| 1 | Effect of surface area and heteroatom of porous carbon materials on electrochemical capacitance in aqueous and organic electrolytes显示文摘A series of porous carbon materials with wide range of specific surface areas and different heteroatom contents had been prepared using polyaniline as carbon precursor and KOH as an activating agent. Effect of surface area and heteroatom of porous carbon materials on specific capacitance was investigated thoroughly in two typical aqueous KOH and organic 1-butyl-3- methylimidazolium tetrafluoroborate/acetonitirle electrolytes. The different trends of capacitance performance were observed in these two electrolytes. Electrochemical analyses suggested that the presence of faradaic interactions on heteroatom-enriched carbon materials in organic environment is less significant than that observed in aqueous electrolytes. Thus, in aqueous electrolyte, a balance between surface area and heteroatom content of activated porous carbon would be found to develop a supercapacitor with high energy density. In organic electrolyte, the capacitance performance of porous carbon is strongly dependent on the surface area. The results may be useful for the design of porous carbon-based supercapacitor with the desired capacitive performance in aqueous and organic electrolytes. | WANG RuTao LANG JunWei YAN XingBin | 2014 | Science China Chemistry2014，57，11： | 4 |

| 4 | A high-performance potassium-ion capacitor based on a porous carbon cathode originated from the Aldol reaction product显示文摘Potassium-ion capacitors(KICs) emerge as a promising substitute for the well-developed lithium-ion capacitors(LICs),however,the energy density of KICs is below expectations because of lacking a suitable electrical double-layer positive electrode.Using chemical activation of the Aldol reaction product of acetone with KOH,we synthesized a porous ca rbon with a Brunauer-Emmett-Teller surface area of up to 2947 m2/g and a narrow pore size distribution ranging from 1 nm to 3 nm.Half-cell(versus potassium metal) test demonstrates that this porous carbon has high capacitive performance in K+ based organic electrolytes.Furthermore,a novel KIC fabricated by this porous carbon as the cathode,yields high values of energy density and power density.The processes used to make this porous carbon are readily low-cost to fabricate metal-ion capacitors. | Xu Yu Mingjie Shao Xuemei Yang Chongxing Li Tong Li Danyu Li Rutao Wang Longwei Yin | 2020 | Chinese Chemical Letters2020，31，9： | 1 |

| 6 | Scalable synthesis of macroscopic porous carbon sheet anode for potassium-ion capacitor显示文摘Carbon materials hold the great promise for application in energy storage devices owing to their low cost, high thermal/chemical stability, and high electrical conductivity. However, it remains challenging to synthesize high-performance carbon electrodes in a simple, scalable and sustainable way. Here, we report a facile method for scalable synthesis of porous carbon anode by using cheap and easily accessible zeolitic imidazolate framework-8 as a template and polyvinylpyrrolidone as an additional carbon source. The obtained porous carbon shows the macroscopic sheet-like morphology, which has the highly disordered structure, expanded interlayer spacing, abundant pore structure, and nitrogen doping properties. This porous carbon anode is demonstrated to have the excellent K^(+) charge storage properties in specific capacity, rate capability, and cycling stability. A potassium-ion capacitor assembled by using this porous carbon as the anode, delivers a maximum energy density of 85.12 Wh/kg and power density of 11860 W/kg as well as long cycle life exceeding 3000 cycles. This represents a critical advance in the design of low cost and scalable carbon material for applications in energy storage devices. | Yuying Qin Yuhao Xie Han Zhao Chunyan Zhu Tong Li Shuxian Zhang Rutao Wang Yuanchang Shi Longwei Yin | 2022 | Chinese Chemical Letters2022，33，3： | 1 |
| 7 | Progress and perspectives on two-dimensional silicon anodes for lithium-ion batteries显示文摘Silicon(Si)anodes with extremely high theoretical capacities are considered indispensable for next-generation high-energy lithium-ion batteries(LIBs).However,several intractable problems,including pulverization,poor electrical contact,and continuous side reactions caused by the large volume change of Si during lithia-tion/delithiation,lead to a short cycle life and poor rate capability,thus hindering the commercial use of Si anodes in LIBs.Two-dimensional(2D)Si with a unique graphene-like structure has a short ion diffusion path-way,small volume change during lithiation,and efficient redox site utilization,making it more promising than bulk Si or Si with other versatile structures for use in LIBs.Theoretical analysis demonstrated that the low energy barrier on the surface of 2D Si accelerates the transport of Li+.However,the issues surrounding 2D Si,includ-ing the tedious and user-unfriendly synthesis,ease of restacking,and atmospheric sensitivity,limit its practical applications,which are discussed in this review.Furthermore,possible solutions to these remaining challenges and new directions are provided,with the aim of designing practical and high-performance 2D Si anodes for next-generation LIBs. | Han Zhao Fan Yang Chongxing Li Tong Li Shuxian Zhang Chengxiang Wang Zhiwei Zhang Rutao Wang | 2023 | ChemPhysMater2023，2，1： | 1 |
| 8 | Advanced all-solid-state lithium-selenium batteries enabled by selenium-nitrogen doped hierarchic meso-microporous carbon nanospheres composite cathode显示文摘Selenium,an element belonging to the same group in the periodic table as sulfur,has a high electronic conductivity(1×10^(-5)S/cm)and a high volumetric energy density(3253 mA h/cm^(3)),which is a prospective cathode material for high-energy all-solid-state rechargeable batteries.However,its wide use is hindered by large volume expansion and low utilization rate.In this work,Se-infused nitrogen-doped hierarchical meso-microporous carbon composites(Se/NHPC)are prepared by a melt-diffusion process.Amorphous Se is uniformly dispersed in meso-micropores of NHPC with a high mass loading of 81%.All-solid-state Li-Se batteries fabricated by using Se/NHPC as the cathode,a Li-In alloy as the anode,and Li_(6)PS_(5)Cl as the solid-state electrolyte,deliver a highly reversible capacity of 621 m Ah/g(92%of theoretical capacity),a good rate capability and a high capacity retention value of 80.9%after 100 cycles.It is found that the capacity decay of Se cathode is mainly related to the interfacial degradation and the separation of Se from the carbon substrate,as suggested by the continuous increase of interfacial resistance and the structural transformation from amorphous Senchains to Se8rings initial discharge/charge cycle and then to the trigonally crystalline Se chains structure after the long-term cycles. | Chongxing Li Renbo Liu Shuxian Zhang Qingyu Li Cong Wang Zhiwei Zhang Chengxiang Wang Longwei Yin Rutao Wang | 2023 | Chinese Chemical Letters2023，34，9： | 0 |
| 9 | Ordered Macroporous MoS_(2)-Carbon Composite with Fast and Robust Sodium Storage Properties to Solve the Issue of Kinetics Mismatch of Sodium-Ion Capacitors显示文摘Metal-ion capacitors(including Li^(+),Na^(+),and K^(+))effectively combine a battery negative electrode capable of reversibly intercalating metal cations,together with an electrical double-layer positive electrode.However,such novel cell design has a birth defect,namely kinetics mismatch between sluggish negative electrode and fast positive electrode,thus limiting the energy-power performance.Herein,we design a MoS_(2)-carbon composite anode with the ordered macroporous architecture and interlayer-expanded feature,exhibiting the fast and reversible Na^(+)redox processes.This kinetically favored anode is coupled with a homemade activated carbon cathode that allows for the excellent electrochemical performance of sodiumion capacitor with respect to large specific capacity,high-rate capability,and robust cycling.Through quantification of the potential swings of anode and cathode via a three-electrode Swagelok cell,we for the first time observe the abnormal variation law of potential swings and thus directly providing the evidence that the kinetics gap has been filled up by this kinetically favored anode.Our results represent a crucial step toward understanding the key issues of kinetics mismatch for hybrid cell,thus propelling the development of design of kinetically favored anode materials for high-performance metalion capacitors. | Weiqing Yu Chunyan Zhu Rutao Wang Jianchao Chen Qingyuan Liu Shuxian Zhang Shoubao Zhang Jinfeng Sun Longwei Yin | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
| 10 | Novel biomarkers identifying hypertrophic cardiomyopathy and its obstructive variant based on targeted amino acid metabolomics显示文摘Background:Hypertrophic cardiomyopathy(HCM)is an underdiagnosed genetic heart disease worldwide.The management and prognosis of obstructive HCM(HOCM)and non-obstructive HCM(HNCM)are quite different,but it also remains challenging to discriminate these two subtypes.HCM is characterized by dysmetabolism,and myocardial amino acid(AA)metabolism is robustly changed.The present study aimed to delineate plasma AA and derivatives profiles,and identify potential biomarkers for HCM.Methods:Plasma samples from 166 participants,including 57 cases of HOCM,52 cases of HNCM,and 57 normal controls(NCs),who first visited the International Cooperation Center for HCM,Xijing Hospital between December 2019 and September 2020,were collected and analyzed by high-performance liquid chromatography-mass spectrometry based on targeted AA metabolomics.Three separate classification algorithms,including random forest,support vector machine,and logistic regression,were applied for the identification of specific AA and derivatives compositions for HCM and the development of screening models to discriminate HCM from NC as well as HOCM from HNCM.Results:The univariate analysis showed that the serine,glycine,proline,citrulline,glutamine,cystine,creatinine,cysteine,choline,and aminoadipic acid levels in the HCM group were significantly different from those in the NC group.Four AAs and derivatives(Panel A;proline,glycine,cysteine,and choline)were screened out by multiple feature selection algorithms for discriminating HCM patients from NCs.The receiver operating characteristic(ROC)analysis in Panel A yielded an area under the ROC curve(AUC)of 0.83(0.75-0.91)in the training set and 0.79(0.65-0.94)in the validation set.Moreover,among 10 AAs and derivatives(arginine,phenylalanine,tyrosine,proline,alanine,asparagine,creatine,tryptophan,ornithine,and choline)with statistical significance between HOCM and HNCM,3 AAs(Panel B;arginine,proline,and ornithine)were selected to differentiate the two subgroups.The AUC values in the training and validation sets for Panel B were 0.83(0.74-0.93)and 0.82(0.66-0.98),respectively.Conclusions:The plasma AA and derivatives profiles were distinct between the HCM and NC groups.Based on the differential profiles,the two established screening models have potential value in assisting HCM screening and identifying whether it is obstructive. | Lanyan Guo Bo Wang Fuyang Zhang Chao Gao Guangyu Hu Mengyao Zhou Rutao Wang Hang Zhao Wenjun Yan Ling Zhang Zhiling Ma Weiping Yang Xiong Guo Chong Huang Zhe Cui Fangfang Sun Dandan Song Liwen Liu Ling Tao | 2022 | Chinese Medical Journal2022，135，16： | 0 |
