Electrochemical performance of nano-sized LiFePO-embedded 3D-cubic ordered mesoporous carbon and nitrogenous carbon composites.

Herein, we report a single-step synthesis, characterization, and electrochemical performance of nano-sized LiFePO (LFP)-embedded 3D-cubic mesoporous carbon (CSI-809) and nitrogenous carbon (MNC-859) composites. Furthermore, in order to investigate the effects of both CSI-809 and MNC-859 on the electrochemical characteristics of LFP, a systematic study was performed on the morphology and microstructure of the composites, , LFP/CSI-809 and LFP/MNC-859, using XRD, FE-SEM, FT-Raman, and BET surface area analyses. Among these composites, LFP/MNC-859 exhibited better electrochemical performance with higher specific capacity and rate capability as compared to those of LFP/CSI-809.

Surfactant-Mediated and Morphology-Controlled Nanostructured LiFePO/Carbon Composite as a Promising Cathode Material for Li-Ion Batteries.

The synthesis of morphology-controlled carbon-coated nanostructured LiFePO (LFP/Carbon) cathode materials by surfactant-assisted hydrothermal method using block copolymers is reported. The resulting nanocrystalline high surface area materials were coated with carbon and designated as LFP/C123 and LFP/C311. All the materials were systematically characterized by various analytical, spectroscopic and imaging techniques.
