[Lead-acid batteries](https://www.materialinsights.org/energy/e_lead_acid/) (energy) and [Sulphuric acid](https://www.materialinsights.org/chemicals/sulphuric_acid/) (chemical): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Sulphuric acid → Lead-acid batteries*

Building or running Lead-acid batteries needs sulphuric acid.

### 2. Price link: electrolyte

*Cost and price · Moderate · Both ways*

Each cell is filled with dilute sulphuric acid, and spent acid is recovered in recycling. Acid is a small cost, so the acid index shows only a weak link, with monthly moves at 0.08 and yearly moves at 0.36.

- **0.08** monthly change correlation
- **0.36** 12-month change correlation
- **0.23** fitted elasticity
