A carbon/nanoparticle nanofiber includes a carbon base structure and a plurality of nanoparticles that include a lithium alloy or a lithium alloy precursor. One or more nanofibers may be formed into a nonwoven fabric. The fabric may be utilized as an electrode, such for example in a battery. The carbon/nanoparticle composite nanofiber may be fabricated by forming a polymer/nanoparticle nanofiber, such as for example by a spinning technique, and carbonizing the polymer/nanoparticle nanofiber. L'invention concerne une nanofibre carbone/nanoparticule qui comporte une structure de base de carbone et une pluralité de nanoparticules qui comporte un lithium allié ou un précurseur en lithium allié. Une ou plusieurs nanofibres peuvent être formées en tissu non tissé. Le tissu peut être utilisé comme électrode, comme dans une batterie. La nanofibre composite carbone/nanoparticules peut être fabriquée par formation d'une nanofibre polymère/nanoparticules, comme par une technique de filage, puis par carbonisage de la nanofibre polymère/nanoparticules.
