[Capacitors and supercapacitors](https://www.materialinsights.org/energy/e_supercaps/) (energy) and [Lithium iron phosphate batteries](https://www.materialinsights.org/energy/e_li_lfp/) (energy): 1 relationship.

## How they are linked

### 1. Price link: competing storage

*Cost and price · Weak · Both ways*

Supercapacitors and lithium batteries compete for short bursts of power such as braking recovery and grid frequency support. Cheaper batteries take share from capacitors. The two indices hardly move together, with monthly changes correlating at -0.03, as they are priced in separate supply chains.

- **-0.03** monthly change correlation
- **0.04** 12-month change correlation
- **2.02** fitted elasticity
