Na metal anode, benefiting from its high theoretical capacity and lowest electrochemical potential, ~sone of the most favorable candidates for future Na-based batteries with high energy density. Dendritegrowth, volume change and high reactivity are the formidable challenges in terms of good cycling perfor-mance and high Coulombic efficiency as well as an expected safety guarantee of Na metal anode for thepractical application. Solid electrolyte interphase （SEI） layer as an indispensable component of a battery,its formation and stability play the critical role in the feasibility of Na metal anode. In this review, wefirst discuss the current consideration and challenges of Na metal anode, and then summarize severalstrategies to suppress dendrite growth and improve electrochemical performance, including interface en-gineering, electrolyte composition, electrode construction, and so on. Finally, the conclusion and futureperspective of potential development on Na metal anode are proposed.

Here,we report the synthesis of hard carbon materials(RH) made from natural rice husk through a single pyrolysis process and their application as an anode in sodium-ion batteries.The studies show that the electrochemical properties of RHs are affected by the treatment temperatures,which determine the materials morphology,in particular,their degree of graphitization and extent of continuous channels(nanovoids).The latter are accessible to sodium ions and significantly contribute to charge storage capacity of the produced anodes.The RHs obtained at 1600 °C deliver the highest reversible capacity of276 mAh g^(-1) mainly due to insertion of sodium ions into the nanovoids.This work deepens the basic understanding of the influence of the carbonization temperature on the sodium storage mechanism.

Na-ion batteries(NIBs)are gradually attracting much attention as an alternative to lead-acid batteries and supplement to Li-ion batteries(LIBs)owing to the abundant Na resources and excellent cost-effectiveness.Since the most commonly used graphite as an anode material in LIBs cannot be inherently used in NIBs,tremendous efforts have been made to advance the fundamental understanding and design of suitable anode materials for NIBs,including the improvement of Na storage capacity and the study on Na storage mechanisms.According to all these studies,disordered carbons are now the most promising anode candidates for NIBs.In this review,we discuss the current challenges and remaining problems to be solved in the area of disordered carbon anode materials for NIBs and provide future insights and research directions.

Organic materials, especially the carbonyl compounds, are promising anode materials for room temperature sodium-ion batteries owing to their high reversible capacity, structural diversity as well as eco-friendly synthesis from bio-mass. Herein, we report a novel anthraquinone derivative, C_(14)H_6 O_4 Na_2 composited with carbon nanotube(C_(14)H_6 O_4 Na_2-CNT), used as an anode material for sodium-ion batteries in etherbased electrolyte. The C_(14)H_6 O_4 Na_2-CNT electrode delivers a reversible capacity of 173 mAh g^(-1) and an ultra-high initial Coulombic efficiency of 98% at the rate of 0.1 C. The capacity retention is 82% after 50 cycles at 0.2 C and a good rate capability is displayed at 2 C.Furthermore, the average Na insertion voltage of 1.27 V vs. Na^+/Na makes it a unique and safety battery material, which would avoid Na plating and formation of solid electrolyte interface. Our contribution provides new insights for designing developed organic anode materials with high initial Coulombic efficiency and improved safety capability for sodium-ion batteries.

The anionic redox reaction(ARR)is a promising charge contributor to improve the reversible capacity of layeredoxide cathodes for Na-ion batteries;however,some practical bottlenecks still need to be eliminated,including a low capacity retention,large voltage hysteresis,and low rate capability.Herein,we proposed a high-Na content honeycomb-ordered cathode,P2–Na_(5/6)[Li_(1/6)Cu_(1/6)Mn_(2/3)]O_(2)(P2-NLCMO),with combined cationic/anionic redox.Neutron powder diffraction and X-ray diffraction of P2-NLCMO suggested P2-type stacking with rarely found P6322 symmetry.In addition,advanced spectroscopy techniques and density functional theory calculations confirmed the synergistic stabilizing relationship between the Li/Cu dual honeycomb centers,achieving fully active Cu^(3+)/Cu^(2+) redox and stabilized ARR with interactively suppressed local distortion.With a meticulously regulated charge/discharge protocol,both the cycling and rate capability of P2-NLCMO were significantly.

Layered oxides are one of the most prom ising cathode materials for sodium ion batteries (NIBs), however, the relatively low working voltage hinders the increase of energy density thus limiting the application scenarios of NIBs. Here we prepared and investigated a series of Sn^4+ substituted NaO.67NiO.33M na67-xSnxO2 (x = 0.10, 0.20, 0.30, 0.33) and found that Sn-substitution can induce three effects: promoting O3-stack formation, sm oothing the voltage profile and increasing the working voltage to -3.6 V. This study would enrich the knowledge of Sn-substitution and give guide to the better design of high-voltage cathode materials for NIBs.

Na-ion batteries(NIBs)have received significant interest as potential candidates for large-scale energy storage owing to the widespread distribution of sodium and superior low-temperature performance.However,their commercial application is usually hindered by the high production cost and inadequate performance for electrode materials,particularly for cathodes.Na_(3)(VOPO_(4))_(2)F(NVOPF)has been recognized as one of the most promising cathodes for high-energy NIBs owing to the high working voltage and energy density.Here,we report a facile highly efficient room-temperature solution protocol for large-scale synthesis of NVOPF cathode for NIBs.By simply regulating pH,NVOPF can be obtained,which delivered a discharge capacity of 120.2 mAh g^(-1) at 0.1 C and 72%capacity retention over 8000 cycles at 25 C.Besides,the kilogram-level NVOPF products have been synthesized,and 26650 cylindrical cells were fabricated,which exhibit excellent cycling stabilities,remarkable lowtemperature performance with comparable safety features.We hope our findings could provide insights on the industrial application of NVOPF in NIBs.

Recently,sodium-ion batteries(SIBs),regarded as promising supplements for lithium-ion batteries(LIBs),especially in the large-scale energy storage field,are attracting more and more attention.However,the limited suitable cathode materials hinder the wide commercialization of SIBs.Given this aspect,in this work,a new layered oxide with 4d metal Tin was synthesized and investigated as cathode material for SIBs.Two optimized sodium-deficient O3-Na_(0.9)Ni_(0.45)Sn_(0.55)O_2and O3-Na_(0.9)Ni_(0.4)Mn_(0.1)Sn_(0.5)O_2were selected for comprehensive investigation,both of which exhibited high operating voltage of around 3.45 V with smooth charge/discharge curves.In comparison,O3-Na_(0.9)Ni_(0.4)Mn_(0.1)Sn_(0.5)O_2shows a higher reversible capacity(65 m A h/g,0.1 C),better rate capability and cycling stability than that of O3-Na_(0.9)Ni_(0.45)Sn_(0.55)O_2(50 mA h/g,0.1 C),indicating that a small amount of Mn-substitution can improve the electrochemical performance.This work presents a new possibility of discovering potential cathode candidates by exploring the Tin-based layered oxides.
