An improved Hummers method was used to the preparation of exfoliated graphite oxide(GO), and graphene with high-surface area was obtained after chemical reduction of GO by hydrazine hydrate.A stable s
Graphene has attracted intense interest because of its superb properties, such as high mobility and optical transparency.Meanwhile, depositing graphene on appropriate substrates is one of the main obs
Supercapacitors have sparked enormous interest in the field of electrical energy storage devices due to their high power density, long cycle life, wide operating temperature range, and short charging
Synthesis and electrochemical properties of graphene-modified LiCo1/3Ni1/3Mn1/3O2 cathodes for lithi
Previous investigations indicate that graphene can be used to effectively improve the electrochemical performance of LiFePO4 cathodes.LiCo1/3Ni1/3Mn1/3O2 (LCMNO) is a much more attractive cathode, and
Strong chemical interactions between the oxygen-containing functional groups on graphene oxide (GO) sheets and divalent metals ions were exploited for the softening of hard water.GO membranes were pre
Li4Ti5O12 with good crystallization and nanometer-size (18 nm) was in-situ grown on monolayer graphene (2 nm) using OmimCl as exfoliated agent.Such Li4Ti5O12/graphene nanostructure exhibits excellent
Reduced graphene oxide/ordered mesoporous carbon nanospheres composites used as supercapacitor elect
Graphene based carbon materials are promising electrodes for supercapacitors due to the high surface area, great conductivity of graphene, and remarkable chemical stability of the composites.In this p
P-phenylenediamine (PPD) functionalized graphene oxide (GO) materials (PPDG) were prepared through a one-step solvothermal process and their application as supercapacitors were studied.The structures
LiMnPO4/C materials were prepared by solid state reaction method by using traditional raw materials,surfactant-assisted precipitated NH4MnPO4·H2O as reactants respectively,and the structural and elect
