Project: Construction of High Performance Amorphous FePO4-C Nanocomposites as Battery Cathode




1.Introduce hybrid carbon additives into the amorphous FePO4 cathodeas a hierarchical 3D conductive network.

The composites of a FePO4,carbon black, and carbon nanotubes exhibited distinct advantages of low costand excellent rate capacity over the composites of α-FePO4 and CNT, indicating the importance of optimizing the hierarchical structure of cathode composites.

Nanostructured a FePO4 CNT composites were directly synthesized by a fast precipitation technique in amembrane dispersion microreactor, which performed very well in terms ofspecific capacity and capacity retention. Furthermore, the approach is flexibleto control the ratio of FePO4 tocarbon and ensure the high purity of FePO4 without additional reagents requirement.
