Bundled nanofibers of V-doped LiMn2O4 spinel

A new bunching of nanomaterials is reported, as nanofibers (ca. 10–50 nm in diameter) which form huge skeins of ca. 20–50 μm. LiMn2O4, as a promising candidate for lithium batteries which needs improvement of solid-state diffusion, was synthesized with this nanostructure. The process was simply a hydrothermal synthesis of LiMn2O4 while a small amount of vanadium is incorporated into the spinel lattice. This work reports a novel bunching phenomenon in the realm of solid-state physics and nanotechnology.
