| 3 | Electrolyte design strategies towards long-term Zn metal anode for rechargeable batteries显示文摘Rechargeable Zinc(Zn)batteries exhibit great potentials as alternative energy storage devices due to their high safety,low cost,and environmental friendliness.However,the long-standing issues of low Coulombic efficiency(CE)and poor cycle stability of Zn anode,derived from dendrite,H_(2)evolution,and passivation are directly related to their thermodynamic instability in aqueous electrolyte,severely shorten the battery's cycle life.Recently reported electrolyte design strategies,which have made great progress to address Zn metal anode problems,are summarized into two categories,that is,aqueous electrolytes about cation-water interaction controlling and interface adjusting,and novel types of electrolytes towards less water,non-aqueous solvents,even no solvents.The final section shows the brief comparisons,including failure mechanisms of electrolyte exhaustion and short circuit for aqueous and nonaqueous electrolyte based full cells respectively,and possible perspectives for future research. | Ming Xu Jiahang Chen Yang Zhang Bareera Raza Chunyan Lai Jiulin Wang | 2022 | Journal of Energy Chemistry2022，31，10： | 0 |

| 5 | Controlled Synthesis of Porous Carbon Nanostructures with Tunable Closed Mesopores via a Silica-Assisted Coassembly Strategy显示文摘Controllable fabrication of mesoporous carbon nanoparticles(MCNs)with tunable pore structures is of great interest,due to the remarkable effect of pore structure on electrochemical performance of the materials.However,it has remained a major challenge.Here,we demonstrate the controlled synthesis of MCNs with tunable closed pore structures via a silica-assisted coassembly strategy,which employs polystyrene-block-poly(ethylene oxide)diblock copolymers as soft template,phenolic resol and tetraethyl orthosilicate as carbon and silica precursors,respectively.Through simply varying the sequential cross-linking of the silica and carbon precursors or the copolymer composition,novel MCNs with alluring spherical,hollow-hoop-structured,or yolk-shell-like closed mesopores are tunably prepared.In particular,serving as cathode materials of lithium-sulfur batteries,the resultant silica-hybridized MCNs with the exceptional hollow-hoop mesopores and a moderate sulfur-loading content of 46 wt%exhibit top-level electrochemical performance.This study opens an avenue for tunable construction of mesoporous particles with closed pores and provides clues for the effect of pore geometry on the electrochemical performance of porous cathode materials for lithium-sulfur batteries. | Binbin Guo Chen Li Haoran Wu Jiahang Chen Jiulin Wang Hao Wei Yiyong Mai | 2021 | CCS Chemistry2021，3，5： | 0 |

| 7 | Post lithium-sulfur battery era:challenges and opportunities towards practical application显示文摘Lithium-sulfur(Li-S)batteries have been regarded as a promising next-generation energy storage system owing to the high theoretical energy density and natural abundance of sulfur.Abundant fundamental researches have pushed the flourishing development on electrochemical behaviors in recent 20 years.It is time to evolve into post-Li-S battery era with the pursuit towards practical application.During the landmark leap,numerous new challenges appear under harsh conditions,such as high sulfur loading,low cathode density,lean electrolyte and limited lithium reservoir.Herein,we summarize the considerable parameters of pouch Li-S cells and review the pioneering studies focused on the cathode structure,conversion kinetics,electrode interphase and battery safety.The interwoven relationship of these key points is concluded and discussed,which provides guidance to future researches aiming to safe and long-lifespan Li-S batteries with high energy density. | Jiahang Chen Yang Zhang Jun Yang Yanna Nuli Jiulin Wang | 2024 | Science China Chemistry2024，67，1： | 0 |
| 8 | A crosslinking hydrogel binder for high-sulfur content S@pPAN cathode in rechargeable lithium batteries显示文摘High-energy density lithium-sulfur(Li-S) batteries have received intensive attention as promising energy storage system.Among diverse sulfur-based cathodes,sulfurized pyrolyzed poly(acrylonitrile)(S@pPAN)cathode delivered superior electrochemical performance.However,the sulfur content of S@pPAN is relatively low(<50 wt%),which significantly limits the energy density.Herein,a hydrogel SA-Cu binder was proposed with a crosslinking network constructed by Cu^(2+) ions.The introduction of Cu^(2+) ions enabled excellent electrochemical behaviors of S@pPAN cathode even with high sulfur content of 52.6 wt% via chemical interaction with sulfur and polysulfide.Moreover,a favorable cathode interphase was formed containing electrochemically active and conductive CuSx.S@pPAN/SA-Cu exhibited a high sulfur utilization of 85.3%,long cycling stability over 1000 cycles and remarkable capacity of 1200 mAh g_(s)^(-1) even at10 C.Furthermore,ascribed to the improved electrode structure,high-loading electrode(sulfur loading:4 mg cm^(-2)) displayed stable cycling with areal capacity of 5.26 mAh cm^(-2)(1315 mAh g_(s)^(-1)) after 40 cycles.This study provides new directions to prepare high-sulfur content and high-loading S@pPAN cathode for higher energy density. | Huanhuan Yuan Cheng Guo Jiahang Chen Huichao Lu Jun Yang Yanna Nuli Jiulin Wang | 2021 | Journal of Energy Chemistry2021，30，9： | 0 |
| 9 | Crosslinked polyacrylonitrile precursor for S@pPAN composite cathode materials for rechargeable lithium batteries显示文摘S@pPAN has become promising cathode materials in rechargeable batteries due to its high compressed density,low E/S ratio,no polysulfide dissolution,no self-discharge,and stable cycling.However,it is a big challenge to enhance its sulfur content which determines its practical specific capacity.Herein,we prepare crosslinked PAN as precursor,leading to effective enhancement of sulfur content up to 55 wt%and a reversible specific capacity of 838 mAh g _(composites)^(-1) at 0.2C.Because of the microporous structure and high specific area,crosslinked PAN provides more space to accommodate sulfur molecule and improve the interfacial reaction of S@pPAN as well.This work provides a promising direction to design S@pPAN for lithium sulfur batteries with high energy density. | Jingyu Lei Huichao Lu Jiahang Chen Jun Yang Yanna Nuli Jiulin Wang | 2022 | Journal of Energy Chemistry2022，31，2： | 0 |
| 10 | Electrolyte solvation chemistry to construct an anion-tuned interphase for stable high-temperature lithium metal batteries显示文摘Lithium metal batteries are regarded as promising alternative next-generation energy storage systems.However,the unstable anode interphase results in dendrite growth and irreversible lithium consumption with low Coulombic efficiency(CE).Herein,we rationally design a Li^(+)coordination structure via electrolyte solvation chemistry.Nitrate anions are aggregated in the solvation sheath,even at low concentration in a solvent with moderate solvation ability,which promotes Li^(+)desolvation and constructs a nitrate anion-tuned interphase.Meanwhile,a high-donor-number solvent is introduced as an additive to strongly coordinate with Li^(+),which accelerates the ion-transfer kinetics and rate performance.This not only results in micro-sized lithium deposition and a high CE of 99.5%over 3500 h,but also enables superior anode stability even under 50%depth plating/stripping and with a lean electrolyte of 3 g Ah^(-1)at 50℃.A lithium-sulfur battery exhibits a prolonged lifespan of 2000 cycles with an average CE of 100%.A full battery using 1x excess lithium exhibits a high capacity near 1600 mAh g S^(-1)for 100 cycles without capacity loss.Moreover,a 0.55 Ah pouch cell delivers a reversible energy density of 423 Wh kg^(-1)based on these electrodes and electrolyte. | Jiahang Chen Yang Zhang Huichao Lu Juan Ding Xingchao Wang Yudai Huang Huiyang Ma Jiulin Wang | 2023 | eScience2023，3，4： | 0 |
| 11 | Geochemical characteristics of produced fluids from CBM wells and their indicative significance for gas accumulation in Daning-Jixian block,Ordos Basin显示文摘The Daning-Jixian block,the eastern edge of the Ordos Basin,is one of the most potential areas for CO_(2)geological storage,enhanced coalbed methane recovery(ECBM)exploration and production in China in recent decades.The ionic composition and total dissolved solids(TDS)of the produced water,coal organic matter maturity,molecular composition and carbon isotope characteristics of the produced gas were utilized to analyze the hydrogeological condition,CBM generation and migration characteristics in this area.The CBM enrichment patterns and the geological impacts on gas well production characteristics were revealed.The optimal area for CBM development and CO_(2)geological storage in the study area were also proposed.Dominated by the Xueguan reverse fault zone,the hydraulic unit in this area can be divided into two parts(i.e.,the recharge-runoff zone in the east and the weak runoff-stagnation zone in the west).The thermogenic gas is dominating CBM genesis in this area.Secondary biogenic gas replenishment is only distributed in the eastern margin area,where theδ13C1 value is less than the thermal simulation results as an influence of hydrodynamic fractionation.Finally,two models of CBM formation and accumulation were proposed,1)thermogenic CBM migrated by hydrodynamic and resorbed for preservation at impermeable fault boundaries;2)thermogenic CBM trapped by fault and accumulated by hydrodynamic in slope zone.The gas production performance,generally increased from east to west,is mainly dominated by hydrogeological conditions.Generally,the west side of the fault zone is the enrichment and high-yield area for ECBM development and CO_(2)geological storage in the study area. | Taotao YAN Chao YANG Shuai ZHENG Yadong BAI Wei CHEN Yanfei LIU Wenguang TIAN Shasha SUN Shangwen JIN Jiahang WANG Zhenxing LIU Huifang YAO | 2023 | Frontiers of Earth Science2023，17，3： | 0 |
