“…5,[35][36][37][38] As demonstrated by Zhou et al 39 large and ordered pore arrays are very beneficial to the intercalation of lithium, which is known as a slow bulk-phase reaction. The hierarchical structure of our Fe/Fe 3 O 4 /N-carbon composite is readily accessed by the electrolyte solution, that is Li + ions can freely move into large pores and intercalate into the thin pore walls and the N-loading location.…”

2015). A Fe/Fe3O4/N-carbon composite with hierarchical porous structure and in situ formed N-doped graphene-like layers for high-performance lithium ion batteries. Dalton Transactions: an international journal of inorganic chemistry, 44 (10), 4594-4600. A Fe/Fe3O4/N-carbon composite with hierarchical porous structure and in situ formed N-doped graphene-like layers for high-performance lithium ion batteries AbstractFe/Fe3O4/N-carbon composite consisting of a porous carbon matrix containing a highly conductive Ndoped graphene-like network and Fe/Fe3O4 nanoparticles was prepared. The porous carbon has a hierarchical structure which is inherited from rice husk and the N-doped graphene-like network formed in situ. When used as an anode material for lithium batteries, the composite delivered a reversible capacity of approximately 610 mA h g(-1) at a current density of 200 mA g(-1) even after 100 cycles, due to the synergism between the unique hierarchical porous structures, highly electrically conductive N-doped graphene-like networks and nanosized particles of Fe/Fe3O4. This work provides a simple approach to prepare N-doped porous carbon activated nanoparticle composites which could be used to improve the electrochemical performance of lithium ion batteries. hierarchical structure which is inherited from rice husk and the N-doped graphene-like network formed in situ.

“…Due to a number of materials being investigated as anode in LIBs (Cherian et al 2013a;Jibin et al 2012), there are lots of possibilities (Roy and Srivastava 2015). Presently, graphite (theoretical capacity *372 mAh/g) is the commonly used anode material in commercial LIBs due to its good cyclability (van Schalkwijk and Scrosati 2007;Wu et al 2003). However, poor intercalating rate capabilities and low specific capacity of graphite anode restrict its usefulness in high energy applications (Sivakkumar et al 2010).…”

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.

Epoxy resin composites reinforced to different types of carbon nano-particles have been fabricated. Carbon black (20, 30 and 40 wt. %), graphene (0.5 to 4 wt. %) and carbon nanotubes (CNT) (0.5 to 2 wt. %) were added with different weight percentages to epoxy. The dielectric strength of composites was tested in several conditions such as (dry, wet, low salinity and high salinity). The mechanical characterization showed that the nano-composite Polymer enhanced by using these particles in the tensile strength. Thermal gravimetric analysis shows effect of these nano-particles on the thermal structure of epoxy resin. Scanning Electron Microscopic test is used to characterize the dispersion of carbon nano-particles and to analysis the fractured parts in the nano scale.

Kamel, Maintenance Engineer at Marwa Company, Aswan, Egypt. Email: eng.marina2013@gmail.com INTRODUCTIONThe electrical behavior for epoxy hybrid composites depends on the added filler. Therefore the filler contains two types with different particle size (filler). The main purpose of filler addition is the improvement of electrical performance and mechanical feature. The resistivity of composite with filler is maximized comparing with nano and micro composite [1]. Conducting polymers have been the subjects of study for many decades as possible synthetic metals. However, the practical uses of conducting polymers are not very likely because of their poor mechanical properties and process ability that rarely meet the industrial requirements. Thus, a unique combination of electronic and mechanical properties of composites of conducting polymers with conventional polymers seems to have great applications. The applications of conducting polymers are used in light emitting diode (LED) [2], sensors [3], a microbial fuel cell (MFC) [4], Organic Thin Film Transistor (OTFT) [5]. The field of nanoscience has blossomed over the last two decades and the importance of nanotechnology increase in areas such as computing, sensors, biomedical and many other applications. In this regard the discovery of grapheme [6] and graphene-based polymer nano composites is an important addition in the field of nano science. Carbon nanotubes were first discovered in 1991, and quickly became the focus of much research activity, due to their exceptional electrical, mechanical, and thermal properties [7].Carbon assumes an array of structural forms, such as diamond, graphite, graphene, fullerenes, carbon nanotubes, and amorphous carbon [8], [9]. Carbon nanomaterials have emerged as a rising star in the material science community, during the past two decades [10][11][12]. Carbon nanotubes and graphenes are also studied for the development of batteries, supercapacitors, and fuel cells [13][14][15][16][17][18][19][20]. Most of the research works on the conductive polymers composites focus on modi...
