Abstract

original image

From the spinning room: LiFePO4 is a promising cathode material for lithium batteries, but it suffers from slow mass and charge transport. Electrospinning is able to produce single-crystalline LiFePO4 nanowires coated with amorphous carbon (see TEM images and small-angle electron diffraction pattern). Networks of these wires show very short diffusion lengths, thus leading to high rate performance and cycling capability.
