LiFePO4 (space group: Pnma) was synthesized by the hydrothermal method at 443 K. The pH of precursor solution systematically changed between 2.5 and 9.5. particle morphology, crystal orientation, electrochemical reactivity prepared particles depending on concentration Li source precursor. obtained from acidic solutions (pH ≈ 3.5) were needle-like particles. On other hand, plate-like crystals weak 4 < 6.5. At higher than 7.2, became randomly shaped. had a large facet in ac-plane, while...
Three dimensionally ordered macroporous (3DOM) carbons with mesoporous walls were prepared by a colloidal crystal templating method. A three composite consisting of monodisperse polystyrene (PS) latex (100–450 nm) and silica (5–50 was an evaporation process suspensions containing PS in water. In the course heat treatment this membrane at 573 K under inert atmosphere, melted penetrated into spaces between silica. The carbonized during further to provide very thin carbon layer on silica,...
A star-shaped copolymer, poly(styrene)-block-poly[poly(ethylene glycol) methyl ethyl methacrylate , was synthesized by the combination of living anionic polymerization styrene and ruthenium-catalyzed radical poly(ethylene ether methacrylate. The prepared copolymer characterized to evaluate its use as a solid polymer electrolyte (SPE) in lithium-ion batteries. star comprised hard, condensed poly(styrene) part at center, which enhanced mechanical properties solid-state polymer, soft, mobile...
Fluoride ion batteries (FIBs) are regarded as promising energy storage devices, and it is important urgent to develop cathode materials with high densities for use in FIBs.
With the increasing development of electric vehicles and portable devices, there is a strong requirement for high-energy batteries. To improve battery energy, multielectron transfer electrode reactions can be applied. Previously, batteries based on fluoride-ion shuttle (F– ion batteries, FiBs) have been reported, utilizing electrodes with reactions. Although these FiBs exhibit high theoretical energy densities, reported capacities are significantly less than values. Moreover,...
Metallic Li deposited on the anode is known to induce short circuiting and degradation of charge capacity Li-ion batteries. However, no reliable technique currently available observe such metal without removing case battery. An elemental analysis using muonic X-rays proposed here because its unique properties nondestructive measurement, high sensitivity light elements, depth resolution. We demonstrated that this can be applied detection surface an containing ions, a fully charged with due...
