Aluminium-ion batteries (AIB) are a class of in which ions serve as . Aluminium can exchange three electrons per ion. This means that insertion of one Al is equivalent to three Li ions. Thus, since the ionic radii of Al (0.54 ) and Li (0.76 Å) are similar, significantly higher numbers of electrons and Al ions can be accepted by cathodes with little damage. Al has 50 times (23.5 megawatt-hours m the energy density of Li-ion batteries an.

The islands of Tuvalu are narrow atolls composed of coral, so a football field could only be located at the broadest part of the main island of . The football field on Tuvalu is built on a base, with river clay shipped in from to create a surface on which grass has grown. This improved the football field's condition, although the surface remains hard and is not uniformly flat.
