Kind: research · Impact: low

## In brief

- Researchers report anion redox activity in chlorine-containing cathode materials for solid-state batteries.
- The work targets extra charge storage from anions rather than only metal-centred redox in conventional cathodes.
- Source excerpt is brief; specific materials, measurements and results are not available in the provided text.

## Why it matters

Anion redox could offer additional charge capacity in battery cathodes, which matters to materials and electrochemistry researchers exploring safer, higher-capacity solid-state batteries.
