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

## How they are linked

### 1. Material need

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

Building or running Metal-air batteries needs zinc.

### 2. Price link: anode metal

*Cost and price · Weak · Both ways*

Zinc-air cells oxidise zinc powder, and zinc is their main material cost. The primary battery proxy covers many chemistries, so it shows no link to zinc, with monthly moves at -0.04 and yearly moves at -0.25.

- **-0.04** monthly change correlation
- **-0.25** 12-month change correlation
- **0.14** fitted elasticity
