Opportunities coexist with challenges for the development of carbon-based cathodes with a high energy density applied for zinc ion hybrid capacitors(ZIHCs).In the present study,a facile and effective surface engineering approach is demonstrated to greatly improve the energy storage ability of commercial carbon paper(CP)in ZIHC.Benefiting from the introduced oxygen functional groups,larger surface area and improved surface wettability upon air calcination,the assembled aqueous ZIHC with the functionalized carbon paper(FCP)exhibits a much higher areal capacity of 0.22 mAh/cm^(2)at 1 mA/cm^(2),outperforming the counterpart with blank CP by over 5000 times.More importantly,a superior energy density and power density of 130.8μWh/cm^(2)and 7460.5μW/cm^(2),are respectively delivered.Furthermore,more than 90%of the initial capacity is retained over 10000 cycles.This surface engineering strategy to improve the energy storage capability is potentially applicable to developing a wide range of high-energy carbon electrode materials.

Stibium(Sb)metal with high theoretic capacity,suitable negative working window and inexpensive nature are promising anode material for advanced aqueous alkaline batteries(AABs).However,the further development of Sb anode is severely hindered by the low capacity and poor rate capability which is originated from deficient adsorption of[Sb(OH)_(4)]^(-)and its sluggish desolvation kinetics.Herein,a nitrogen doped carbon cages(NCCs)substrate is constructed as high capacity and rate capability anode by promoting the adsorption and following desolvation process of[Sb(OH)_(4)]^(-)via the enhanced attraction toward(OH)-in the solvated[Sb(OH)_(4)]^(-).Consequently,the designed Sb/NCCs anode delivers a high capacity of 627 m Ah g^(-1)with an average 95%Sb utilization,an outstanding coulombic efficiency(CE)of 95%and an impressive lifespan(>110 h).Meanwhile,the Ni_(3)Se_(2)//Sb/NCCs batteries show great capacity retention of 86.7%after 2000 cycles with an areal capacity of 0.52 m Ah cm^(-2).Implementation of the designed anode allows for the construction of Sb-based AABs with enhanced rate capability,energy density and cycling performance.

Zinc-ion hybrid supercapacitors(ZHSCs)have garnered increasing attention as promising energy storage devices in recent years,as they combine the advantages of high-energy Zn-ion batteries and high-power supercapacitors.However,the development of ZHSCs is still in its infancy and there are many bottlenecks to overcome.In particular,the challenge induced by the limited ion adsorption capability of carbon-positive electrodes severely restricts the energy density of ZHSCs.Therefore,it has become a key issue to design novel carbon-positive electrodes that enable high energy density yet do not deteriorate the intrinsic power capability and long-term durability.This study focuses on recent achievements in synthesis,morphology,and electrochemical performance of various carbon materials applied in ZHSCs.The modification strategies to optimize their electrochemical performance are briefly summarized.In addition,current challenges and future opportunities in this field are also outlined.This review will be beneficial to provide an organized framework for the research systems of carbon-positive electrodes and develop novel ZHSCs with high energy density.

Ultrasonic stimulation induced polarization behaviors in ferroelectric materials have been extensively explored in catalytic degradations.However,the ultrasonic wave similarly can realize dye degradation by the sonocatalysis behavior,which is always neglected in most reports on in-situ ultrasound-induced piezoelectric catalysis,so that people might overestimate piezocatalytic contributions.For this,we designed a series of visible light sensitive bismuth layered ferroelectric materials(BLFMs),M_(0.5)Bi_(2.5)Nb_(2)O_(9)(MBN,M=Li,Na,and K).It is found that the cavitation-induced degradation rates of Rhodamine B(RhB)strongly depend mechanical stirring speeds under a fixed ultrasonic power,which gradually increases with it,and reaches 77.9%(500 rpm and 3 h).Under lower stirring speed and reaction time(<50 rpm and 2 h),the cavitation effect is almost negligible,only piezocatalysis behavior occurs,which can be used as a key condition to distinguish the piezocatalysis and sonocatalysis.In particular,the degradation rate constant of Na_(0.5)Bi_(2.5)Nb_(2)O_(9) catalyst reaches up to 4.943×10^(-2) min^(-1) by the coupling of sonocatalysis,piezocatalysis and photocatalysis,which is much higher than that of single photocatalysis(0.491×10^(-2) min^(-1)),piezocatalytic(1.6×10^(-3) min^(-1)),and sonocatalysis(0.756×10^(-2) min^(-1)).These results may provide a feasible strategy of further improving catalytic degradation efficiency,and accurately determining the sonocatalysis and piezocatalysis contribution.

Aqueous zinc ion battery(ZIB)with many virtues such as high safety,cost-effective,and good environmental compatibility is a large-scale energy storage technology with great application potential.Nevertheless,its application is severely hindered by the slow diffusion of zinc ions in desirable cathode materials.Herein,a technique of water-incorporation coupled with oxygen-vacancy modulation is exploited to improve the zinc ions diffusion kinetics in vanadium pentoxide(V_(2)O_5)cathode for ZIB.The incorporated water molecules replace lattice oxygen in V_(2)O_5,and function as pillars to expand interlayer distance.So the structural stability can be enhanced,and the zinc ions diffusion kinetics might also be promoted during the repeated intercalation/deintercalation.Meanwhile,the lattice water molecules can effectively enhance conductivity due to the electronic density modulation effect.Consequently,the modulated V_(2)O_5(H-V_(2)O_5)cathode behaves with superior rate capacity and stable durability,achieving 234 mA h g^(-1)over 9000 cycles even at 20 A g^(-1).Furthermore,a flexible all-solid-state(ASS)ZIB has been constructed,exhibiting an admirable energy density of 196.6 Wh kg^(-1)and impressive power density of 20.4 kW kg^(-1)as well as excellent long-term lifespan.Importantly,the assembled flexible ASS ZIB would be able to work in a large temperature span(from-20 to 70℃).Additionally,we also uncover the energy storage mechanism of the H-V_(2)O_5 electrode,offering a novel approach for creating high-kinetics cathodes for multivalent ion storage.

The development of zinc ion batteries (ZIBs) with large capacity,high rate,and durable cathode material is a crucial and urgent task.Ni Co_(2)O_(4)(NCO) has received ever-growing interest as a potential cathode material for ZIBs,owing to the high theoretical capacity,rich source,cost-effective,and versatile redox nature.However,due to the slow dynamics of the NCO electrodes,its practical application in highperformance systems is severely limited.Herein,we report an electron density modulated NCO nanosheets (N-NCO NSs) with high-kinetics Zn^(2+)-storage capability as an additive-free cathode for flexible all-solid-state (ASS) ZIBs.By virtue of the enhanced electronic conductivity,improved reaction kinetics,and increased active sites,the optimized N-NCO NSs electrode delivers a high capacity of 357.7 m Ah g^(-1)at 1.0 A g^(-1)and a superior rate capacity of 201.4 m Ah g^(-1)at 20 A g^(-1).More importantly,a flexible ASS ZIBs device is manufactured using a solid polymer electrolyte of a poly (vinylidene fluoride hexafluoropropylene)(PVDF-HFP) film.The flexible ASS ZIBs device shows superb durability with 80.2%capacity retention after 20,000 cycles and works well in the range of-20–70℃.Furthermore,the flexible ASS ZIBs achieves an impressive energy density as high as 578.1 W h kg^(-1)with a peak power density of 33.6 k W kg^(-1),substantially outperforming those latest ZIBs.This work could provide valuable insights for constructing high-kinetics and high-capability cathodes with long-term stability for flexible ASS ZIBs.

Aqueous Zn//MnO2 batteries are emerging as promising large-scale energy storage devices owing to their cost-effectiveness,high safety,high output voltage,and energy density.However,the MnO2 cathode suffers from intrinsically poor rate performance and rapid capacity deterioration.Here,we remove the roadblock by compositing MnO2 nanorods with highly conductive graphene,which remarkably enhances the electrochemical properties of the MnO2 cathode.Benefiting from the boosted electric conductivity and ion diffusion rate as well as the structural protection of graphene,the Zn//MnO2-graphene battery presents an admirable capacity of 301 mAh g^-1 at 0.5 A g^-1,corresponding to a high energy density of 411.6 Wh kg^-1.Even at a high current density of 10 A g^-1,a decent capacity of 95.8 mAh g^-1 is still obtained,manifesting its excellent rate property.Furthermore,an impressive power density of 15 kW kg^-1 is achieved by the Zn//MnO2-graphene battery.
