1Three dimensional porous frameworks for lithium dendrite suppression显示文摘Lithium metal is a promising anode material owing to its very low electrochemical potential and ultrahigh specific capacity.However,the growth of lithium dendrites could result in a short lifespan,low coulombic efficiency,and potential safety hazards during the progress of lithium plating/stripping.These factors drastically hinder its application in lithium metal batteries.This review focuses on the use of three dimensional(3D)porous host frameworks to improve Li plating/stripping behaviors,accommodate the change in volume,and suppress or block lithium dendrite growth.Various 3D porous frameworks,including the conductive carbon-based,metal-based,and lithiophilic inorganic-compound frameworks are introduced and summarized in detail.The particular functions,relative developments,and optimized strategies of various 3D porous frameworks for lithium deposition/dissolution behaviors are discussed.Moreover,the challenges and promising developments in the field of Li metal anodes will be discussed at the end of this review.Shuyan Ni Shuangshuang Tan Qinyou An Liqiang Mai 2020Journal of Energy Chemistry2020,29,5:11

4Low-strain TiP_(2)O_(7) withthree-dimensionalionchannelsas long-life and high-rate anode material for Mg-ion batteries显示文摘Rechargeable magnesium batteries are identified as a promising next-generation energy storage system,but their development is hindered by the anode−electrolyte−cathode incompatibilities and passivation of magnesium metal anode.To avoid or alleviate these problems,the exploitation of alternative anode materials is a promising choice.Herein,we present titanium pyrophosphate(TiP_(2)O_(7))as anode materials for magnesium-ion batteries(MIBs)and investigate the effect of the crystal phase on its magnesium storage performance.Compared with the me-tastable layered TiP_(2)O_(7),the thermodynamically stable cubic TiP_(2)O_(7) displays a better rate capability of 72 mAh g^(−1) at 5000 mA g^(−1).Moreover,cubic TiP_(2)O_(7) exhibits excellent cycling stability with the capacity of 60 mAh g^(−1) after 5000 cycles at 1000 mA g^(−1),which are better than pre-viously reported Ti-based anode materials for MIBs.In situ X-ray diffraction technology confirms the single-phase magnesiumion inter-calation/deintercalation reaction mechanism of cubic TiP_(2)O_(7) with a low volume change of 3.2%.In addition,the density functional theory calcu-lation results demonstrate that three-dimensional magnesiumion diffu-sion can be allowed in cubic TiP_(2)O_(7) with a low migration energy barrier of 0.62 eV.Our work demonstrates the promise of TiP_(2)O_(7) as high-rate and long-life anode materials for MIBs and may pave the way for further development of MIBs.Fangyu Xiong Yalong Jiang Li Cheng Ruohan Yu Shuangshuang Tan Chen Tang Chunli Zuo Qinyou An Yunlong Zhao Jean-Jacques Gaumet Liqiang Mai 2022Interdisciplinary Materials2022,1,1:3
5FeSe2 clusters with excellent cyclability and rate capabilityfor sodium-ion batteries显示文摘Sodium-ion batteries (SIBs) have great promise for sustainable and economicalenergy-storage applications. Nevertheless, it is a major challenge to developanode materials with high capacity, high rate capability, and excellent cyclingstability for them. In this study, FeSe2 clusters consisting of nanorods weresynthesized by a facile hydrothermal method, and their sodium-storage propertieswere investigated with different electrolytes. The FeSe2 clusters delivered highelectrochemical performance with an ether-based electrolyte in a voltage rangeof 0.5-2.9 V. A high discharge capacity of 515 mAh.g-1 was obtained after 400 cyclesat 1 A.g-1, with a high initial columbic efficiency of 97.4%. Even at an ultrahighrate of 35 A-g-1 a specific capacity of 128 mAh.g-1 was achieved. Using calculations,we revealed that the pseudocapacitance significantly contributed to the sodium-ionstorage, especially at high current rates, leading to a high rate capability. Thehigh comprehensive performance of the FeSe2 clusters makes them a promisinganode material for SIBs.Xiujuan Wei Chunjuan Tang Qinyou An Mengyu Yan Xuanpeng Wang Ping Hu Xinyin Cai Liqiang Mai 2017Nano Research2017,10,9:3
6Amine-assisted synthesis of FeS@N-C porous nanowires for highly reversible lithium storage显示文摘Iron sulfide is an attractive anode material for lithium-ion batteries (LIBs) due to its high specific capacity,environmental benignity,and abundant resources.However,its application is hindered by poor cyclability and rate performance,caused by a large volume variation and low conductivity.Herein,iron sulfide porous nanowires confined in an N-doped carbon matrix (FeS@N-C nanowires) are fabricated through a simple amine-assisted solvothermal reaction and subsequent calcination strategy.The as-obtained FeS@N-C nanowires,as an LIB anode,exhibit ultrahigh reversible capacity,superior rate capability,and long-term cycling performance.In particular,a high specific capacity of 1,061 mAh·g-1 can be achieved at 1 A·g-1 after 500 cycles.Most impressively,it exhibits a high specific capacity of 433 mAh·g-1 even at 5 A·g-1.The superior electrochemical performance is ascribed to the synergistic effect of the porous nanowire structure and the conductive N-doped carbon matrix.These results demonstrate that the synergistic strategy of combining porous nanowires with an N-doped carbon matrix holds great potential for energy storage.Xiujuan Wei Xin Tan Jiasheng Meng XuanpengWang Ping Hu Wei Yang Shuangshuang Tan Qinyou An Liqiang Mai 2018Nano Research2018,11,12:3
7Novel hollow Ni0.33Co0.67Se nanoprisms for high capacity lithium storage显示文摘In this work,homogeneous Ni0.33Co0.67Se hollow nanoprisms were synthesized successfully in virtue of Kirkendall effect.It is the first time for bimetallic Ni-Co compounds Ni0.33Co0.67Se to be used in lithium-ion batteries (LIBs).Impressively,the Ni0.33Co0.67Se hollow nanoprisms show superior specific capacity (1,575 mAh/g at the current density of 100 mA/g) and outstanding rate performance (850 mAh/g at 2,000 mA/g) as anode material for LIBs.This work proves the potential of bimetallic chalcogenide compounds as high performance anode materials for LIBs.Shaohua Zhu Cheng Chen Pan He Shuangshuang Tan Fangyu Xiong Ziang Liu Zhuo Peng Qinyou An Liqiang Mai 2019Nano Research2019,12,6:3
8Surface pseudocapacitance of mesoporous Mo_(3)N_(2) nanowire anode toward reversible high-rate sodium-ion storage显示文摘Sodium-ion storage devices are highly desirable for large-scale energy storage applications owing to the wide availability of sodium resources and low cost.Transition metal nitrides(TMNs)are promising anode materials for sodium-ion storage,while their detailed reaction mechanism remains unexplored.Herein,we synthesize the mesoporous Mo3N2 nanowires(Meso-Mo_(3)N_(2)-NWs).The sodium-ion storage mechanism of Mo3N2 is systematically investigated through in-situ XRD,ex-situ experimental characterizations and detailed kinetics analysis.Briefly,the Mo_(3)N_(2) undergoes a surface pseudocapacitive redox charge storage process.Benefiting from the rapid surface redox reaction,the Meso-Mo_(3)N_(2)-NWs anode delivers high specific capacity(282 m Ah g^(-1) at 0.1 A g^(-1)),excellent rate capability(87 m Ah g^(-1) at 16 A g^(-1))and long cycling stability(a capacity retention of 78.6%after 800 cycles at 1 A g^(-1)).The present work highlights that the surface pseudocapacitive sodium-ion storage mechanism enables to overcome the sluggish sodium-ion diffusion process,which opens a new direction to design and synthesize high-rate sodiumion storage materials.Yalong Jiang Jun Dong Shuangshuang Tan Qiulong Wei Fangyu Xiong Wei Yang Yuanhao Shen Qingxun Zhang Zi'ang Liu Qinyou An Liqiang Mai 2021Journal of Energy Chemistry2021,30,4:2
9Serrated lithium fluoride nanofibers-woven interlayer enables uniform lithium deposition for lithium-metal batteries显示文摘The uncontrollable formation of Li dendrites has become the biggest obstacle to the practical application of Li-metal anodes in high-energy rechargeable Li batteries.Herein,a unique LiF interlayer woven by millimeter-level,single-crystal and serrated LiF nanofibers(NFs)was designed to enable dendrite-free and highly efficient Li-metal deposition.This high-conductivity Li F interlayer can increase the Li^(+)transference number and induce the formation of’Li F–NFs-rich’solid–electrolyte interface(SEI).In the’Li F–NFs-rich’SEI,the ultra-long Li F nanofibers provide a continuously interfacial Li^(+)transport path.Moreover,the formed Li–LiF interface between Li-metal and SEI film renders low Li nucleation and high Li^(+)migration energy barriers,leading to uniform Li plating and stripping processes.As a result,steady charge–discharge in a Li//Li symmetrical cell for 1600 h under 4 m Ah cm^(-2)and 400 stable cycles under a high area capacity of 5.65 mAh cm^(-2)in a high-loading Li//rGO–S cell at 17.9 mA cm^(-2)could be achieved.The free-standing LiF–NFs interlayer exhibits superior advantages for commercial Li batteries and displays significant potential for expanding the applications in solid Li batteries.Shuangshuang Tan Yalong Jiang Shuyan Ni Hao Wang Fangyu Xiong Lianmeng Cui Xuelei Pan Chen Tang Yaoguang Rong Qinyou An Liqiang Mai 2022National Science Review2022,9,11:2
10Defect engineering in molybdenum-based electrode materials for energy storage显示文摘Molybdenum-based materials have stepped into the spotlight as promising electrodes for energy storage systems due to their abundant valence states,low cost,and high theoretical capacity.However,the performance of conventional molybdenum-based electrode materials has been limited by slow diffusion dynamics and deficient thermodynamics.Applying defect engineering to molybdenum-based electrode materials is a viable method for overcoming these intrinsic limitations to realize superior electrochemical performance for energy storage.Herein,we systematically review recent progress in defect engineering for molybdenum-based electrode materials,including vacancy modulation,doping engineering,topochemical substitution,and amorphization.In particular,the essential optimization mechanisms of defect engineering in molybdenum-based electrode materials are pre-sented:accelerating ion diffusion,enhancing electron transfer,adjusting potential,and maintaining structural stability.We also discuss the existing challenges and future objectives for defect engineering in molybdenum-based electrode materials to realize high-energy and high-power energy storage devices.Weixiao Wang Fangyu Xiong Shaohua Zhu Jinghui Chen Jun Xie Qinyou An 2022eScience2022,2,3:2

14Structural properties and electrochemical performance of different polymorphs of Nb_(2)O_(5) in magnesium-based batteries显示文摘The selection of the most suitable crystal structure for ions storage and the investigation of the corresponding reaction mechanism is still an ongoing challenge for the development of Mg-based batteries.In this article,high flexible graphene network supporting different crystal structures of Nb2 O5(TTNb_(2)O_(5)@rGO and T-Nb_(2)O_(5)@rGO) are successfully synthesized by a spray-drying-assisted approach.The three-dimensional graphene framework provides high conductivity and avoids the aggregation of Nb2 O5 nanoparticles.When employed as electrode materials for energy storage applications,TT-Nb_(2)O_(5) delivers a higher discharge capacity of 129.5 mAh g^(-1), about twice that of T-Nb_(2)O_(5) for Mg-storage,whereas,T-Nb_(2)O_(5) delivers a much higher capacity(162 mAh g^(-1)) compared with TT-Nb_(2)O_(5)(129 mAh g^(-1)) for Li-storage.Detailed investigations reveal the Mg intercalation mechanism and lower Mg^(2+) migration barriers,faster Mg^(2+) diffusion kinetics of TT-Nb_(2)O_(5) as cathode material for Mg-storage,and the faster Li+ diffusion kinetics,shorter diffusion distance of T-Nb_(2)O_(5) as cathode material for Li-storage.Our work demonstrates that exploring the proper crystal structure of Nb2 O5 for different ions storage is necessary.Cunyuan Pei Yameng Yin Xiaobin Liao Fangyu Xiong Qinyou An Mengda Jin Yan Zhao Liqiang Mai 2021Journal of Energy Chemistry2021,30,7:1
15Sulfur-linked carbonyl polymer as a robust organic cathode for rapid and durable aluminum batteries显示文摘Rechargeable aluminum batteries are believed as a promising next-generation energy-storage system due to abundant low-cost Al sources and high volumetric specific capacity.The Al-storage cathodes,however,are plagued by strong electrostatic interaction between host materials and carrier ions,leading to large overpotential and undesired cycling stability as well as sluggish ion diffusion kinetics.Herein,sulfur-linked carbonyl polymer based on perylene-3,4,9,10-tetracarboxylic dianhydride(PTCDA) as the cathode materials for ABs is proposed,which demonstrates a small voltage polarization(135 mV),a reversible capacity of 110 mAh g^(-1) at 100 mA g^(-1) even after 1200 cycles,and rapid Al-storage kinetics.Compared with PTCDA,the sulfide polymer possesses higher working voltage because of its lower LUMO energy level according to theoretical calculation.The ordered carbonyl active sites in sulfide polymer contribute to the maximized material utilization and rapid ion coordination and dissociation,resulting in superior rate capability.Besides,the bridged thioether bonds endow the polysulfide with robust and flexible structure,which inhibits the dissolution of active materials and improves cycling stability.This work implies the importance of ordered arrangement of redox active moieties for organic electrode,which provides the theoretical direction for the structural design of organic materials applied in multivalent-ion batteries.Liang Fang Limin Zhou Lianmeng Cui Peixin Jiao Qinyou An Kai Zhang 2021Journal of Energy Chemistry2021,30,12:1

17An adaptive hyper parameter tuning model for ship fuel consumption prediction under complex maritime environments显示文摘An accurate prediction of ship fuel consumption is critical for speed,trim,and voyage optimisation etc.While previous studies have focused on predicting ship fuel consumption with respect to a variety of factors,research on the impact of environmental factors on fuel consumption has been lacking.In addition,although recent research efforts have widely focused on machine learning methods to predict fuel consumption,studies on hyperparameter values that are suitable for these prediction models are limited.To compensate for this deficiency in existing literature,an adaptive hyperparameter tuning method is proposed,and the effects of maritime environmental factors on fuel consumption are taken into account.Through experimentation,the proposed adaptive hyperparameter tuning method was validated via artificial neural network(ANN),support vector regression(SVR),random forest(RF),and least absolute shrink-age and selection operator(Lasso).The hyperparameter tuning proportionally increased the amplitudes of the coefficients of determination(R 2)of these algorithms.The increase of the amplitude demonstrated the following trend,in the order of the largest increase to the lowest increase:ANN,Lasso,SVM,and RF.The rates of increase were between 0.0773%and 2.1653%.Furthermore,after the environmental factors were considered,the prediction accuracies of the ANN and Lasso increased;however,the opposite was observed for the SVR and RF.As such,we confirmed that the use of Bayesian optimisation for hyper-parameter tuning can effectively improve the fuel consumption prediction accuracy,and our proposed model can therefore serve as a significant reference for calculating fuel consumption.Tianrui Zhou Qinyou Hu Zhihui Hu Rong Zhen 2022Journal of Ocean Engineering and Science2022,7,3:0
18BmSE, a SINE family with 3′ ends of (ATTT) repeats in domesticated silkworm (Bombyx mori)显示文摘Short interspersed elements (SINEs), which are mainly composed of Bm1, are abundant in the domesticated silkworm. A 294 bp novel SINE family, designated as BmSE, was identified by mining the database of the complete Bombyx mori genome. A representational BmSE element is flanked by an 11 bp target site duplication sequence posterior poly (A) at the 3′ end and has the sequence motifs of an internal promoter of RNA polymerase III, which are similar to that of Bm1. The repetitive elements of BmSE are widely distributed in all 28 chromosomes of the genome and share the common (ATTT) repeats at the ends. GC-content distribution shows that BmSE tends to accumulate preferably in the region of higher AT content than that of Bm1. A high proportion of the BmSEs are mapped to the coding sequence introns, whereas several elements are also present in the UTR of some transcripts, indicating that BmSEs are indeed exonized with UTRs. Of the 615 identified structural variants (SVs) of BmSE among the 40 domesticated and wild silkworms, only 230 SVs were found in the domesticated silkworms, indicating that many recent SV events of BmSE occurred after domestication, which was probably due to its mobilization. Our analysis might assist in developing BmSE as a potential marker and in understanding the evolutionary roles of SINEs in the domesticated silkworm.Jinshan Xu Tie Liu Dong Li Ze Zhang Qinyou Xia Zeyang Zhou 2010Journal of Genetics and Genomics2010,37,2:0
19Porous yolk-shell structured Na_(3)(VO)_(2)(PO_(4))_(2)F microspheres with enhanced Na-ion storage properties显示文摘Na_(3)(VO)_(2)(PO_(4))_(2)F(NVPOF)has been considered as one potential candidate for sodium-ion batteries because of its high operating voltage and theoretical capacity.However,the poor intrinsic electronic conductivity significantly restricts its widespread application.In response to this drawback,we adopt the optimization strategy of tuning the morphology and structure to boost the electrical conductivity and mitigate the capacity fading.In this paper,NVPOF microspheres with unique porous yolk-shell structure were fabricated via a facile one-step solvothermal method for the first time.By monitoring the morphological evolution with time-dependent experiments,the self-sacrifice and Ostwald ripening mechanism from rough spheres to yolk-shell structure was revealed.Benefited from the favorable interwoven nanosheets shell,inner cavity and porous core structure,the resulting NVPOF electrode exhibits superior rate capability of 63 m A h g^(-1)at 20 C as well as outstanding long-cycling performance with the capacity retention up to 92.1%over 1000 cycles at 5 C.Yameng Yin Cunyuan Pei Fangyu Xiong Yi Pan Xiaoming Xu Bo Wen Qinyou An 2021Journal of Materials Science & Technology2021,,24:0
20Dynamic reconstruction of Ni-Zn alloy solid-electrolyte interface for highly stable Zn anode显示文摘Aqueous zinc ion batteries(AZIBs)are ideal candidates for large-scale battery storage,with a high theoretical specific capacity,ecological friendliness,and extremely low cost but are strongly hindered by zinc dendrite growth.Herein,Ni-Zn alloy is artificially constructed as a solid-electrolyte interface(SEI)for Zn anodes by electrodeposition and annealing.The Ni-Zn alloy layer acts as a dynamic shield at the electrode/electrolyte interface.Interestingly,the zinc atoms migrate out of the electrode body during zinc stripping while merging into the electrode body during the plating.In this way,the Ni-Zn alloy is able to guide the zinc deposition in the horizontal direction,thereby suppressing the formation of dendrite.Benefiting from those,the Ni-Zn alloy symmetric cell shows a greatly improved cycle life and is able to operate stably for 1,900 h at a current density of 0.5 mA·cm^(−2).The present study is a strategy for negative electrode protection of AZIBs.Qian Zhang Yuhang Dai Kangning Zhao Chengyi Zhang Ruihu Lu Jinghao Li Shuhan Jin Lei Zhang Qinyou An Liqiang Mai 2023Nano Research2023,16,9:0
