Nature Nanotechnology, Published online: 23 April 2026; doi:10.1038/s41565-026-02152-x A molecular engineering strategy using self-assembled monolayers to modulate interfacial polarity stabilizes high-potential lithium metal batteries by regulating interfacial solvent interactions and suppressing electrolyte decomposition up to 4.7 V.

Nature Nanotechnology, Published online: 20 April 2026; doi:10.1038/s41565-026-02166-5 Electrodics is the branch of electrochemistry that studies electrode processes, such as charge dynamics, at their interface with the electrolyte. In this Comment, I argue that more emphasis should be placed on characterizing electrodics behaviour to facilitate both conceptual understanding and advancements in e…
