文摘Developing electrochemical energy storage devices with high energy and power densities,long cycling life,as well as low cost is of great significance.Hybrid metal-ion capacitors(MICs),commonly consisting of high energy battery-type anodes and high power capacitor-type cathodes,have become a trade-off between batteries and supercapacitors.Tremendous efforts have been devoted to searching for high-performance electrode materials due to poor rate capability of anodes,low capacity of cathodes,and interior sluggish kinetic match.Carbon materials with large surface area,good electrical conductivity and stability have been considered to be ideal candidates for electrodes of MICs.In this review,the advanced carbon materials directly as cathodes and anodes of MICs are systematically summarized.Then,the key structural/chemical factors including the structure engineering,porous characteristics,and heteroatom incorporation for improving electrochemical performance of carbon materials are highlighted.Additionally,the challenges and opportunities for future research on carbon materials in MICs are also proposed.

文摘Developing new types of rechargeable metal-ion batteries beyond lithium-ions,including alkaline ion(such as Na+,K+)and multivalent ion(such as Mg 2+,Zn 2+,Ca 2+and Al 3+)batteries,is progressing quickly towards large-scale energy storage systems.However,the major obstacle to their large-scale applications has been a lack of appropriate electrode materials with reversible metal ions insertion/extraction be-havior,resulting in inferior electrochemical performance.Here we develop a well-designed MoS_(2)/MoO_(2) hybrid nanosheets anchored on carbon cloth(MoS_(2)/MoO_(2)/CC)as electrode materials.This rational de-sign can effectively shorten ion diffusion distance,increase electric conductivity of the electrode,and buffer volume change.Benefiting from the synergistic effect of structural and compositional features,the MoS_(2)/MoO_(2)/CC electrode exhibits high initial reversible capacities(326 mA h g^(−1) at 0.1 A g^(−1) in magnesium-ion storage;1270 mA h g^(−1) at 0.1 A g^(−1) in sodium-ion storage),excellent rate capacities(57 mA h g^(−1) at 10 A g^(−1) in magnesium-ion storage;335 mA h g^(−1) at 5 A g^(−1) in sodium-ion storage)and long-term cycling stability(105 mA h g^(−1) after 600 cycle at 1 A g^(−1) in magnesium-ion storage;208 mA h g^(−1) after 600 cycles at 5 A g^(−1) in sodium-ion storage).We expect that the multi-engineering strategy will provide some valuable insights for the development of other advanced electrode materials for high-performance metal-ion batteries.

文摘Electrode materials are of decisive importance in determining the performance of electrochemical energy storage(EES)devices.Typically,the electrode materials are physically mixed with polymer binders and conductive additives,which are then loaded on the current collectors to function in real devices.Such a configuration inevitably reduces the content of active species and introduces quite some undesired interfaces that bring down the energy densities and power capabilities.One viable solution to address this issue is to construct self-supported electrodes where the active species,for example transition metal oxides(TMOs),are directly integrated with conductive substrates without polymer binders and conductive additives.In this review,the recent progress of self-supported TMO-based electrodes for EES devices including lithium-ion batteries(LIBs),sodium-ion batteries(SIBs),aluminum-ion batteries(AIBs),metal-air batteries,and supercapacitors(SCs),is discussed in great detail.The focused attention is firstly concentrated on their structural design and controllable synthesis.Then,the mechanism understanding of the enhanced electrochemical performance is presented.Finally,the challenges and prospects of self-supported TMO-based electrodes are summarized to end this review.

文摘Developing high-capacity and low-cost cathode materials for metal-ion rechargeable batteries is the mainstream trend and is also the key to providing breakthroughs in making high-energy rechargeable batteries.Vanadium has a variety of valence states and can form a variety of vanadate structures.As a typical positive electrode material,vanadate has abundant ion adsorption sites,a unique“pillar”framework,and a typical layered structure.Therefore,it has the advantages of high specific capacity and excellent rate performance,possessing the prospect of being a large-capacity energy storage material.In this review,we focus on applications of sodium vanadium oxides(NVO)in electrical energy storage(EES)devices and summarize sodium vanadate materials from three aspects,including crystal structure,electrochemical performance,and energy storage mechanism.The recent progress of NVO-based highperformance energy storage materials along with nanostructured design strategies was provided and discussed as well.This review is intended to serve as general guidance for researchers to develop desirable sodium vanadate materials.
