Abstract

The nanostructured Li(Ni1/3Co1/3Mn1/3)O2/Li(Ni1/2Mn1/2)O2 fibers for use as lithium ion batteries were prepared by co-electrospinning combined with a sol–gel method. The core–shell Li(Ni1/3Co1/3Mn1/3)O2/Li(Ni1/2Mn1/2)O2 fibers show diameter of less than 5 μm and shell thickness of ca.300 nm, which are composed of the randomly arranged nanoparticles with size of 20–50 nm. The charge–discharge curves and cycle performance analyses indicated that the core–shell Li(Ni1/3Co1/3Mn1/3)O2/Li(Ni1/2Mn1/2)O2 fibers possess a high charge–discharge capacity, as well as good cyclical stability.
