“…The lower capacity for sodium storage might be mostly attributed to the sluggish reaction kinetics of sodiation/desodiation because of much larger ionic radius of Na + ion, indicating an incomplete conversion reaction during this sodiation/desodiation process. Even though the specific capacity for NCO@CFC electrode as SIB is lower than lithium storage, the sodium storage performance of the present NCO@CFC nanowire arrays in terms of capacity, cycling stability and rate capability are better than those of other reported electrode materials for SIBs, [44][45][46][47] suggesting that NCO@CFC nanowire arrays are a promising candidate as electrode material for SIBs.

The growth of three-dimensional (3D) porous NiCo 2 O 4 nanowire arrays on carbon fiber cloth (denoted as NCO@CFC) via a facile low-cost solution method combined with a subsequent annealing treatment is reported. The structure and morphology of the materials were characterized by X-ray diffraction, fieldemission scanning electron microscopy, and transmission electron microscopy. Owing to the unique 3D hierarchical architecture, the NCO@CFC nanowires as flexible electrode material for Lithium-ion batteries exhibit stable cycling performance (92.3% retention after 100 cycles), fairly high rate capacity (507 mAh g -1 at 4000 mA g -1 ), and enhanced lithium storage capacity. When employed as electrode material for Sodium-ion batteries, the NCO@CFC is investigated based on such a 3D ordered array structure and exhibits similar charge/discharge characteristic and feasible electrochemical performance. The greatly improved electrochemical performance could be ascribed to the 3D porous nanostructure of the NCO@CFC nanowire arrays with a novel carbon skeleton, which provides enough space to ease volume expansion during Li + /Na + insertion/extraction process and facilitates rapid transport of ions and electrons.

Graphical AbstractVO 2 (B) is identified as a potential high-energy-density anode for lithium-and sodium-ion batteries.Abstract VO 2 (B) is an interesting cathode candidate in lithium-ion batteries with a high theoretical capacity and fast charge/mass transfer rate. Most of the studies on this material have focused on the lithium insertion reaction in the range of 4.0 -1.0 V. In this paper, VO 2 /rGO nanocomposite was prepared by a microwave-assisted solvothermal method and investigated in both lithium-ion and sodium-ion batteries as a potential anode. The VO 2 (B) nanorods have an average diameter of ~ 200 nm, and is encapsulated by reduced graphene oxide (rGO) nanosheets. Electrochemical results reveal that the VO 2 /rGO electrodes exhibit stable cycling and good rate performance in both Li and Na cells. Reversible capacities of 400 mAh g -1 over 400 cycles (vs. Li/Li + ) and 200 mAh g -1 over 200 cycles (vs. Na/Na + ) have been achieved, indicating it is potential as an anode candidate either in lithium-or sodium-ion batteries. Nevertheless, the reaction mechanisms seem to be different in Li and Na cells. The crystal structure of VO 2 (B) is maintained at a low discharge potential of 0.05 V in lithium-ion cells, while phase amorphization occurs in sodiumion cells below 0.5 V. This result is consistent with the previous study on TiO 2 , further confirming that some stable metal oxides may show rather different behaviors in Na cells than expected.

“…Among these new alternative anode materials, transition metal oxides such as CoO x , NiO, CuO and FeO x , which store charge through conversion reactions, have received particular attention because of a high capacity (up to 1000 mA h g À1 ), 2-3 times greater than the graphite electrode [10][11][12][13]. One significant advantage of conversion-type anodes is the versatile selection of available materials.…”
