Smart construction of ultraflexible electrodes with superior gravimetric and volumetric capacities is still challenging yet significant for sodium ion batteries (SIBs) toward wearable electronic devices. Herein, a hybrid film made of hierarchical Fe1−xS‐filled porous carbon nanowires/reduced graphene oxide (Fe1−xS@PCNWs/rGO) is synthesized through a facile assembly and sulfuration strategy. The resultant hybrid paper exhibits high flexibility and structural stability. The multidimensional paper architecture possesses several advantages, including rendering an efficient electron/ion transport network, buffering the volume expansion of Fe1−xS nanoparticles, mitigating the dissolution of polysulfides, and enabling superior kinetics toward efficient sodium storage. When evaluated as a self‐supporting anode for SIBs, the Fe1−xS@PCNWs/rGO paper electrode exhibits remarkable reversible capacities of 573–89 mAh g−1 over 100 consecutive cycles at 0.1 A g−1 with areal mass loadings of 0.9–11.2 mg cm−2 and high volumetric capacities of 424–180 mAh cm−3 in the current density range of 0.2–5 A g−1. More competitively, a SIB based on this flexible Fe1−xS@PCNWs/rGO anode demonstrates outstanding electrochemical properties, thus highlighting its enormous potential in versatile flexible and wearable applications.

abundance, as well as almost unlimited sodium resources on earth, sodium-ion batteries (SIBs or NIBs) are continuously attracting increasing attentions in both of the academic and industrial fields as competitive alternatives for the possible replacement of LIBs. [2][3][4] Similar with the performance limit issues in LIB systems, the key challenges for the application and commercialization of NIBs are regarded as the appropriate electrode material selection and design. [5][6][7] Among the various candidates for NIB anodes, titanium dioxide (TiO 2 ) is a promising choice on account of its several superiorities such as structural stability based on intercalation mechanism, safety insurance due to the high working voltage, environmental friendly, and low cost. [8][9][10][11][12][13] However, the relatively low specific capacity and inferior rate capability of TiO 2 -based anode materials make them still have the necessity of promotion and optimization. To relieve these natural drawbacks, hollow, hierarchical, and porous architectures are proved to be effective for meliorating the sluggish Na + diffusion kinetics, increasing the Insertion-type anode materials with beneficial micro-and nanostructures are proved to be promising for high-performance electrochemical metal ion storage. In this work, heterostructured TiO 2 shperes with tunable interiors and shells are controllably fabricated through newly proposed programs, resulting in enhanced pseudocapacitive response as well as favorable Na + storage kinetics and performances. In addition, reasonably designed nanosheets in the extrinsic shells are also able to reduce the excess space generated by hierarchical structure, thus improving the packing density of TiO 2 shperes. Lastly, detailed density functional theory calculations with regard to sodium intercalation and diffusion in TiO 2 crystal units are also employed, further proving the significance of the surface-controlled pseudocapacitive Na + storage mechanism. The structure design strategies and experimental results demonstrated in this work are meaningful for electrode material preparation with high rate performance and volume energy density.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.

conductivity, and high volumetric energy density. [8][9][10] Moreover, Se is a reasonably priced element, being around $ 32 per kg when purchased in industrial quantities. [4] Comparable to the S cathode, a Se cathode also has major concerns regarding volume expansion of Se (>97%) and shuttle effects by polyselenide intermediates. [11,12] To address these concerns, most studies have focused on the incorporation of functional materials such as porous carbons, conductive polymers, and metal oxides. [5][6][7] In general, the Se cathode is prepared by complicated multistep processes, which are consisted of encapsulating of Se into porous carbon (Se/C composite), slurry preparation using high energy ball-mixing of Se/C composites and other additives, deposition of the slurry on a current collector, and finally pressing the cathode. [11][12][13] In the Se cathode, there exist complex interfaces due to multicomponents system. Furthermore, all the additives do not contribute to electrochemical redox reaction lowering energy density and polymer binder even can increase interfacial resistance. Thus, it would be highly desirable to provide a simple fabrication process and stable cycling to Li-Se battery. [14][15][16] Herein, we introduced a new design of Se cathode, which was simply prepared by electrochemical deposition of Se on Nifoam and subsequent coating of a thin layer of solid polymer electrolyte (SPE). The electrodeposition of Se on Ni-foam is an easy process, and direct contacts of Se on current collector provide facile charge transport. The SPE was easily prepared via crosslinking reaction of poly(ethylene glycol) diglycidyl ether (DE-PEG) and diamino-poly(propylene oxide) (DA-PPG) with subsequent immersion in a LiPF 6 based carbonate electrolyte. The elastic SPE layer is able to protect the delamination problem of Se from the Ni-foam controlling the volume expansion of Se, to provide facile ionic pathway, and to suppress Li-dendrite growth. The designed "One-piece" Se cathode was produced by facile manufacturing process and exhibited an ultrastable cycling performance of 0.001% capacity degradation per cycle for 3000 cycles at 1 C rate.A schematic preparation of the one-piece Se cathode is shown in Figure 1. In the preparation of the one-piece Se cathode, Se was electrodeposited on the Ni-foam and a prepolymer solution of SPE was poured on the Se/Ni-foam to fill the pore. The prepolymer was thermally cross-linked and liquid electrolyte was impregnated. At the bottom of Ni-foam, a thin layer (≈20 µm) of SPE was formed which was directly contacted with Li metal foil. Moreover, the thickness of SPE in A high-performance Li-Se battery is demonstrated by adopting a novel Se cathode design. The Se cathode is a one-piece body combined with a Se deposited current collector and a solid polymer electrolyte (SPE). In the preparation of the Se cathode, Se is electrodeposited on Ni-foam, and the pores are filled with SPE layers. Through this electrodeposition, the cathode is easily fabricated, and charge transports are facile...
