Kind: research · Impact: medium

## In brief

- Aluminium–graphite batteries are limited by electrolyte decomposition above 2.5 V, according to the paper's abstract.
- The authors regulate chloroaluminate anions using a fluorine-rich, framework-confined quasi-solid-state approach.
- The study, published in Nature Communications, reports aluminium–graphite batteries operating past 3.0 V.

## Why it matters

Aluminium–graphite batteries are a potential low-cost, abundant-material alternative for energy storage, and the voltage ceiling set by electrolyte breakdown is a key obstacle to their practical use.
