 mAh.g ?1 inhibitor. Electrochemical microscopical analysis indicated additives was attributed protective film formed on surface. Therefore, this technique has potential application in Al-air increase increasing
