A novel assembly of LiFePO4 microspheres from nanoplates

Author affiliations

Abstract

In this work, LiFePO4 microspheres with an enhanced tap density were assembled from nanoplates via solvothermal treatment with TiN nanoparticles as a conductive connector. By altering the amount of introduced TiN nanoparticles, the morphology of the as-prepared LiFePO4 can be tailored. It is demonstrated that TiN nanoparticles favor crystal growth along the b axis by breaking the surfactant blocking barrier, which has a significant effect upon the assembly of LiFePO4 nanoplates. Enhanced electronic and ionic conductivity of a LiFePO4 electrode is confirmed by electrochemical impedance spectroscopy and linear voltage scanning methods, which are beneficial to the battery performance.
