Na‐Ion Batteries: A Confined Replacement Synthesis of Bismuth Nanodots in MOF Derived Carbon Arrays as Binder‐Free Anodes for Sodium‐Ion Batteries (Adv. Sci. 16/2019)

In article 1900162, Yaping Wang, Anqiang Pan, Shuquan Liang, and co‐workers embed bismuth nanodots in metal–organic framework–derived carbon arrays on carbon fibers through a confined replacement reaction. As binder‐free anode for sodium‐ion batteries, nanosized bismuth and plenty phase boundaries enable fast sodium storage kinetics. [Image: see text]
