Introducing microwave heating during sonication of graphite dispersions in aqueous solutions of NaCMC results in the formation of graphene dispersions with concentration as high as 4.29 mg/ml. It is found that drying the dispersions results in the formation of graphene/NaCMC composites with graphene content up to 38.65 wt%. A study of the composite with High Resolution Transmission Electron Microscopy and Raman Spectroscopy reveals the formation of few-layer graphene approximately below five layers. The as-prepared graphene/NaCMC composite shows higher capacities than commercial graphite in Li-ion half cells reaching 397 mAh/g (graphene) . Also, when the composite is used with a nanosilicon (33 wt%) in a Li-ion half cell high initial reversible capacities of 1611 mAh/g (Si) with good cyclability and rate capability have been reached.

A hybrid nano-urchin structure consisting of spherical onion-like carbon and MnO2 nanosheets is synthesized by a facile and environmentally-friendly hydrothermal method. Lithium-ion batteries incorporating the hybrid nano-urchin anode exhibit reversible lithium storage with superior specific capacity, enhanced rate capability, stable cycling performance, and nearly 100% Coulombic efficiency. These results demonstrate the effectiveness of designing hybrid nano-architectures with uniform and isotropic structure, high loading of electrochemically-active materials, and good conductivity for the dramatic improvement of lithium storage.

IntroductionDeveloping high-performance rechargeable lithium-ion batteries (LIBs) is among the most promising solutions to address the drastic increase in global demand of energy [1]. LIBs were introduced to the market in the 1990s by Sony and soon attracted a strong research interest due to their high energy density, stability, and no memory effect, as compared to other alternatives [2]. However, commercial LIBs mostly use graphite as the anode material, which possesses a relatively low theoretical specific capacity of ~372 mAh g -1 . This low capacity severely hampers the wide usage of LIBs in the surging consumer electronic devices and the large-scale energy applications such as hybrid electric vehicles, renewable power plants, and load levelling [3][4][5]. To accommodate the high-level requirements of these advanced applications, it is imperative to explore new electrode materials and novel designs for higher energy density, lower cost, flexibility, non-toxicity, and better stability.The recent advances in nanotechnology have offered a promising route to tackle these challenges [6][7][8][9]. As compared to the bulk materials, nanostructured materials possess a large surface area with excellent electrical, optical, and mechanical properties. Nanomaterials can enhance the performance of LIBs through two approaches. The first one is by using lowdimensional carbon-based nanomaterials to provide more efficient lithiation and delithiation In this work we solve these problems by fabricating the hybrid nano-urchin structure consisting of onion-like carbon/MnO 2 (OLC/MnO 2 ) using a simple and environmentallybenign hydro...
