Using aluminum and water to make clean hydrogen fuel August 12 2021, by Nancy W. Stauffer Laureen Meroueh PhD ''20 (pictured) and professors Douglas P. Hart and
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. Thus, since the ionic radii of Al 3+ (0.54 Å) and Li + (0.76 Å) are similar, significantly higher numbers of electrons and Al 3+ ions can be accepted by …
