Sodium metal battery(SMB)is regarded as a promising candidate for next-generation high-energy battery due to high theoretical capacity and abundant natural resources.However,the growth of sodium dendrites and large volume expansion during the processes of sodium plating and stripping seriously restrict the practical application of SMBs.Here,a three-dimensional skeleton of aluminum nanosheet arrays(Al NSARs)is constructed by a facile etching approach to achieve rapid and reversible Na plating/stripping.The Al NSARs with large geometric specific surface and plentiful cavities can provide rich active nucleation sites,reduce local current density and accommodate Na volume change,which lead to uniform deposition of sodium with dendrite-free morphology.As a result,Na plating/stripping on Al NSARs can stably operate over 650 cycles at 2 mA cm^(-2)/2 mAh cm^(-2)with average Coulombic efficiency(CE)of 100.0%and low potential polarization of 27 mV.Moreover,the full cell of Na_(s)V_(2)(PO_(4))_(3)||Al NSARs@Na can run for over 1800 cycles at a high rate of 20C.These superior properties,combined with relatively low cost and weight of Al,enable our AlNSARs to begreat prospect for practical applications.

The discovery of novel electrode materials promises to unleash a number of technological advances in lithium-ion batteries.V2O5 is recognized as a high-performance cathode that capitalizes on the rich redox chemistry of vanadium to store lithium.To unlock the full potential of V2O5,nanotechnology solution and rational electrode design are used to imbue V2O5 with high energy and power density by addressing some of their intrinsic disadvantages in macroscopic crystal form.Here,we demonstrate a facile and environmental-friendly method to prepare nanorods-constructed 3D porous V2O5 architectures(3 D-V2O5)in large-scale.The 3D porous architecture is found to be responsible for the enhanced charge transfer kinetics and Li-ion diffusion rate of the 3D-V2O5 electrode.As the result,the 3D-V2O5 surpasses the conventional bulk V2O5 by showing enhanced discharge capacity and rate capability(delivering 154 and 127 m Ah g^-1 at 15 and 20 C,respectively).

The latest view suggests the inactive core,surface pulverization,and poly sulfide shuttling effect of metal sulfides are responsible for their low capacity and poor cycling performance in sodium-ion batteries(SIBs).Whereas overcoming the above problems based on conventional nanoengineering is not efficient enough.In this work,erythrocyte-like CuS microspheres with an elastic buffering layer of ultrathin poly aniline(PANI) were synthesized through one-step selfassembly growth,followed by in situ polymerization of aniline.When CuS@PANI is used as anode electrode in SIBs,it delivers high capacity,ultrahigh rate capability(500 mAh gat 0.1 A g,and 214.5 mAh gat 40 A g),and superior cycling life of over 7500 cycles at 20 A g.A series of in/ex situ characterization techniques were applied to investigate the structural evolution and sodium-ion storage mechanism.The PANI swollen with electrolyte can stabilize solid electrolyte interface layer,benefit the ion transport/charge transfer at the PANI/electrolyte interface,and restrain the size growth of Cu particles in confined space.Moreover,finite element analyses and density functional simulations confirm that the PANI film effectively buffers the volume expansion,suppresses the surface pulverization,and traps the poly sulfide.

Zinc-ion batteries(ZIBs),in particular quasi-solid-state ZIBs,occupy a crucial position in the field of energy storage devices owing to the superiorities of abundant zinc reserve,low cost,high safety and high theoretical capacity of zinc anode.However,as divalent Zn^(2+)ions experience strong electrostatic interactions when intercalating into the cathode materials,which poses challenges to the structural stability and higher demand in Zn^(2+)ions diffusion kinetics of the cathode materials.Here,a microwave-assisted hydrothermal method is adopted to prepare pre-potassiated hydrated vanadium pentoxide(K_(0.52)V_(2)O_(5)·0.29H_(2)O,abbreviated as KHVO)cathode material,in which the potassium ions preinserted into the interlayers can act as“pillars”to stabilize the lamellar structure,and crystal water can act as“lubricant”to improve the diffusion efficiency of Zn^(2+)ions.Consequently,the KHVO displays high electrochemical properties with high capacity(∼300 mAh/g),superior rate capability(69 mAh/g at 5 A/g)and ultralong cycling performance(>1500 cycles at 2 A/g)in quasi-solid-state ZIBs.These superior Zn storage properties result from the large diffusion coefficient and highly stable and reversible Zn^(2+)(de)intercalation reaction of KHVO.

Sodium-ion batteries(SIBs)have become an auspicious candidate for largescale energy storage by cause of low cost,natural abundance,and similar working principle with lithium-ion batteries(LIBs).At present,there is an urgent need to explore superior anode materials with rapid and stable sodiation/desodiation.Herein,3D self-assembled VS4 curly nanosheets hierarchitectures(VS4-CN-Hs)are developed for SIB anodes,where VS4 possesses a large theoretical sodium storage capacity,and the building block of nanosheets has large exposed surface area to the electrolyte as well as the constructed hierarchitectures can provide abundant buffer space to alleviate the volume expansion.As a result,VS4-CN-Hs anode possesses excellent electrochemical performance under a wide voltage window of 0.01–3.0 V,such as high reversible capacity of 863 mA h g^(−1) at 0.1 A g^(−1),marvelous rate feature(444 mA h g^(−1) at 10 A g^(−1)),and extralong cycle stability(386 mA h g^(−1) after 1000 times at 5 A g^(−1)).

Sodium metal has been regarded as the potential alternative for metal batter-ies owing to its advantages of high theoretical capacity and abundant reserves.Nevertheless,propagation of Na dendrites can boost the interfacial instability of Na metal,retarding its practical implementation.Thus,the Na–Ga alloy layer is designed and fabricated by in situ rolling of metal Ga on the surface of Na metal.This alloy layer possesses good sodiophilicity,which can effectively pro-tect Na metal and favor the uniform Na+deposition,obtaining the inhibition of Na dendrites growth.Consequently,the symmetric cells assembled by the alloy-layer protected Na metal electrodes(NGAL-Na||NGAL-Na)have a long lifetime(468 h)even under a high plating/stripping capacity of 6 mAh cm^(−2) in carbon-ate electrolyte.The full battery of NGAL-Na||Na 3 V 2(PO 4)3 is able to sustain an excellent rate capability of 100 mAh g−1 after 500 cycles at 10 C under ambi-ent temperature.This work provides a new route to prevent metal anodes from severe dendrite growth,and paves the way toward safer and stable-performing metal-based rechargeable batteries.

Solid‐state Zn–air batteries(ZABs)hold great potential for application in wearable and flexible electronics.However,further commercialization of current ZABs is still limited by the poor stability and low energy efficiency.It is,thus,crucial to develop efficient catalysts as well as optimize the solid electrolyte system to unveil potential of the ZAB technology.Due to the low cost and versatility in tailoring the structures and properties,carbon materials have been extensively used as the conductive substrates,catalytic air electrodes,and important components in the electrolytes for the solid‐state ZABs.Within this context,we discuss the challenges facing current solid‐state ZABs and summarize the strategies developed to modify properties of carbon‐based electrodes and electrolytes.We highlight the metal−organic framework/covalent organic framework‐based electrodes,heteroatom‐doped carbon,and the composites formed of carbon with metal oxides/sulfides/phosphides.We also briefly discuss the progress of graphene oxide‐based solid electrolyte.

Potassium-ion batteries(PIBs)are attracted tremendous interest for large-scale energy storage systems(ESSs)owing to their economic merits.However,the main challenges of the PIBs are sluggish K-ion diffusion and large volume variations in the potassium repeated intercalation/deintercalation.Herein,mesoporous carbon nanosheet-assembled flowers(abbreviated as F-C)are designed as an original anode for superior-performance PIBs.Specifically,the F-C anode exhibits a high K-storage capacity(e.g.,381 mAh/g at 50 mA/g during the 2^(nd)cycle),excellent rate performance(e.g.,101 mAh/g at 2.0 A/g)and superior long cycle capability.Such excellent K-ion storage property is largely benefited from the large surface area(~141 m^(2)/g)and reasonable pore volume(0.465 cm^(3)/g),which not only stimulates rapid Kions diffusion and relieves the huge volume strain,but also exposes extensive active sites for K-ion capacitive storage.
