Kind: research · Impact: low

## In brief

- A Nature Communications paper reports that preferential anion adsorption can stabilise the electrolyte-copper interface in initially anode-free lithium-metal batteries.
- The work targets unstable interfacial reactions at Cu current collectors, which limit these batteries.
- The study is described as facet-dependent, meaning the effect depends on the crystal facet of the copper surface.

## Why it matters

Anode-free lithium-metal batteries could store more energy per unit weight, but interfacial instability at the copper current collector currently limits them. A mechanism that stabilises this interface could inform electrolyte and current-collector design.
