“…Xia et al Figs. 4(e) and 4(f). Jin et al 44 also reported a facile and direct synthesis of large-scale cobalt monoxide (CoO) porous nanowire arrays with robust mechanical adhesion to°exible conductive Ti foil through the complete pyrolysis of cobalt-hydroxide-carbonate precursors. In addition, on the basis of a facile hydrothermal route, Wang et al 73 synthesized a series of novel layered hydroxide lanthanum (LHL) crystalline nanowires with hierarchical pores.…”

“…43,112 Notably, the nanostructured porous materials with large surface areas will lead to multiple advances in the performance of Li-ion batteries, such as providing shorter path lengths for both electron and Li ion transport, a higher electrode/ electrolyte contact area, a better accommodation of the strain of the Li ion insertion/extraction, etc. Jiang et al 44 examined the electrochemical rate capability of porous CoO nanowires with Li ion insertion and extraction at di®erent rates, and found that this kind of porous CoO nanowires supported on°exible conductive substrate (Ti foil) exhibit good high-rate capability at the rate of 1 C (716 mA g À1 ), 2 C (1432 mA g À1 ), 4 C (2864 mA g À1 ) and 6 C (4296 mA g À1 ), respectively. The as-revealed completely reversible electrochemical properties and unique advantages should originate from the typical porous 1D nanostructured architecture.…”

“…[24][25][26][27][28][29] The extremely high surface-to-volume ratios contribute to large quantities of reactive interfaces, which make this kind of materials extremely sensitive to species adsorbed on the inner and outer surfaces, resulting in excellent sensitivity and selectivity. Meanwhile, 1D porous nanowires have shown desired functions in catalysis, [30][31][32][33][34][35][36] photocatalyst, 35,37 sensors, 36,[38][39][40] fuel cells, 41 Li-ion batteries, 37,[42][43][44][45][46][47] super-capacitors, 48,49 water treatment [50][51][52] and so forth. As far as the literature is concerned, there is no special review focusing on the typical 1D porous nanowires (arrays) referring to synthesis and applications till now.…”

In recent years, particular attention has been drawn to one-dimensional (1D) porous nanowires due to their high surface-to-volume ratios as well as the as-revealed excellent performance in varieties of applications. This review begins with a wide introduction to the as-reported various preparation methods for the typical 1D porous nanowires mainly consisting of template-free method (i.e., chemical etching, chemical vapor deposition, hydrothermal, electrospinning, gassolid reaction, etc.) and template-assisted method (i.e., using hard template and soft template, respectively). Based on the classi¯cation of design and preparation strategies, the as-evolved various nonmetallic and metallic 1D nanoporous materials with varied microstructural features have been highlighted, followed by the corresponding description and discussion on their typical applications in catalysis, sensors, rechargeable batteries, solar cells, super-capacitors, water treatment, random lasers and so forth.

“…For example, forming composites with conductive materials such as carbon is a very common and useful method, but often reduces the mass specific capacity [11,12]. So, preparing materials with a special morphologies such as a porous structure [13][14][15][16], nanoarrays [6,17], microspheres [18][19][20][21][22] and some others [23] to enhance the electrochemical performance has attracted much attraction.…”

“…Good results at higher C rates have been obtained by combining nanoscale and porosity. In particular, the synthesis of CoO porous nanowire arrays with robust mechanical adhesion to a flexible conductive Ti foil exhibit good high-rate capability at a rate of 1C (716 mA g À1 ), 2C (1432 mA g À1 ), 4C (2864 mA g À1 ), and 6C (4296 mA g À1 ), respectively [488]. Hierarchically self-assembled mesoporous CoO nanodisks synthesized by the reaction of cobalt acetate tetrahydrate with hydrazine hydrate in solution followed by heat treatment in an inert atmosphere delivered a capacity of 1118.6 mAh g À1 after 50 discharge-charge cycles at 200 mA g À1 and excellent cycling performance: 633.5 mAh g À1 after 400 discharge-charge cycles at 800 mA g À1 [489].…”

Lithium-ion batteries (LiBs) have made considerable progress since the first commercial one by Sony in 1991, which had LiCoO 2 and graphite as active elements of the positive and negative electrodes, respectively. The LiBs are now the primary energy storage devices in the transportation and communications, from portable use in computers, up to electric and hybrid vehicles. More recently, they have also been used as back-up supply units, frequency regulators (load leveling) to integrate on smart grids the electricity produced by windmills and photovoltaic plants (for a recent review, see [1]). These applications require high energy densities, high power, and safety among others. Considerable efforts have been made to propose other electrodes to fulfill these requirements. We have recently reviewed the works and progress concerning the materials for the positive electrode [2][3][4][5][6]. The present work is devoted to the materials for the negative electrode counterpart. It is common to use the terminology anode and cathode for the negative and positive electrodes, respectively, although the electrodes play alternatively the role of anode and cathode during the charge and discharge process. We shall use this terminology in the following for conciseness purposes only.An ideal active anode element should fulfill the following requirements as follows: (1) It must be light and accommodate as much Li as possible to optimize the gravimetric capacity. (2) Its redox potential with respect to Li 0 /Li + must be as small as possible at any Li-concentration. The reason is that this potential is subtracted to the redox potential of the cathode material to give the overall voltage of the cell, and smaller voltage means smaller energy density. (3) It must possess good electronic and ionic conductivities since faster motion of the lithium ions and the electrons also mean higher power density of the cell. (4) It must not be soluble in the solvents of the electrolyte and not react with the lithium salt. (5) It must be safe, i.e. avoid any thermal runaway of the battery, a criterion that is not independent of the previous one, but deserves special attention, especially for use in transportation such as electric vehicles and planes. (6) It must be cheap and environmentally friendly. The different materials proposed as anode elements for Li-ion batteries must be discussed with respect to these different criteria.The graphite is still the most used anode material and is still the reference. The first works giving evidence of the insertion of lithium in graphite date from 1955 [7], confirmed by the synthesis of LiC 6 in 1965 [8]. The synthesis of LiC 6 , however, was not obtained by electrochemical process at that time. Another decade was spent before Besenhard and Eichinger discovered the reversible intercalation of lithium in graphite, proposing this material as an anode in 1976 [9,10]. Increasing the Li content in LiC 6 is possible [8], but no reversible cycling beyond LiC 6 could ever be obtained. The graphite anode can thus be cyc...
