[Flow batteries](https://www.materialinsights.org/energy/e_flow_batt/) (energy) and [Zinc](https://www.materialinsights.org/commodities/zinc/) (commodity): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Zinc → Flow batteries*

Building or running Flow batteries needs zinc.

### 2. Price link: electrode metal

*Cost and price · Weak · Both ways*

Zinc-bromine and zinc-iron flow batteries plate zinc during charging. The battery proxy is a broad US index dominated by lithium products, so it shows no link to zinc, with monthly moves at -0.03.
