Synthesis of Fe(2+) Substituted High-Performance LiMn(1−x)Fe(x)PO(4)/C (x = 0, 0.1, 0.2, 0.3, 0.4) Cathode Materials for Lithium-Ion Batteries via Sol-Gel Processes

A series of carbon-coated LiMn(1−x)Fe(x)PO(4) (x = 0, 0.1, 0.2, 0.3, 0.4) materials are successfully constructed using glucose as carbon sources via sol-gel processes. The morphology of the synthesized material particles are more regular and particle sizes are more homogeneous. The carbon-coated LiM...

description A series of carbon-coated LiMn(1−x)Fe(x)PO(4) (x = 0, 0.1, 0.2, 0.3, 0.4) materials are successfully constructed using glucose as carbon sources via sol-gel processes. The morphology of the synthesized material particles are more regular and particle sizes are more homogeneous. The carbon-coated LiMn(0.8)Fe(0.2)PO(4) material obtains the discharge specific capacity of 152.5 mAh·g(−1) at 0.1 C rate and its discharge specific capacity reaches 95.7 mAh·g(−1) at 5 C rate. Iron doping offers a viable way to improve the electronic conductivity and lattice defects of materials, as well as improving transmission kinetics, thereby improving the rate performance and cycle performance of materials, which is an effective method to promote the electrical properties.
