| Zusammenfassung: | The present invention relates to a negative electrode material for secondary batteries. Specifically, the negative electrode material for secondary batteries, according to the present invention, comprises: silicon nanoparticles; a first conductive carbon body having a two-dimensional nanostructure; a second conductive carbon body having a one-dimensional nanostructure; and a conductive carbon-based binder. The silicon nanoparticles and the first conductive carbon body are aggregates bonded by the conductive carbon-based binder, and the second conductive carbon body is bonded to the aggregates to connect the aggregates.
