| 1 | A composite PEO electrolyte with amide-based polymer matrix for suppressing lithium dendrite growth in all-solid-state lithium battery显示文摘The lithium dendrite growth is still a serious challenge and impeding the realistic applications of all-solid-state lithium batteries.In view of the amide containing sediment layer can be stable on lithium/cathodes,a composite polymer electrolyte with amide-based matrix is in-situ built on porous electrodes.With the introduction of amide,the polymer electrolyte presents excellent ability to inhibit lithium dendrite growth and makes the Li/Li symmetric battery stably work for 500 h with a good ionic conductivity of 4.25×10^(-5)S/cm at 40℃.The solid electrolyte also shows a wide electrochemical stable window and good interface contact with the porous cathode.Utilizing this composite polymer electrolyte,the all-solid-state Li/LiFePO_(4) battery shows an initial discharge capacity of 146.5 mA h/g at 0.1 C under 40℃ and remains 81.4%in 100 cycles.The polymer electrolyte also can present better properties after modification.These results demonstrate that the presented PA-based composite polymer electrolyte could be served as a good electrolyte candidate for all-solid-state lithium-ion batteries. | Menghan Ge Xiaoyu Zhou Yinping Qin Yang Liu Jingjing Zhou Xiaolei Wang Bingkun Guo | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 2 | A bi-functional strategy involving surface coating and subsurface gradient co-doping for enhanced cycle stability of LiCoO_(2) at 4.6 V显示文摘Layered LiCoO_(2)(LCO)acts as a dominant cathode material for lithium-ion batteries(LIBs)in 3C products because of its high compacted density and volumetric energy density.Although improving the high cutoff voltage is an effective strategy to increase its capacity,such behavior would trigger rapid capacity decay due to the surface or/and structure degradation.Herein,we propose a bi-functional surface strategy involving constructing a robust spinel-like phase coating layer with great integrity and compatibility to LiCoO_(2) and modulating crystal lattice by anion and cation gradient co-doping at the subsurface.As a result,the modified LiCoO_(2)(AFM-LCO)shows a capacity retention of 80.9%after 500 cycles between 3.0and 4.6 V.The Al,F,Mg enriched spinel-like phase coating layer serves as a robust physical barrier to effectively inhibit the undesired side reactions between the electrolyte and the cathode.Meanwhile,the Al,F,Mg gradient co-doping significantly enhances the surficial structure stability,suppresses Co dissolution and oxygen release,providing a stable path for Li-ions mobility all through the long-term cycles.Thus,the surface bi-functional strategy is an effective method to synergistically improve the electrochemical performances of LCO at a high cut-off voltage of 4.6 V. | Yun He Xiaoliang Ding Tao Cheng Hongyu Cheng Meng Liu Zhijie Feng Yijia Huang Menghan Ge Yingchun Lyu Bingkun Guo | 2023 | Journal of Energy Chemistry2023，，2： | 0 |
| 3 | Exploration of Sponge System Design in Wetland Parks Based on Rainwater and Flood Control: A Case Study of Southern Anhui Province显示文摘Based on the background that wetland resources in China are under threat and urgently need to be protected,a series of rainwater and flood problems caused by urban construction is analyzed comprehensively,and the design and planning methods of wetland parks in response to rainwater and flood disasters caused by floods and heavy rainfall are explored.Southern Anhui with complex and variable terrain and frequent rainfall and flood disasters is selected as the research area,with Xuanzhou District of Xuancheng City as the main research object.The relationship between municipal drainage of urban park and water conservancy drainage is investigated from different sample selection,design samples,and design flow rates.Based on literature review and model building methods,an urban storm flood model suitable for typical wetland parks in southern Anhui is constructed after processing the survey data using Arc GIS,SWMM(storm water management model).On this basis,a methodology and principles for designing a sponge system of wetland park based on rainwater and flood control are proposed,including technical measures such as rainwater collection,retention,and purification.This paper provides certain research results in design schemes,effect evaluations,ecological and social benefits,and useful suggestions and solutions for urban stormwater management and resilience development. | CAO Menghan GE Juan HU Yueyue ZHANG Yanwen LI Yinan | 2023 | Journal of Landscape Research2023，15，6： | 0 |
| 4 | Transformation Design of Old Parks Based on Behavior Psychology: A Case Study of Hefei Xiaoyaojin Park显示文摘City park undertakes the function of urban core green island. Hefei Xiaoyaojin Park providesa leisure and entertainment place for Hefei citizens. Although it has been continuously transformed andupgraded, there are still many places to be improved. Through behavior observation and questionnaire,the usage and satisfaction evaluation of tourists in Xiaoyaojin Park were obtained, and the transformationdesign of Xiaoyaojin Park was analyzed from the perspective of behavior psychology by analyzing thebehavior of tourists in different zones of Xiaoyaojin. Based on the premise of exploring the behaviorof tourists in different spaces, a city park environment that meets the needs of tourists can be created bypromoting the cultural context of the Three Kingdoms, improving the plant landscape and infrastructureof the site, optimizing the spatial function, and exploring the park design and transformation strategy that ismore in line with the needs of people, in order to provide new ideas for the future landscape transformationof Xiaoyaojin park, and offer reference suggestions for the future transformation design of old city parks. | GE Juan CAO Menghan CHEN Jiaxin HU Yueyue LI Quanjun LI Yinan | 2023 | Journal of Landscape Research2023，15，5： | 0 |
| 5 | Application of Shrub Landscape on Campus from the Perspective of Ornamental Characteristics of Plants显示文摘In the campus greening design,the shrub height is generally consistent with people’s horizontal line of sight,which plays a significant role in people’s visual focus.From the perspective of ornamental characteristics of plants,the application of shrub landscape is explored in a campus environment.Based on the analysis of the selection,arrangement and maintenance of shrub plants in campus gardens,the application of shrub landscape on campus was evaluated comprehensively from the theoretical analysis of plant ornamental characteristics and campus shrub landscape.Based on the research background of the problems existing in the application of shrub landscape on campus,this paper first collected and sorted out the relevant theories extensively,and then conducted in-depth research on the relevant theories by using analysis methods such as literature data,field investigation and questionnaire survey.The results will provide a theoretical guidance and practical advocacy for campus garden planning and design,and help to create a livable and comfortable campus environment.It is hoped that the results will have some references for future campus shrub landscape and play a certain promoting role. | HU Yueyue CAO Menghan GE Juan LI Quanjun CHEN Long LI Yanfei | 2023 | Journal of Landscape Research2023，15，4： | 0 |
