Improving electrochemical properties of hydrothermally synthesized LiFePO(4) powders is immense technological significance and has been a subject much scientific inquiry for many years. As reported previously, reversing the feeding sequence starting materials and/or introducing ethylene glycol (EG) could significantly improve performance LiFePO(4). However, mechanism remains unclear. Here, we report systematic study to understand from viewpoints crystal growth defect concentration control....
The low-temperature hydrothermal synthesis method has been drawing ever-growing attention due to the fact that it many advantages over conventional methods for preparing promising cathode material LiFePO4. However, mechanism of LiFePO4 remains unclear. Here, reaction is systematically studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared spectroscopy (FTIR), and specific surface analysis. As evidenced apparent precursor...
AbstractIn this paper, fullerenes (C60)/graphene composite was synthesized to report. The C60/graphene constructed first with graphene oxide and Li-functionalized C60 particles by a facile solution method. samples were characterized Raman spectroscopy, X-ray diffraction, transmission electron microscopy, Fourier transform infrared measurements, photoelectron spectroscopy analysis. It revealed that the attached onto surface of graphene. prepared employed as electrode in supercapacitors. found...

Due to the large volume fraction of electrochemically inactive materials involved in conventional thin calendered electrodes, it is challenging approach high volumetric capacity. Here, we report a proof-of-concept study on LiFePO4-based bulk as opposed electrodes. The electrodes are hierarchically porous, electro-conductive, metal current collector- and polymeric binder-free. In combination with 3D pore topologies electronic conduction, even small quantity conductive agents (5.6 wt%),...
Preparing an excellent catalyst, a Ag–MnO<sub>2</sub>/graphene composite, for the oxygen reduction reaction through facile method.
Abstract TiNb 2 O 7 (TNO) is a promising anode material for lithium‐ion batteries because of its high capacity and long cyclic life. Nevertheless, practical application limited by sluggish ionic electronic conductivity. Alien ion doping one the most simple effective methods to optimize electrochemical performance materials. Herein, H MoO 4 derived Mo‐doped (Mo‐TNO) microspheres have been synthesized via solvothermal method followed calcining process. The resulting Mo‐TNO displays an...
