Deskripsi
Understanding the solid–electrolyte interphase (SEI) is key to developing safe dendrite-free lithium batteries. Here, by exploiting the electrons in lithium metal to selectively hyperpolarise the NMR signals, the authors reveal the chemistry and spatial distribution of species at the metal–SEI interface.
