[Aluminium](https://www.materialinsights.org/commodities/aluminum/) (commodity) and [Metal-air batteries](https://www.materialinsights.org/energy/e_metal_air/) (energy): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Aluminium → Metal-air batteries*

Building or running Metal-air batteries needs aluminium.

### 2. Price link: anode metal

*Cost and price · Weak · Both ways*

Aluminium-air cells offer very high energy but consume their aluminium plates, which must be recycled at smelters. The proxy shows no link to aluminium, with monthly moves at -0.07, since aluminium-air is still a niche.
