“…However, poor intercalating rate capabilities and low specific capacity of graphite anode restrict its usefulness in high energy applications (Sivakkumar et al 2010). Therefore, exhaustive research efforts are being carried out to identify a better electrode system such as alloying electrodes (Si, Sn, V etc.,) and nanometric transition metal oxides (Cheng et al 2016;Goriparti et al 2014).…”

Tin oxide-carbon composite porous nanofibres exhibiting superior electrochemical performance as lithium ion battery (LIB) anode have been prepared using electrospinning technique. Surface morphology and structural characterizations of the composite material is carried out by techniques such as XRD, FESEM, HR-TEM, XPS, TGA and Raman spectroscopy. FESEM and TEM studies reveal that nanofibers have a uniform diameter of 150-180 nm and contain highly porous outer wall. The carbon content is limited to *10% in the nanofibers as shown by the TGA and EDAX which does not fade the high capacity of SnO 2 . These nanofibers delivered a higher discharge capacity of 722 mAh/g even after 100 cycles at high rate of 1C. The excellent electrochemical performance can be ascribed to the synergy effect of small amount of carbon in the composite and the hierarchically porous structure which accommodate large volume changes associated with Li-ion insertion-desertion. The porous nano-architecture would also provide a short diffusion path for Li ? ions in addition to facilitating high flux of electrolyte percolation through micropores. The electrochemical performance of composite material has also been tested at 60°C at a higher rate of 2C and 5C. Post cycling FESEM analysis shows no volumetric and morphology changes in porous nanofibers after completing rate capability at high rate of 10C.

Abstract.A simply and cheap solid state synthesis was used to produce powders of spinel phase Li4-xCuxTi5O12, where 0≤x≤0.2, with crystallite size in ~890 nanometers range. The as-prepared samples were verified by scanning electron microscopy and X-ray diffraction. The electrochemical performance of these samples was examined by galvanostatic and voltamperometric tests. To determine transport properties an impedance spectroscopy tests were obtained. These measurements showed excellent high-rate performance and remark-ably good cyclability of the fabricated powders. Capacity retention in Li3.85Cu0.15Ti5O12 has 77% theoretical capacity after raise the discharge current from 1C to 10C and there is less than 2% of capacity loss after 50 charge/discharge cycles at 1C current rate.

“…Carbon materials, including activated carbons, carbon aerogels, carbon nanofibers (CNFs), and graphene materials, have been extensively investigated for efficient and long-lasting energy storage in EDLCs and LiBs [3][4][5][6][7]. In an EDLC, electrical energy is stored by the electrostatic accumulation of charge in the electric double-layer at the electrode/electrolyte interface, thus making it possible to achieve fast charge-discharge rates and high power values.…”

Herringbone, platelet, and tubular carbon nanofibers (CNFs) were synthesized by catalytic chemical vapor deposition using methane, propane, and ethylene as carbon precursors. Alumina-supported nickel and iron catalysts were used for the syntheses. The resultant CNFs were characterized by scanning electron microscopy, transmission electron microscopy, and nitrogen sorption at 77 K. The performance of a CNF-based supercapacitor working in 6 mol L -1 KOH was analyzed using cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy techniques. The Brunauer-Emmett-Teller (BET) surface area of the CNFs ranged between 150 and 296 m 2 g -1 . An increase in the CNF diameter was accompanied by a decrease in the BET surface area. A comparison of the porous textures and the structure types of the CNFs demonstrated that the performance of the CNF-based supercapacitor is enhanced primarily by the exposed edges of the graphitic layers on the CNF surface, followed by the specific surface area. Among the studied CNFs, the highest capacitance value, 26 F g -1 at 0.2 A g -1 , was obtained for the platelet-type CNFs.Tubular CNFs exhibited the lowest capacitance value, which increased from 4 to 33 F g -1 at 0.2 A g -1 upon air treatment at 450°C. The presence of exposed graphitic edges on the air-treated CNT surface and an increase in the specific surface area are considered to be responsible for the enhancement of the capacitor performance.
