In Situ Grown Hierarchical Electrospun Nanofiber Skeletons with Embedded Vanadium Nitride Nanograins for Ultra‐Fast and Super‐Long Cycle Life Aqueous Zn‐Ion Batteries (Adv. Energy Mater. 5/2023)

Abstract

Aqueous Zinc‐Ion Batteries In article number 2202826, Lingna Sun, Hui Ying Yang and co‐workers produce 3D self‐supported VN‐embedded N‐doped carbon nanofiber (VN/N‐CNFs) composites with hierarchical structures by an electrospinning technique and introduction of vanadium‐based metal organic frameworks, yielding a homogeneous distribution of 0D active VN nanograins into electrospun nanofiber‐knitted carbon skeletons. This design strategy leads to an ultra‐long cycle lifespan and super‐high rate capability with high capacities and energy/power densities for aqueous zinc‐ion batteries.
