Highly flexible vanadium and nitrogen co-doped carbon films were synthesized by electrospinning, delivering an outstanding discharge capacitance of 1380 mA h g−1 at 0.1 A g−1. The Coulombic efficiency was as high as 63.3% and a capacity retention ratio of 80% was obtained after cycling at 6.4 A g−1 for 500 times.

Limiting Surface

Core–shell Si/Cu nanocomposites were synthesized via a flexible self-limiting surface reaction without extra reductant for the first time. The nano Si was uniformly coated with Cu nanoparticles with a diameter of 5–10[Formula: see text]nm, which can enhance the electronic conductivity of the nanocomposites and buffer the huge volume change during charge/discharge owing to its high ductility. Benefited from the unique structure, the Si/Cu nanocomposites exhibited a good electrochemical performance as anodes for lithium ion batteries, which exhibited a capacity retention of 656[Formula: see text]mAh/g after 50 cycles and a coulombic efficiency of more than 99%.
