“…), and metal oxides (SnO 2 , SnO, CuO, etc. ) due to their higher theoretical capacities arising from the redox of transition metals or the alloying/dealloying process during the discharge and charge process. However, the investigations on these materials have been plagued all the time due to the large volume change during cycling, which gravely induces the adverse cracking, pulverization of the primary structure, and accordingly fast capacity fading.…”

Sodium ion batteries (SIBs) are regarded as promising next‐generation energy storage devices due to their decent theoretical energy density and especially low cost. Here, micro/nanostructured Sb2O3 micro‐bundles consisting of many abreast nanoribbons were prepared via a simple hydrothermal route. In this unique structure, both ends of Sb2O3 nanoribbons with the thickness of ∼50 nm scatter with each other and extend radially from the center point, which not only reserves more space between nanoribbons to accommodate volume changes, but also provides plenty of open channels to facilitate the intimate contact of active species, conductive agents and electrolytes, thus efficiently shortening diffusion paths of Na+/e−. Evaluated as anode materials for SIBs, Sb2O3 micro‐bundles delivered outstanding electrochemical performance: high reversible capacity, superb rate capability, and stable cyclic ability. To get more insight, both the morphology evolution and the effect on electrochemical performance were explored as well, which further verified the significance of designing micro/nanostructured electrode materials in advanced energy storage fields.

In this paper, an efficient laser surface ablation strategy for producing binder‐free carbon‐coated nanocotton CoO‐Co integrated anode is reported. The fabrication process introduces in‐situ growing nanocotton‐like CoO on the surface of Co foil via ablating with a nanosecond laser. After that, coated with dopamine as carbon source, the CoO‐Co composite foil is heated in Argon atmosphere to form a CoO@C‐Co foil as an anode of LIB. The laser surface ablation exhibits high fabrication speed (~10 minutes) and significantly reduces the processing time. The obtained binder‐free CoO@C‐Co integrated anode shows a unique cotton‐like villous structure with large specific surface area and an active material/current collector integrated architecture, which provides a stabilized rapid electronic conduction path. When tested as an anode for LIBs, the CoO@C‐Co integrated anode possesses superior performance: First discharge capacity of 1301.5 mAh g−1 is achieved at a current density of 0.1 A g−1. Also at a high current density of 1.5 A g−1, the second discharge capacity of 791.7 mAh g−1 is achieved. After 800 cycles, reversible capacities of 799.8 mAh g−1 can still be achieved with an average coulombic efficiency of nearly 100%. In addition, this strategy is suitable for the production of other carbon coated transition metal oxides integrated anodes, such as NiO@C‐Ni, Fe2O3/Fe3O4@C‐Fe, and CuO/Cu2O@C‐Cu integrated anodes.

accessible lithium reserves are in remote or in politically sensitive areas. [5] This fact should sound the alarm for the expanded application of LIBs, because the increasing demand for LIBs could cause the price of lithium to skyrocket. It is even predicted that the world will run out of lithium supplies in the foreseeable future. [6][7][8] It is well known that sodium resources are more abundant (abundance: 23.6 × 10 3 mg kg −1 vs 20 mg kg −1 ) and vast (for example, the United States alone possesses 23 billion tons of soda ash which is a sodium-containing precursor) than lithium analog. Additionally, the trona (about $135-165 per ton), which could be used to produce sodium carbonate, has much lower cost than lithium carbonate (about $5000 per ton in 2010). [9,10] These two features endow SIBs with fascinating advantages for large-scale EES applications in the near future. Without doubt, SIBs also face big challenges: performance improvement and technological innovation. Although sodium has similar physical and chemical properties to lithium, the larger ionic radius of sodium ions compared with that of lithium ions restricts the insertion and extraction of sodium ions from the host materials commonly explored for LIBs. To address this problem, optimizing the chemical composition, tailoring the lattice structures, and regulating the morphologies of the host materials seem to be the most applicable strategies, and there have already been several excellent reviews. [11][12][13][14][15][16] As for technological innovation, the traditional fabrication processes mainly based on the slurrycasting method not only make SIBs typically rigid, thick, bulky, and heavy, but also reduce the overall volumetric/gravimetric energy density of the electrode. In the traditional slurry-casting method, the binders are insulating and electrochemically inactive, which can not only decrease the electrical conductivity, but also has a detrimental effect on the cycling stability resulting from some side effects between the electrolyte and inactive materials. In addition, the heavy weight of the binders, conductive additives and current collectors also reduces the volumetric/ gravimetric energy density of the overall electrode. Therefore, to enhance the battery performance and simplify the preparation process, the traditional slurry-casting method should be improved or even replaced; in other words, avoiding the use of binder, conductive additive, and metal current collector.In contrast, flexible electrodes are usually made from various active materials built on flexible conductive substrates without binder, conductive additive, and even metal current collector, Sodium-Ion Batteries
