Lithium-ion batteries have witnessed meteoric advancement the last two decades. The anode area has seen unprecedented research activity on Si and Sn, alternatives to currently used carbon following initial seminal work by Fuji tin oxide nanocomposites. Recent reports silicon nanowires, porous Si, amorphous coatings graphite nanofibers (GNF) been very encouraging. High capacity long cycle life anodes are still, however, elusive much needed meet ever increasing energy storage demands of modern...
The properties of amorphous 250 nm and 1 μm silicon films deposited by radio-frequency (rf) magnetron sputtering on copper foil are investigated using -ray diffraction, scanning electron microscopy (SEM), electrochemical methods. Galvanostatic half-cell measurements conducted between 0.02 1.2 V a lithium counter electrode have shown that the Si thin exhibit an excellent reversible specific capacity nearly 3500 mAh/g when tested for 30 cycles. high cyclability sputtered suggest adhesion Cu...
Rechargeable lithium ion batteries are integral to today's information-rich, mobile society. Currently they one of the most popular types battery used in portable electronics because their high energy density and flexible design. Despite increasing use at present time, there is great continued commercial interest developing new improved electrode materials for that would lead dramatically higher capacity longer cycle life. Silicon promising anode it has highest known theoretical charge...
Blends of biodegradable polymers, poly(caprolactone) and poly(D, L-lactic-co-glycolic acid), have been examined as scaffolds for applications in bone tissue engineering. Hydroxyapatite granules incorporated into the blends porous discs were prepared. Mechanical properties degradation rates vitro composites determined. The seeded with rabbit marrow or cultured stromal cells incubated under physiological conditions. Polymer/ceramic supported cell growth throughout scaffold 8 weeks. Scanning...
Amorphous silicon thin films deposited on copper foil have been observed to exhibit near theoretical capacity for a limited number of cycles. The films, however, eventually delaminate, leading failure the anode. In order better understand mechanism retention and ultimate mode model brittle active:elastic/plastic inactive anode system, were subjected in situ adhesion tests while observing film surface using scanning electron microscopy. Atomic force transmission microscopy, electrochemical...
Titanium nitride (TiN) nanocrystallites exhibiting high specific surface area (∼128 m 2 /g) for electrochemical capacitor application were obtained by a two-step halide approach comprised of room-temperature TiCl 4 (1)-NH 3 (g) reaction followed heat-treatment under NH atmosphere. The synthesized powders agglomerates containing spherical crystallites ∼ 10 nm in diam and exhibit ranging from 128 to 23 /g depending on the temperature. capacitance evaluated cyclic voltammetry 1 M KOH...
Abstract Identification of low cost, highly active, durable completely noble metal-free electro-catalyst for oxygen reduction reaction (ORR) in proton exchange membrane (PEM) fuel cells, evolution (OER) PEM based water electrolysis and metal air batteries remains one the major unfulfilled scientific technological challenges acid mediated electro-catalysts. In contrast, several non-noble metals electro-catalysts have been identified alkaline neutral medium cells. Herein we report very first...
