Aluminium-air provides the overall best balance of performance, lightweight, safety and reliability versus Zn-air and Li-air. The strategic materials selection implies that, while significant cost reduction in storage is paramount and materials make up the largest portion of system cost, it is critical that storage devices utilize materials that are both, low in cost and abundant.

The Aluminium–air battery is an attractive candidate as a power source for electric vehicles (EVs) because of its high theoretical energy density (8,100 Wh/kg), which is significantly greater than that of the state-of-the-art Lithium-ion batteries. However, some technical and scientific problems preventing the large-scale development of Aluminium–air batteries have not yet been resolved and are still under current R&D programs in the company.
