Facet-dependent anion adsorption for electrolyte-Cu interfacial stability in initially anode-free Li-metal batteries
Nature · By Jeong-A Lee ·
The 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.
