This is especially relevant for stationary applications, where the size and weight of battery are less important. The working efficiency and capacity of these batteries are mainly dependent on the anode, cathode, and electrolyte. The anode,which is one of these components, is by far the most important part of the rechargeable battery.Because of its characteristics and its structure, the anode has a tremendous impact on the overall performance of the battery as a whole. Keeping the above in view, in this review we critically reviewed the different types of anodes and their performances studied to date in LIBs and SIBs. The review article is divided into three main sections, namely:(i) intercalation reaction-based anode materials;(ii) alloying reaction-based anode materials;and(iii) conversion reaction-based anode materials, which are further classified into a number of subsections based on the type of material used. In each main section, we have discussed the merits and challenges faced by their particular system. Afterward, a brief summary of the review has been discussed. Finally, the road ahead for better application of Li/Na-ion batteries is discussed, which seems to mainly depend on exploring the innovative materials as anode and on the inoperando characterization of the existing materials for making them more capable in terms of application in rechargeable batteries.展开更多

文摘The outstanding performance of O3-type NaNi_(1/3)Fe_(1/3)Mn_(1/3)O_(2)(NFM111)at both high and low temperatures coupled with its impressive specific capacity makes it an excellent cathode material for sodium-ion batteries.However,its poor cycling,owing to highpressure phase transitions,is one of its disadvantages.In this study,Cu/Ti was introduced into NFM111 cathode material using a solidphase method.Through both theoretically and experimentally,this study found that Cu doping provides a higher redox potential in NFM111,improving its reversible capacity and charge compensation process.The introduction of Ti would enhance the cycling stability of the material,smooth its charge and discharge curves,and suppress its high-voltage phase transitions.Accordingly,the NaNi_(0.27)Fe_(0.28)Mn_(0.33)Cu_(0.05)Ti_(0.06)O_(2)sample used in the study exhibited a remarkable rate performance of 142.97 mAh·g^(-1)at 0.1 C(2.0-4.2 V)and an excellent capacity retention of 72.81%after 300 cycles at 1C(1C=150 mA·g^(-1)).
文摘Since lithium-ion batteries(LIBs) have been substantially researched in recent years, they now possess exceptional energy and power densities, making them the most suited energy storage technology for use in developed and developing industries like stationary storage and electric cars, etc. Concerns about the cost and availability of lithium have prompted research into alternatives, such as sodium-ion batteries(SIBs), which use sodium instead of lithium as the charge carrier. This is especially relevant for stationary applications, where the size and weight of battery are less important. The working efficiency and capacity of these batteries are mainly dependent on the anode, cathode, and electrolyte. The anode,which is one of these components, is by far the most important part of the rechargeable battery.Because of its characteristics and its structure, the anode has a tremendous impact on the overall performance of the battery as a whole. Keeping the above in view, in this review we critically reviewed the different types of anodes and their performances studied to date in LIBs and SIBs. The review article is divided into three main sections, namely:(i) intercalation reaction-based anode materials;(ii) alloying reaction-based anode materials;and(iii) conversion reaction-based anode materials, which are further classified into a number of subsections based on the type of material used. In each main section, we have discussed the merits and challenges faced by their particular system. Afterward, a brief summary of the review has been discussed. Finally, the road ahead for better application of Li/Na-ion batteries is discussed, which seems to mainly depend on exploring the innovative materials as anode and on the inoperando characterization of the existing materials for making them more capable in terms of application in rechargeable batteries.

文摘The urgent demand for renewable energy solutions,propelled by the global energy crisis and environmental concerns,has spurred the creation of innovative materials for solar thermal storage.Photothermal phase change materials(PTPCMs)represent a novel type of composite phase change material(PCM)aimed at improving thermal storage efficiency by incorporating photothermal materials into traditional PCMs and encapsulating them within porous structures.Various porous encapsulation materials have been studied,including porous carbon,expanded graphite,and ceramics,but issues like brittleness hinder their practical use.To overcome these limitations,flexible PTPCMs using organic porous polymers—like foams,hydrogels,and porous wood—have emerged,offering high porosity and lightweight characteristics.This review examines recent advancements in the preparation of PTPCMs based on porous polymer supports through techniques like impregnation and in situ polymerization,assessing the impact of different porous polymer materials on PCM performance and clarifying the mechanisms of photothermal conversion and heat storage.Subsequently,the most recent advancements in the applications of porous polymer-based PTPCMs are systematically summarized,and future research challenges and possible solutions are discussed.This review aims to foster awareness about the potential of PTPCMs in promoting environmentally friendly energy practices and catalyzing further research in this promising field.

文摘Lignocellulosic materials(LCMs),abundant biomass residues,pose significant environmental challenges when improperly disposed of.LCMs,such as sugarcane bagasse,rice straw,saw dust and agricultural residues,are abun-dant but often burned,contributing to air pollution and greenhouse gas emissions.This review explores the potential of transforming these materials into high-value carbon nanomaterials(CNMs).We explore the potential of transforming these materials into high-value CNMs.By employing techniques like carbonization and activa-tion,LCMs can be converted into various CNMs,including carbon nanotubes(CNTs),graphene(G),graphene oxide(GO),carbon quantum dots(CQDs),nanodiamonds(NDs),fullerenes(F),carbon nanofibers(CNFs),and others.Hybridizing different carbon allotropes further enhances their properties.CNMs derived from cellulose,lignin,and hemicellulose exhibit promising applications in diversefields.For instance,CNTs can be used in energy storage devices like batteries and supercapacitors due to their exceptional electrical conductivity and mechanical strength.Additionally,CNTs can be incorporated into recycled paper as afire retardant additive,enhancing itsflame resistance.G,renowned for its high surface area and excellent electrical conductivity,finds applications in electronics,sensors,catalysis,and water treatment,where it can be used to adsorb heavy metal ions.CQDs,owing to their unique optical properties,are used in bioimaging,drug delivery,and optoelectronic devices.By harnessing the potential of LCMs,we can not only mitigate environmental concerns but also contri-bute to a sustainable future.Continued research is essential to optimize synthesis methods,explore novel applica-tions,and unlock the full potential of these versatile materials.
