COVER

摘要

<正>The cover image presents the introduction of tin(Sn) to optimize the component and structure of two-dimensional(2D) of nitrogen(N)-doped carbon(C) fibers as free-standing anodes for high-performance Li-ion batteries. In article No. 2305007, Yi and Chen et al. demonstrate an electrospinning strategy to synthesize cross-linked N-doped C-Sn nanofibers for investigating the lithium storage mechanism and the reason for improving the electrochemical performance.
