Spray-Drying Synthesis of LiFeBO(3)/C Hollow Spheres With Improved Electrochemical and Storage Performances for Li-Ion Batteries

LiFeBO(3)/C cathode material with hollow sphere architecture is successfully synthesized by a spray-drying method. SEM and TEM results demonstrate that the micro-sized LiFeBO(3)/C hollow spheres consist of LiFeBO(3)@C particles and the average size of LiFeBO(3)@C particles is around 50–100 nm. The t...

description LiFeBO(3)/C cathode material with hollow sphere architecture is successfully synthesized by a spray-drying method. SEM and TEM results demonstrate that the micro-sized LiFeBO(3)/C hollow spheres consist of LiFeBO(3)@C particles and the average size of LiFeBO(3)@C particles is around 50–100 nm. The thickness of the amorphous carbon layer which is coated on the surface of LiFeBO(3) nanoparticles is about 2.5 nm. LiFeBO(3)@C particles are connected by carbon layers and formed conductive network in the LiFeBO(3)/C hollow spheres, leading to improved electrical conductivity. Meanwhile, the hollow structure boosts the Li(+) diffusion and the carbon layers of LiFeBO(3)@C particles protect LiFeBO(3) from moisture corrosion. Consequently, synthesized LiFeBO(3)/C sample exhibits good electrochemical properties and storage performance.
