Iron is fairly reactive; in moist air. it oxidizes to form rust, a mixture of iron oxides. Oxidizing acids like nitric acid react with iron to form a passivating layer on the surface of the iron; this passivating layer protects the iron underneath from further attack by the acid, although the brittle oxides of the layer can flake off and leave the interior metal exposed.
Aluminium-ion batteries are a class of rechargeable battery in which aluminium ions serve as charge carriers.Aluminium can exchange three electrons per ion. This means that insertion of one Al 3+ is equivalent to three Li + ions.
