Sodium-ion batteries (SIBs) are emerging as a possible substitute for lithium-ion (LIBs) in low-cost and large-scale electrochemical energy storage systems owing to the lack of lithium resources. The properties SIBs correlated electrode materials, while performance materials is significantly affected by morphologies. In recent years, several kinds anode involving carbon-based anodes, titanium-based conversion alloy-based organic anodes have been systematically researched develop high-performance SIBs. Nanostructures huge specific surface areas short ion diffusion pathways. However, excessive solid electrolyte interface film worse thermodynamic stability hinder application nanomaterials Thus, strategies constructing three-dimensional (3D) architectures developed compensate flaws nanomaterials. This review summarizes achievements 3D architectures, including hollow structures, core-shell yolk-shell porous self-assembled nano/micro-structures, discusses relationship between sodium properties. Notably, intention improve integrating benefits various structures components. development architecture construction will be essential future SIB applications.

Transition-metal tellurides have been investigated as novel anode materials for application in sodium-ion batteries (SIBs) due to their rich active sites and unique controllable layered nanostructures. However, the weak structural strength inferior intercalation/deintercalation kinetics inhibit development of transition-metal tellurides. In this work, MoTe

Abstract Room‐temperature sodium‐sulfur (RT Na‐S) batteries hold immense promise as next‐generation energy storage systems, owing to their exceptionally high theoretical capacity, abundant resources, eco‐friendliness, and affordability. Nevertheless, practical application is impeded by the shuttling effect of sodium polysulfides (NaPSs) sluggish sulfur redox kinetics. In this study, an advanced strategy designing 3D flower‐like molybdenum telluride (MoTe 2 ) efficient catalyst promote for RT Na‐S presented. The unique MoTe effectively prevents NaPS simultaneously offers active catalytic sites facilitating polysulfide redox. Consequently, obtained /S cathode delivers outstanding initial reversible capacity 1015 mAh g −1 at 0.1 C, along with robust cycling stability retaining 498 1 C after 500 cycles. addition, pouch cells are fabricated additive deliver ultrahigh discharge 890 remain stable over 40 cycles under practically necessary conditions, demonstrating potential in commercialization batteries.

The use of TiNb2O7 (TNO) as an anode material for Li-ion battery is attracting tremendous attention because its stable structure and high theoretical capacity. However, the inherent poor electronic conductivity ionic restrict practical application. Herein, we designed prepared zirconium-doped nanospheres (Zrx-TNO NSs, x = 0, 0.05, 0.010) with pores through a simple hydrolysis method to adjust lattice spacing electron distribution. nanosphere-structured materials can not only prevent aggregation active but also provide more channels Li+ electrons' transportation. Meanwhile, X-ray diffraction coupled high-resolution transmission microscopy results verified crystal increasement. photoelectron spectrum exhibited partial reduction metal atoms. As result, Zr0.05-TNO NSs showed improved cycling stability in half cell (i.e., delivers reversible capacity 170 mA h/g at 5 C after 1000 cycles). It excellent performance rate capabilities 260.0 177.8 0.5 10 C, making it highly competitive quick-charging lithium-ion batteries.

By changing the diameter of carbon nanotubes (CNTs), phase internal phosphorus could be adjusted, which was testified by spherical-chromatic aberration-corrected transmission electron microscopy. Phosphorus inside a double-walled CNT (P@DWCNT) delivers stable capacity 837 mA h g–1 after 700 cycles at 1.0 A g–1. 155 delivered P@DWCNT when forming full cell with LiFePO4 cathode. According to in situ Raman spectrum, strain (24 GPa) on DWCNTs caused volume expansion during lithiation totally relieved along axis end delithiation process, showing high reversibility. This is because filling rate an appropriate level and are not fully filled, thus preventing from escaping further pulverization. single-walled (P@SWCNT) can only deliver limited since its single layer cannot sustain integrality multiple insertion/extraction processes Li+. Because too much deposited multiwalled (P@MWCNT) sample external tends break off rapidly upon cycling, P@MWCNT shows fast degradation. The anodes thoroughly studied galvanostatic intermittent titration pseudocapacitance investigations reveal size-dependent confining effect.

Owing to favorable cell voltage exceeding 3 V and cost-effectiveness, sodium dual-ion batteries (Na-DIBs) have gained increasing emphasis, however, they are hampered by the availability of suitable anode. Here, an exotic Na-DIB anode, composed Co1.67Te2 nanoparticles embedded within porous carbon nanofibers (Co1.67Te2@PCFs), has been developed a combination electrostatic spinning specialized thermal etching process. The confined space layers show energetic capability for Na+ storage enhanced kinetic behavior cell, further verified density functional theory (DFT) calculations. Additionally, formed thin, uniform, inorganic-rich solid electrolyte interphase (SEI) on surface Co1.67Te2@PCFs after cycling reduces consumption facilitates uniform flow Na+.
