Growing market demand from portable electronics to electric automobiles boosts the development of lithium-ion batteries(LIBs)with high energy density and rate performance.However,strong solvation effect between lithium ions(Li^(+))and solvent molecules in common electrolytes limits the mobility of Li^(+)ions in electrolytes.Consequently,anions dominate the charge conduction in electrolytes,and in most cases,the value of Li^(+)transference number(T_(+))is between 0.2 and 0.4.A low T_(+)will aggravate concentration polarization in the process of charging and discharging,especially at high rate,which not only increases the overpotential but also intensifies side reactions,along with uneven deposition of lithium(Li)and the growth of lithium dendrites when lithium metal is used as anode.In this review,promising strategies to improve T_(+)in liquid electrolytes would be summarized.The migration of Li^(+)ions is affected directly by the types and concentration of lithium salts,solvents,and additives in bulk electrolytes.Besides,Li^(+)ions will pass through the separator and solid electrolyte interphase(SEI)when transferring between anodes and cathodes.With this in mind,we will classify and summarize threads of enhancing T_(+)from five aspects:lithium salts,solvents,additives,separators,and SEI based on different mechanisms,including covalently bonding,desolvation effect,Lewis acid-base interaction,electrostatic interaction,pore sieving,and supramolecular interaction.We believe this review will present a systematic understanding and summary on T_(+)and point out some feasible threads to enhance battery performance by enhancing T_(+).

Polymerization is a valid strategy to solve the dissolution issue of organic electrode materials in aprotic electrolytes.However,conventional polymers usually with amorphous structures and morphology’s influence on electrochemistry have rarely been studied.Herein,a hollow tubular poly phenyl pyrene-4,5,9,10-tetraone(T-PPh-PTO)organic cathode material was designed and synthesized based on the concentration-gradient of the precursor(PTO-Br2)and asymmetrical internal diffusion during the reaction.The unique hollow structure endowed T-PPh-PTO with a short Li+diffusion path accompanied by a high diffusion Li+coefficient(D≈10−8 cm^(2)·s^(−1)).Thus,T-PPh-PTO presented a capacitance-dominated redox pseudocapacitance action with an outstanding rate performance(173 mAh·g^(−1)at 2 A·g^(−1))and high cycle stability(capacity retention ratio is 91.7%after 2,000 cycles).Our study leads to further developments in designing unique organic structures for energy storage.

Given the energy demands of the electromobility market,the energy density and safety of lithium batteries(LBs)need to be improved,whereas its cost needs to be decreased.For the enhanced performance and decreased cost,more suitable electrode and electrolyte materials should be developed based on the improved understanding of the degradation mechanisms and structure–performance correlation in the LB system.Thus,various in situ characterization technologies have been developed during the past decades,providing abundant guidelines on the design of electrode and electrolyte materials.Here we first review the progress of in situ characterization of LBs and emphasize the feature of the multi-model coupling of different characterization techniques.Then,we systematically discuss how in situ characterization technologies reveal the electrochemical processes and fundamental mechanisms of different electrode systems based on representative electrode materials and electrolyte components.Finally,we discuss the current challenges,future opportunities,and possible directions to promote in situ characterization technologies for further improvement of the battery performance.

lithium cobalt oxide(LiCoO_(2),LCO)dominates in 3C(computer,communication,and consumer)electronics-based batteries with the merits of extraordinary volumetric and gravimetric energy density,high-voltage plateau,and facile synthesis.Currently,the demand for lightweight and longer standby smart portable electronic products drives the development of the upper cut-off voltage of LCO-based batteries to further improve the energy density.However,several challenges,including irreversible structural transformation,surface degradation,cobalt dissolution and oxygen evolution along with detrimental side reactions with the electrolyte remain with charging to a high cut-off voltage(>4.2 V vs.Li/Li+),resulting in rapid capacity decay and safety issues.Based on the degradation mechanisms and latest advances of the high-voltage LCO,this review summarizes modification strategies in view of the LCO structure,artificial interface design and electrolytes optimization.Meanwhile,many advanced characterization and monitoring techniques utilized to clarify the structural and interfacial evolution of LCO during charge/discharge process are critically emphasized.Moreover,the perspectives in terms of integrating multiple modification strategies,applying gel and solid-state electrolytes,optimizing the recovery process and scalable production are presented.

lithium-metal batteries with high energy/power densities have significant applications in electronics,electric vehicles,and stationary power plants.However,the unstable lithium-metal-anode/electrolyte interface has induced insufficient cycle life and safety issues.To improve the cycle life and safety,understanding the formation of the solid electrolyte interphase(SEI)and growth of lithium dendrites near the anode/electrolyte interface,regulating the electrodeposition/electrostripping processes of Li^(+),and developing multiple approaches for protecting the lithium-metal surface and SEI layer are crucial and necessary.This paper comprehensively reviews the research progress in SEI and lithium dendrite growth in terms of their classical electrochemical lithium plating/stripping processes,interface interaction/nucleation processes,anode geometric evolution,fundamental electrolyte reduction mechanisms,and effects on battery performance.Some important aspects,such as charge transfer,the local current distribution,solvation,desolvation,ion diffusion through the interface,inhibition of dendrites by the SEI,additives,models for dendrite formation,heterogeneous nucleation,asymmetric processes during stripping/plating,the host matrix,and in situ nucleation characterization,are also analyzed based on experimental observations and theoretical calculations.Several technical challenges in improving SEI properties and reducing lithium dendrite growth are analyzed.Furthermore,possible future research directions for overcoming the challenges are also proposed to facilitate further research and development toward practical applications.

Solid-state batteries have become a frontrunner in humankind’s pursuit of safe and stable energy storage systems with high energy and power density.Electrolyte materials,currently,seem to be the Achilles’heel of solid-state batteries due to the slow kinetics and poor interfacial wetting.Combining the merits of solid inorganic electrolytes(SIEs)and solid polymer electrolytes(SPEs),inorganic/polymer hybrid electrolytes(IPHEs)integrate improved ionic conductivity,great interfacial compatibility,wide electrochemical stability window,and high mechanical toughness and flexibility in one material,having become a sought-after pathway to high-performance all-solid-state lithium batteries.Herein,we present a comprehensive overview of recent progress in IPHEs,including the awareness of ion migration fundamentals,advanced architectural design for better electrochemical performance,and a perspective on unconquered challenges and potential research directions.This review is expected to provide a guidance for designing IPHEs for next-generation lithium batteries,with special emphasis on developing high-voltage-tolerance polymer electrolytes to enable higher energy density and three-dimensional(3D)continuous ion transport highways to achieve faster charging and discharging.

Ionic liquids(ILs)have been deemed as promising electrolyte materials for building safer and highly-performing rechargeable lithium batteries,owing to their negligible volatility,low-flammability,and high thermal stability,etc.The profound structural designability of IL cations and anions allows relatively facile regulations of their key physical(e.g.,viscosities,and ionic conductivities)and electrochemical(e.g.,anodic,and cathodic stabilities)properties,and therefore fulfills the critical requirements stipulated by various battery configurations.In this review,a historical overview on the development of ILs for nonaqueous electrolytes is provided,and the correlations between chemical structures and the basic properties of ILs are discussed.Furthermore,the key achievements in the field of IL-based electrolytes are scrutinized,including liquid electrolytes,polymer electrolytes,and composite polymer electrolytes.Based on literature reports and our previous work in this field,possible strategies to improve the performance of IL-based electrolytes and their rechargeable batteries are discussed.The present work not only provides the status quo in the development of IL-based electrolytes but also inspires the structural design of ILs for other kinds of rechargeable batteries(e.g.,sodium,potassium,zinc batteries).

Anions in the electrolyte are usually ignored in conventional"rocking-chair"batteries because only cationic de-/intercalation is considered.An ingenious scheme combining LiMn_(0.7)Fe_(0.3)PO_(4)(LMFP@C)and graphite as a hybrid cathode for lithium-ion batteries(LIBs)is elaborately designed in order to exploit the potential value of anions for battery performance.The hybrid cathode has a higher conductivity and energy density than any of the individual components,allowing for the co-utilization of cations and an-ions through the de-/intercalation of Li^(+)and PF_(6)−over a wide voltage range.The optimal compound with a weight mix ratio of LMFP@C:graphite=5:1 can deliver the highest specific capacity of nearly 140 mA h/g at 0.1 C and the highest voltage plateau of around 4.95 V by adjusting the appropriate mixing ratio.In addition,cyclic voltammetry was used to investigate the electrode kinetics of Li^(+)and PF_(6)−dif-fusion in the hybrid compound at various scan rates.In situ X-ray diffraction is also performed to further demonstrate the structural evolution of the hybrid cathode during the charge/discharge process.

Rechargeable lithium batteries have been widely regarded as a revolutionary technology to store renewable energy sources and extensively researched in the recent several decades.As an indispensable part of lithium batteries,the evolution of anode materials has significantly promoted the development of lithium batteries.However,since conventional lithium batteries with graphite anodes cannot meet the ever-increasing demands in different application scenarios(such as electric vehicles and large-scale power supplies)which require high energy/power density and long cycle life,various improvement strategies and alternative anode materials have been exploited for better electrochemical performance.In this review,we detailedly introduced the characteristics and challenges of four representative anode materials for rechargeable lithium batteries,including graphite,Li_(4)Ti_(5)O_(12),silicon,and lithium metal.And some of the latest advances are summarized,which mainly contain the modification strategies of anode materials and partially involve the optimization of electrode/electrolyte interface.Finally,we make the conclusive comments and perspectives,and draw a development timeline on the four anode materials.This review aims to offer a good primer for newcomers in the lithium battery field and benefit the structure and material design of anodes for advanced rechargeable lithium batteries in the future.
