Tunability of optical performance is one of the key technologies for adaptive optoelectronic applications,such as camouflage clothing, displays, and infrared shielding. High-precision spectral tunability is of great importance for some special applications with on-demand adaptability but remains challenging. Here we demonstrate a galvanostatic control strategy to achieve this goal, relying on the finding of the quantitative correlation between optical properties and electrochemical reactions within materials. An electrochromic electro-optical efficiency index is established to optically fingerprint and precisely identify electrochemical redox reactions in the electrochromic device. Consequently, the charge-transfer process during galvanostatic electrochemical reaction can be quantitatively regulated, permitting precise control over the final optical performance and on-demand adaptability of electrochromic devices as evidenced by an ultralow deviation of <3.0%. These findings not only provide opportunities for future adaptive optoelectronic applications with strict demand on precise spectral tunability but also will promote in situ quantitative research in a wide range of spectroelectrochemistry, electrochemical energy storage, electrocatalysis, and material chemistry.

Solid-state lithium-metal batteries(SLMBs)have been regarded as one of the most promising next-generation devices because of their potential high safety,high energy density,and simple packing procedure.However,the practical applications of SLMBs are restricted by a series of static and dynamic interfacial issues,including poor interfacial contact,(electro-)chemical incompatibility,dynamic Li dendrite penetration,etc.In recent years,considerable attempts have been made to obtain mechanistic insight into interfacial failures and to develop possible strategies towards excellent interfacial properties for SLMBs.The static and dynamic failure mechanisms at interfaces between solid electrolytes(SEs)and electrodes are comprehensively summarized,and design strategies involving interfacial modification,electrode/SE engineering,and the monolithic construction of SLMBs are discussed in detail.Finally,possible research methodologies such as theoretical calcu-lations,advanced characterization techniques,and versatile design strategies are provided to tackle these interfacial problems.

Owing to the advantages of high operating voltage,environmental benignity,and low cost,potassium-based dual-ion batteries(KDIBs)have been considered as a potential candidate for large-scale energy storage.However,KDIBs generally suffer from poor cycling performance and unsatisfied capacity,and inactive components of conductive agents,binders,and current collector further lower their overall capacity.Herein,we prepare coral-like carbon nanowres(CCNWs)doped with nitrogen as a binder-free anode material for K^(+)-ion storage,in which the unique coral-like porous nanostructure and amorphous/short-range-ordered composite feature are conducive to enhancing the structural stability,to facilitating the ion transfer and to boosting the full utilization of active sites during potassiation/de-potassiation process.As a result,the CCNW anode possesses a hybrid K^(+)-storage mechanism of diffusive behavior and capacitive adsorption,and stably delivers a high capacity of 276 mAh g^(-1)at 50 mA g^(-1),good rate capability up to 2 A g^(-1),and long-term cycling stability with 93%capacity retention after 2000 cycles at 1 A g^(-1).Further,assembling this CCNW anode with an environmentally benign expanded graphite(EG)cathode yields a proof-of-concept KDIB,which shows a high specific capacity of 134.4 mAh g^(-1)at 100 mA g^(-1),excellent rate capability of 106.5 mAh g^(-1)at 1 A g^(-1),and long-term cycling stability over 1000 cycles with negligible capacity loss.This study provides a feasible approach to developing high-performance anodes for potassium-based energy storage devices.

The rapid development of human society has led to much increased consumption of energy,which results in global energy shortage as well as serious environmental concerns due to the use of non-sustainable fossil fuels.For example,the heavy relay on the use of coal and oil leads to carbon emission which is a major factor for global warming and climate change.Developing green and sustainable energy paths becomes more urgent than ever.In this regard,energy sources like sunshine,wind,and water are important to build a clean and sustainable future.For example,one could generate electricity from sun by solar cell devices.Later,such electricity can be stored either in the form of charges by batteries or supercapacitors,or stored in the form of chemicals by electrochemical catalysis conversion,which can be transported over a long distance or stored for a long time for end use.The efficiency of these new energy technologies and devices including photovoltaic,energy storage,and energy conversion,is key which determines whether they can be largescale implemented.High-performance materials play central rules in determining the efficiency of these technologies and therefore largely influence the use of these clean energy technologies and paths toward global mission of carbon neutrality.

Bi is a promising anode material for potassium-ion batteries(PIBs)due to its high theoretical capacity.However,severe pulverization upon cycling limits its practical applications.In this work,we propose a new approach of using metastable alloys with Bi elements.Metastable Bi:Co and Bi:Fe alloys nanodots@carbon anode materials(Bi:Co and Bi:Fe@C)are synthesized for the first time via simple annealing of their metal-organic frameworks(MOF)precursors.These prepared materials are demonstrated as ideal hosts for high-rate K-ion storage.Bi_(0.85)Co_(0.15)@C and Bi_(0.83)Fe_(0.17)@C electrodes respectively deliver superior 178 and 253 mAh·g^(−1)at 20 A·g^(−1),as well as stable cycling performance at 2 A·g^(−1).Ex situ scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD),and transmission electron microscopy(TEM)studies on Bi:Co@C indicate that the elemental Co separates out during the initial potassiation and stands during the following discharge/charge cycles.In situ formed Co precipitates can act as(1)“conductive binders”as well as(2)“separators”to prevent the severe aggregation of adjacent active elemental Bi nanoparticles and(3)accelerate the potassiation/de-potassiation kinetics in elemental Bi precipitates after initial discharge/charge cycles.This work could inspire the development of metal-type anodes.

In conventional ethylene carbonate(EC)/propylene carbonate(PC)electrolyte,sodium metal reacts spontaneously and deleteriously with solvent molecules.This significantly limits the practical feasibility of high-voltage sodium metal batteries based on Na metal chemistry.Herein,we present a sodium metal alloy strategy via introducing NaIn and Na_(2)In phases in a Na/In/C composite,aiming at boosting Na ion deposition stability in the common EC/PC electrolyte.Symmetric cells with Na/In/C electrodes achieve an impressive long-term cycling capability at 1 mA cm^(-2)(>870 h)and 5 mA cm^(-2)(>560 h),respectively,with a capacity of 1 mAh cm^(-2).In situ optical microscopy clearly unravels a stable Na ion dynamic deposition process on the Na/In/C composite electrode surface,attributing to a dendrite-free and smooth morphology.Furthermore,theoretical simulations reveal intrinsic mechanism for the reversible Na ion deposition behavior with the composite Na/In/C electrode.Upon pairing with a highvoltage NaVPOF cathode,Na/In/C anode illustrates a better suitability in SMB s.This work promises an alternative alloying strategy for enhancing Na metal interfacial stability in the common EC/PC electrolyte for their future applications.

Employing cathode materials with multiple redox couples and electrolytes with efficient cation transport kinetics are two effective approaches to improving the electrochemical performance of batteries.In this work,for the first time,we present a design strategy of simultaneously realizing reversible cationic and anionic redox chemistries as well as selective anion/cation transport in the viologen-based COFs(BAVCOF:X,coordinated anions of X=Cl^(-),Br^(-),I^(-),and ClO_(4)^(-))for high-performance Na-ion cathodes.Besides the cationic redox of viologen segments,the different redox activities of anions effectively tune the total capacities of the COFs.Meanwhile,electrochemical analysis and ab-initial molecular dynamics(AIMD)calculation illustrate that the anion/cation transport kinetics of electrolytes caged in the COFs'channels can be selectively tuned by the coordinated anions.As a result,combining high-potential Br-/Br_(2)redox couple,cationic redox of viologen segments,and enhanced Na+transport kinetics,the BAV-COF:Brdemonstrates stable performance with energy densities of 358.7 and 145.2 Wh kg^(-1)at power densities of 116.5 and 2124.1 W kg^(-1),respectively.This study offers new insight into the fabrication of organic cathodes with anionic redox and the advantages of COFs electrode materials in anion/cation transport selectivity for energy storage applications.

Sodium-based dual-ion batteries(Na-DIBs) show a promising potential for large-scale energy storage applications due to the merits of environmental friendliness and low cost.However,Na-DIBs are generally subject to poor rate capability and cycling stability for the lack of suitable anodes to accommodate large Na~+ ions.Herein,we propose a molecular grafting strategy to in situ synthesize tin pyrophosphate nanodots implanted in N-doped carbon matrix(SnP2O7@N-C),which exhibits a high fraction of active SnP2O7up to 95.6 wt% and a low content of N-doped carbon(4.4 wt%) as the conductive framework.As a result,this anode delivers a high specific capacity~400 mAh g-1at 0.1 A g-1,excellent rate capability up to 5.0 A g-1and excellent cycling stability with a capacity retention of 92% after 1200 cycles under a current density of1.5 A g-1.Further,pairing this anode with an environmentally friendly KS6 graphite cathode yields a SnP~2 O7@N-C||KS6 Na-DIB,exhibiting an excellent rate capability up to 30 C,good fast-charge/slow-discharge performance and long-term cycling life with a capacity retention of~96% after 1000 cycles at 20 C.This study provides a feasible strategy to develop high-performance anodes with high-fraction active materials for Na-based energy storage applications.
