Sol–gel synthesis of nanostructure LiFeBO3/C lithium-ion cathode materials with high storage capacity

Brief Communication: Industrial and technological applications of sol-gel and hybrid materials


Nanostructure LiFeBO3/C composite is synthesized by sol–gel method using CH3COOLi·2H2O, Fe(NO3)3·9H2O, H3BO3 and citric acid as starting materials. The crystal structure, morphology and electrochemical properties of LiFeBO3/C composites are characterized by X-ray diffraction, transmission electron microscopy, raman spectroscopy (Raman), cyclic voltammetry, electrochemical impedance spectroscopy and charge–discharge tests. The LiFeBO3/C is comprised of individual near spherical particles of the size range 40–60 nm, and well coated by thin carbon layer. The LiFeBO3/C can deliver an initial discharge capacity of 205.8 mAh g−1 under the current density of 10 mA g−1 in the potential range 1.8–4.5 V, and it can deliver the capacity of 159.3 mAh g−1 after 20 cycles. When the current density is increased to 20 and 40 mA g−1, the capacity of LiFeBO3/C could also be retained at 120.6 and 102.6 mAh g−1. The excellent cycling performance indicates, the materials have good application prospect.

Graphical Abstract

Open image in new window The morphology and size of the sol-gel synthetic LiFeBO3 materials are characterizedby TEM were shown in the Figure. It can illustrate that the LiFeBO3/C consists of individual near spherical particles of the size range 40∼60 nm. With further investigate by HR-TEM that LiFeBO3/C showed clear crystal lattice stripes and a uniform carbon film is coated on the particle surface.
