Waterproof Emergency No Rechargeable Light Aluminum Air Battery 1. Description (1) Why is aluminum used in batteries? In addition, aluminum possesses a higher volumetric capacity than Li, K, Mg, Na, Ca and Zn owing to its high density (2.7 g/cm3 at 25 °C) and ability to exchange three electrons. This again means that the energy stored in aluminum-batteries on a per volume basis is higher than that in other metal-based batteries. Product name Aluminum Fuel Battery Size 130*19
