3Porous-hollow nanorods constructed from alternate intercalation of carbon and MoS2 monolayers for lithium and sodium storage显示文摘Weak ion diffusion and electron transport due to limited interlayer spacing and poor electrical conductivity have been identified as critical roadbacks for fast and abundant energy storage of both MoS2-based lithium ion batteries (LIBs) and sodium ion batteries (SIBs). In this work, MoS2 porous-hollow nanorods (MoS2/m-C800) have been designed and synthesized via an annealing-followed chemistry-intercalated strategy to solve the two issues. They are uniformly assembled from ultrathin MoS2 nanosheets, deviated to the rod-axis direction, with expanded interlayer spacing due to alternate intercalation of N-doped carbon monolayers between the adjacent MoS2 monolayers. Electrochemical studies of the MoS2/m-C800 sample, as an anode of LIBs, demonstrate that the superstructure can deliver a reversible discharge capacity of 1,170 mAh·g^-1 after 100 cycles at 0.2 A·g^-1 and maintain a reversible capacity of 951 mAh·g^-1 at 1.25 A·g^-1 after 350 cycles. While for SIBs, the superstructure also delivers a reversible discharge capacity of 350 mAh·g^-1 at 0.5 A-g-1 after 500 cycles and exhibits superior rate capacity of 238 mAh·g^-1 at 15 A·g^-1 .The excellent electrochemical performance is closely related with the hierarchical superstructures, including expanded interlayer spacing, alternate intercalation of carbon monolayers and mesoporous feature, which effectively reduce ion diffusion barrier, shorten ion diffusion paths and improve electrical conductivity.Laiying Jing Gang Lian Junru Wang Mingwen Zhao Xizheng Liu Qilong Wang Deliang Cui Ching-Ping Wong 2019Nano Research2019,12,8:3

5High performance Zn-I_(2)battery with acetonitrile electrolyte working at low temperature显示文摘Large scale applications of metal-iodine batteries working at sub-zero degree have been challenged by the limited capacity and performance degradation.Herein,we firstly propose a Zn-I_(2)battery working at low temperature with a carbon composite material/iodine(CCM-I_(2))cathode,a Zn anode and an environmentally tolerable Zn(ClO4)2-ACN electrolyte.The CCM framework with hierarchical porous structure endows a powerful iodine-anchoring to overcome undesirable dissolution of iodine in organic electrolyte,and the Zn(ClO4)2-ACN electrolyte with low freezing point and high ionic conductivity enhances the low temperature performance.The synergies enable an efficiently reversible conversion of Zn-I_(2)battery even at-40℃.Therefore,the resultant Zn-I_(2)battery delivers a high specific capacity of 200 mAh·g^(-1),which is fairly approximate to the theoretical capacity of I_(2)(211 mAh·g^(-1))and a superior cycling stability with minimal capacity fading of 0.00043%per cycle over 7,000 times under 2C at-20℃.Furthermore,even at-40℃,this Zn-I_(2)battery still exhibits a good capacity retention of 68.7%compared to the capacity at 25℃ and a rapid capacity-recover ability with elevating temperature change.Our results distinctly indicate this Zn-I_(2)battery can be 1competent for the practical application under low temperature operation.Chunlai Song Zongshuai Gong Chong Bai Fengshi Cai Zhihao Yuan Xizheng Liu 2022Nano Research2022,15,4:1

9In situ preparation of gel polymer electrolyte for lithium batteries: Progress and perspectives显示文摘The practical applications of Li-ion batteries(LIBs)are challenged by their safety concerns when using liquid electrolytes(LEs).Solid-state gel polymer electrolytes(GPEs)can address this challenge and have drawn increased attention recently.Normally,GPEs are prepared separately and then assembled into cells,which undoubtedly result in dissatisfactory solid/solid interfacial compatibility and low ionic conductivity.Fortunately,in situ GPEs are proposed to address the above challenges and simplify the preparation process.Typically,LE precursor is injected into the cells and gradually transformed into a quasisolid gel state under the conditions of thermal or chemical initiators.Consequently,the obtained in situ GPEs could fully infiltrate the electrode and better interface contact of gel electrolyte/electrode is thus inherited.In this review,the authors focus on the in situ GPEs used in lithium batteries(LBs),and summarize recent progress of the design,synthesis,and applications of in situ GPEs.Based on the different ways of triggering polymerization,there are mainly three methods:thermochemical gelation,polymerization by additional chemical initiators,and cross-linking initiated by Li O bond.Composite GPEs based on in situ solidification method are introduced as a promising strategy to improve the electrochemical performances.Finally,up-to-date research progresses are discussed,and perspectives are provided on the development and challenges of in situ GPEs to meet the requirements for their practical applications in LBs.Chao Ma Wenfeng Cui Xizheng Liu Yi Ding Yonggang Wang 2022InfoMat2022,4,2:1

12Effect of Anngro Adjuvant under the Condition of Pesticide Reduction显示文摘[Objective] The paper was to study the effects of Anngro adjuvant under the condition of pesticide reduction.[Method] With rice as the research object,a novel botanical adjuvant Anngro was mixed with 75% trifloxystrobin tebuconazole WDG and 35% chlorantraniliprole WDG at half dosage,and sprayed to control striped rice borer(Chilo suppressalis),rice sheath blight(Rhizoctonia solani) and false smut(Ustilaginoidea oryzae).The rice yield of pesticide reduction was compared with that of conventional application,to explore the cost-saving,effect-increasing,green and environment-friendly diseases and insect pests control technology of rice in Honghu area.[Result] The combined application of Anngro and three dosage forms of pesticides at half dosage had synergistic effect on the control of striped rice borer compared with conventional application at normal dosage,and the effect was improved by 2.67%.The control effects of the two application methods on rice sheath blight and false smut were equiva-lent.There were no significant differences in rice yield and other economic traits.[Conclusion] Anngro can be used as an effective adjuvant in Honghu area,which increases the prevention and control effect of rice diseases and insect pests,reduces agricultural non-point source pollution,and improves ecological environment.It can be used as a pesticide synergistic adjuvant for further demonstration and promotion.Pubing Zheng Xizheng Liu Wei Zhou Zhixin Zhen Shiwei Li 2021Plant Diseases and Pests2021,12,4:0
13Reversible Low Temperature Li-Storage in Liquid Metal Based Anodes via a Co-Solvent Strategy显示文摘Main observation and conclusion The application of lithium-ion batteries in cold climates has been hindered due to the decline in performance at low temperatures.The increased de-solvation energy and formation of Li dendrites at the anode surface emerge as the major challenges,which rely on the development of stable anode and compatible electrolytes.Herein,a self-healing GaInSn liquid metal(LM)based electrode coupled with a multi-solvent electrolyte is proposed toward reversible Li-storage at low temperatures.By using methyl butyrate(MB)as a co-solvent in 1 mol·L^(–1)LiTFSI of ethylene carbonate and diethyl carbonate,the electrolyte viscosity decreases from 52.07 to 13.75 mPa·s,while the ionic conductivity increases from 1.38 to 3.44 mS·cm^(–1)at–20°C.Moreover,the Li/MXene@LM cells can display a discharge capacity of 500 mAh·g^(–1),with capacity retention of 78%at–20°C after 120 cycles.It is disclosed that a uniform LiF-rich solid electrolyte interface(SEI)layer on the anode is formed upon the addition of MB,which promotes the desolvation of Li ions at the interface of electrode/electrolyte especially at low temperatures.These results prove that MB as the co-solvent is well compatible with LM based anodes and holds great potential for the exploration of low-temperature energy devices.Mengdi Zhang Xiaofeng Lei Yang Lv Xizheng Liu Yi Ding 2021Chinese Journal of Chemistry2021,39,10:0
14Wide-temperature rechargeable Li metal batteries enabled by an in-situ fabricated composite gel electrolyte with a hierarchical structure显示文摘Lithium metal bateries(LMBs)are well recognized as promising next-generation high energy density batteries,but the uncontrollable Li dendrites growth and the volatilization/gas production of electrolytes,which become extremely worse at low and high temperatures,restrict their practical utilizations.In this work,a hierarchically structured polymerized gel electrolyte(HGE),which was composed of an inorganic(Li_(x)Ga_(86) In_(14) alloy and Licl salt)/organic(polymerized tetrahydrofuran(THF)hybrid layer and the bulk polymerized THF electrolyte,was proposed to achieve a steady performance of LMBs over a wide temperature range of-20-55℃.The HGE fabrication can be completed within ssembled ells with a simultaneously occurring replacement-polymerizationalloying reaction,which helps decrease the interfacial resistance and enhance the stability and ion diffusion under both low and high temperatures.The use of THF with low polarity also ensures high ion conductivity under low temperatures.With such HGE,the Li symmetric cell showed low overpotential under 10 mA/cm^(2) with a capac.ity of 10 mAh/cm^(2) over a 1200 h cycling,and the fullcell coupled with Li_(4)Ti_(5)O_(12) demonstrated high capacity retention over 5000 cycles at room temperature.Besides,the symmetric cells showed low overpotentials of 12 mV at 55℃ and 80 mV at-20℃ at 2 mA/cm^(2) after a 1000 h cyeling,and the full cell revealed the high capacity retention of 93.5%at 55℃ and 88.8%at-20℃ after 1500 cycles under a high current density of 1000 mA/g.This work shows a hierarchically structured polymerized electrolyte design for advanced Li batteries workable under broad temperatures.Chao Ma Xizheng Liu Hui Geng Xiaoshu Qu Wei Lv Yi Ding 2022Fundamental Research2022,2,4:0

16Characterization and evaluation of a femtosecond laser-induced osseointegration and an anti-inflammatory structure generated on a titanium alloy显示文摘Cell–material interactions during early osseointegration of the bone–implant interface are critical and involve crosstalk between osteoblasts and osteoclasts.The surface properties of titanium implants also play a critical role in cell–material interactions.In this study,femtosecond laser treatment and sandblasting were used to alter the surface morphology,roughness and wettability of a titanium alloy.Osteoblasts and osteoclasts were then cultured on the resulting titanium alloy disks.Four disk groups were tested:a polished titanium alloy(pTi)control;a hydrophilic micro-dislocation titanium alloy(sandblasted Ti(STi));a hydrophobic nano-mastoid Ti alloy(femtosecond laser-treated Ti(FTi));and a hydrophilic hierarchical hybrid micro-/nanostructured Ti alloy[femtosecond laser-treated and sandblasted Ti(FSTi)].The titanium surface treated by the femtosecond laser and sandblasting showed higher biomineralization activity and lower cytotoxicity in simulated body fluid and lactate dehydrogenase assays.Compared to the control surface,the multifunctional titanium surface induced a better cellular response in terms of proliferation,differentiation,mineralization and collagen secretion.Further investigation of macrophage polarization revealed that increased anti-inflammatory factor secretion and decreased proinflammatory factor secretion occurred in the early response of macrophages.Based on the above results,the synergistic effect of the surface properties produced an excellent cellular response at the bone–implant interface,which was mainly reflected by the promotion of early ossteointegration andmacrophage polarization.Yang Liu Zhongying Rui Wei Cheng Licheng Song Yunqiang Xu Ruixin Li Xizheng Zhang 2021Regenerative Biomaterials2021,8,2:0
