The Li3V2(PO4)3/reduced graphene oxide (LVP/rGO) composite is successfully synthesized by a conventional solid-state reaction with a high yield of 10 g, which is suitable for large-scale production. Its structure and physicochemical properties are investigated using X-ray diffraction, Raman...
LiFePO4/C composites were synthesized by carbothermal reduction method using commercial FePO4 and Tween#80-assisted synthesized nano-FePO4 as starting materials, glucose as reducing agent, and also carbon source. The FePO4 intermediates were characterized by X-ray diffraction and scanning...
Li1.3Al0.3Ti1.7(PO4)3 films were comparatively prepared by rapid thermal annealing (RTA) and conventional furnace annealing(CFA). The phase identification and surface morphology of the prepared films were characterized by X-ray diffraction and scanning electron microscopy. The electrochemical...
In this paper, we reported a one-pot method to synthesize MnO/C hybrid microspheres via solvothermal approach for the first time. Only peaks of MnO could be observed from X-ray diffractometry patterns, indicating that the carbon in the composite was amorphous. Scanning electron microscope and...
Lithium salt, LiX (where X = BF
, I−, CF3SO
), was incorporated into epoxidized natural rubber (ENR). Thin films of LiX-ENR polymer electrolytes (PEs) were obtained via solvent casting method. These electrolytes were characterized using SEM/X-mapping, FTIR,...
Polycarbonates (4a–d) with various side chain lengths were synthesized by the reaction of 1,4-bis(hydroxyethoxy)benzene derivatives and triphosgene in the presence of pyridine. The polymer electrolytes composed of 4a–d with lithium bis(trifluoromethanesulfonyl)imide (LiN(SO2CF3)2, LiTFSI) were...
The proton activity of the Nafion membrane was estimated from the potential difference between a normal hydrogen electrode (NHE) in 0.5 mol dm−3 H2SO4 and a dynamic hydrogen electrode (DHE) constructed on a Nafion 117 membrane. The potential difference between the DHE and the NHE was directly...
Poly(vinylidene fluoride-co-hexafluoropropene)–hexafluoropropylene (PVdF-HFP; M
n, 130,000)-based membranes were prepared by means of phase inversion technique by coagulating with water and MeOH and then doping with H3PO4 and H2SO4. In order to improve the electrochemical properties of the...
The composite solid electrolytes, NaSn2F5, dispersed with submicron size Al2O3 fillers of various concentrations and particle sizes have been synthesized through mechanochemical milling technique. X-ray diffraction and microstructure results indicate the biphasic nature of the composite...
Nickel hydroxide mesoporous structures are synthesized by a simple method in the presence of different additives (oxalic acid, aminoacetic acid, and sulfosalicylic acid). Structural characterizations reveal that the additives can affect the crystal structure, increase the specific surface area,...
