Electrospun Pitch/Polyacrylonitrile composite carbon nanofibers as high performance anodes for lithium-ion batteries
A new kind of soft carbon and hard carbon composite nanofibers were fabricated from isotropic pitch and polyacrylonitrile via simple electrospinning followed by stabilization and carbonization. The obtained fibrous mat was directly used as anodes of lithium-ion batteries without binder added and current collector. The composite nanofibers electrodes display a large reversible capa...

Composite of mesocarbon microbeads/hard carbon as anode material for lithium ion capacitor with high electrochemical performance.
Lithium-ion capacitor (LIC) is fabricated using activated carbon (AC) as the positive electrode and a mixture of mesocarbon microbeads (MCMB) and hardcarbon (HC) as the negative electrode (denoted as MH). The structure characterization of carbon materials are investigated by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and nitrogen adsorption apparatus. The electro...

Electrochemical Performance of Electrospun carbon nanofibers as free-standing and binder-free anodes for Sodium-Ion and Lithium-Ion Batteries
A series of hard carbon nanofiber-based electrodes derived from electrospun polyacrylonitrile (PAN) nanofibers (PAN-CNFs) have been fabricated by stabilization in air at about 280 degrees C and then carbonization in N-2 at heat treatment temperatures (HTT) between 800 and 1500 degrees C. The electrochemical performances of the binder-free, current collector-free carbon nanofiber-based anodes in li...

Effect of pre-lithiation degrees of mesocarbon microbeads anode on the electrochemical performance of lithium-ion capacitors
Lithium ion capacitors are assembled with pre-lithiated mesocarbon microbeads (LMCMB) anode and activated carbon (AC) cathode. The effect of pre-lithiation degrees on the crystal structure of MCMB electrode and the electrochemical capacitance behavior of LIC are investigated by X-ray diffraction (XRD) and the charge-discharge test of three-electrode cell. The structure of graphite still maintained...

Effect of the capacity design of activated carbon cathode on the electrochemical performance of lithium-ion capacitors.
Lithium-ion capacitors (LICs) are assembled with activated carbon (AC) cathode and pre-lithiated mesocarbon microbeads (MCMB) anode. The effect of AC cathode capacity design on the electrochemical performance of LIC is investigated by the galvanostatic charging-discharging and electrochemicalimpedance tests. As the designed capacity of AC positive electrode is lower than 50 mAhg(-1), the working p...

Facile fabrication of phosphorus-doped g-C3N4 exhibiting enhanced visible light photocatalytic degradation performance toward textile dye
Phosphorus-doped graphitic carbon nitride (P-g-C3N4) was facilely fabricated by in situ thermal copolymerization of urea and triphenylphosphine source materials. The P-g-C3N4 exhibited an enhanced photocatalytic performance than pristine g-C3N4 counterpart for the degradation of rhodamine B and acid blue D-2BR textile dye under visible light irradiation. X-ray diffraction (XRD), transmission elect...

【Nanoscale Research Letters】Temperature-dependent gas transport performance of vertically aligned carbon nanotube/parylene composite membranes
A novel composite membrane consisting of vertically aligned carbon nanotubes (CNTs) and parylene was successfully fabricated. Seamless filling of the spaces in CNT forests with parylene was achieved by a low-pressure chemical vapor deposition (CVD) technique and followed with the Ar/O2 plasma etching to expose CNT tips. Transport properties of various gases through the CNT/parylene membranes wer...

Robust and flexible cellulose nanofiber/multi-walled carbon nanotube film for high-performance electromagnetic interference shielding
For the preparation of lightweight and high performance electromagnetic interference shielding material, the poor dispersion of carbon nanotube (CNT) and the weak interfacial strength degrade the mechanical properties of the polymer based composite with extremely high filler contents. Herein cellulose nanofibers (CNF) prepared by TEMPO-oxidized exhibits a&...
