Cover Feature: Interconnected Two‐dimensional Arrays of Niobium Nitride Nanocrystals as Stable Lithium Host (Batteries & Supercaps 1/2021)

The Cover Feature illustrates 2D arrays of NbN nanocrystals, which are used as stable Li host. Coupled with lithium nickel–manganese–cobalt oxide, a long-term cycling full Li-metal battery is realized under practical condition. More information can be found in the Communication by Y. Gogotsi and co-workers.
