Conventional graphitic anodes in lithium-ion batteries cannot provide high-power densities due to slow diffusivity of lithium ions the bulk electrode material. Here we report photoflash and laser-reduced free-standing graphene paper as high-rate capable for batteries. Photothermal reduction oxide yields an expanded structure with micrometer-scale pores, cracks, intersheet voids. This open-pore enables access underlying sheets facilitates efficient intercalation kinetics even at ultrafast...
In this study, we report a novel route via microwave irradiation to synthesize bio-inspired hierarchical graphene–nanotube–iron three-dimensional nanostructure as an anode material in lithium-ion batteries. The comprises vertically aligned carbon nanotubes grown directly on graphene sheets along with shorter branches of stemming out from both the and nanotubes. This structure provides conductive network for efficient charge-transfer prevents agglomeration restacking enabling Li-ions have...
Silicon (Si) shows promise as an anode material in lithium-ion batteries due to its very high specific capacity. However, Si is highly brittle, and effort prevent from fracturing, the research community has migrated use of films nanoparticle based electrodes. such a strategy significantly reduces volumetric energy density porosity Here we show that contrary conventional wisdom, can be stabilized by two strategies: (a) anchoring carbon nanotube macrofilm (CNM) current collector (b) draping...
Abstract Prevention of microbially induced corrosion (MIC) is great significance in many environmental applications. Here, we report the use an ultra-thin, graphene skin (Gr) as a superior anti-MIC coating over two commercial polymeric coatings, Parylene-C (PA) and Polyurethane (PU). We find that Nickel (Ni) dissolution cell with Gr-coated Ni order magnitude lower than PA PU coated electrodes. Electrochemical analysis reveals Gr offers ~10 ~100 fold improvement MIC resistance coatings...
Previous studies of the interaction water with graphene-coated surfaces have been limited to flat (smooth) surfaces. Here we created a rough surface by nanopatterning and then draped single-layer graphene sheet. We found that ultrasheer drape prevents penetration into textured thereby drastically reducing contact angle hysteresis (which is measure frictional energy dissipation) preventing liquid line from getting pinned substrate. This has important technological implications since main...
