Synthesis of Microspherical LiFePO4-Carbon Composites for Lithium-Ion Batteries

Synthesis of Microspherical LiFePO4-Carbon Composites for Lithium-Ion Batteries

This paper reports an “all in one” procedure to produce mesoporous, micro-spherical LiFePO4 composed of agglomerated crystalline nanoparticles. Each nanoparticle is individually coated with a thin glucose-derived carbon layer. The main advantage of the as-synthesized materials is their good performa...
