1. A process for preparing a silicon-carbon nanocomposite nanofiber, the process comprising:

  • a. providing an aqueous fluid stock comprising polyvinylalcohol, a plurality of silicon nanoparticles having an average diameter of less than 100 nm, and a nanostructured carbon having an aspect ratio of at least 5, the weight-to-weight ratio of silicon nanoparticles to polyvinylalcohol being at least 1;

    10, and the weight-to-weight ratio of nanostructured carbon to polyvinylalcohol being at least 1;

    10;

    b. electrospinning the fluid stock, producing a nanofiber comprising the polyvinylalcohol, the silicon nanoparticles, and the nanostructured carbon, the electrospinning being gas assisted; and

    c. thermally carbonizing the polyvinylalcohol of the nanofiber, thereby producing the silicon-carbon nanocomposite nanofiber,the silicon-carbon nanocomposite nanofiber comprising at least 60 elemental wt. % silicon and 5 wt. % to 25 wt. % carbon.
