摘要：

A novel solvothermal approach combined with high-temperature calcinations was developed to synthesize on a large scale LiFePO4 microspheres consisting of nanoplates or nanoparticles with an open three-dimensional (3D) porous microstructure. These micro/nanostructured LiFePO4 microspheres have a high tap density and, as electrodes, show excellent rate capability and cycle stability.
