摘要: 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 the as-synthesized materials their good performance at high charge-discharge rates. nanoparticles and mesoporosity guarantee short bulk diffusion distance for both lithium ions electrons, as well additional active sites charge transfer reactions. At same time, interconnected coating provides conductive framework capable delivering electrons nanostructured LiFePO4.
