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...

This review covers recent advances in conjugated polymers and their application in energy storage. Conjugated polymers are promising cost-effective, lightweight, and flexible electrode materials. The operating principles of conjugated polymers are presented within the framework of their potential for energy storage. Special focus is given to polyaniline electrodes. Recent advances are reviewed including new methods of synthesis, nanostructuring, and assembly. Also, covered are applications that take full advantage of the mechanical properties of conjugated polymers and future applications of these novel materials.

“…The superior LIBs performances of this electrode material can be explained as follows: (i) the hollow structures of the SnS 2 @C could provide extra interior space to accommodate the volume expansion/contraction during the Li + insertion/ extraction process [39]. (ii) The carbon shells prevented the restacking of SnS 2 microspheres or the crumbling of electrode material during continuous cycling [40]. (iii) The coated amorphous carbon in the composite can serve as the conductive species, which decrease the inner resistance of the LIBs, thus leading to a higher specific capacity and better rate capability [41].…”
