| 1 | A positive-temperature-coefficient electrode with thermal protection mechanism for rechargeable lithium batteries显示文摘A new positive-temperature-coefficient(PTC) material was prepared simply by blending of conductive Super P carbon black(CB) with insulating poly(methyl methacrylate)(PMMA) polymer matrix,which was empolyed as a coating layer on the aluminium foil substrate to fabricate a sandwiched Al/PTC/LiCoO2 cathode.The experimental results from cyclic voltammetry,charge-discharge measurements and impedance spectroscopy demonstrated that the PTC electrode has a normal electrochemical performance at ambient temperature,but shows an enormous increase in the resistance at the temperature range of 80?120℃.This PTC behavior greatly restrains the reaction current passing through the electrode at elevated temperatures,capable of acting as a self-actuating safety mechanism to prevent the battery from thermal runaway. | XIA Lan ZHU LiMin ZHANG HaiYan AI XinPing | 2012 | Chinese Science Bulletin2012，57，32： | 7 |
| 2 | Enabling an intrinsically safe and high-energy-density 4.5 V-class Li-ion battery with nonflammable electrolyte显示文摘Developing nonflammable electrolyte with a wide electrochemical window has become an urgent demand for high-energy-density and high-safe lithium-ion batteries(LIBs).Herein,a fluorinated nonflammable phosphate electrolyte is developed to construct a safe 4.5 V-class LIB(Si-SiC-C/0.35Li2MnO3-0.65LiNi0.5Mn0.5O2).The proposed fluorinated phosphate electrolyte,0.8 M LiPF6/tris(2,2,2-trifluoroethyl)phosphate(TFEP)+5 vol%fluoroethylene carbonate(FEC)+5 vol%vinylene carbonate(VC),is not only completely nonflammable but also exhibits excellent oxidative/reductive stability on 0.35Li2MnO30.65LiNi0.5Mn0.5O2 cathode and Si-SiC-C anode.The in situ differential electrochemical mass spectrometry and X-ray photoelectron spectroscopy proved that TFEP-based electrolyte does not decompose into gases but forms a high-quality electrode-electrolyte interface on cathode surface at high working potential.The 4.5 V-class LIBs using 0.8 M LiPF6 TFEP-based nonflammable electrolyte shed some light on potential application for high-safe and low-cost larger-scale energy storage. | Ziqi Zeng Xingwei Liu Xiaoyu Jiang Zhenjie Liu Zhangquan Peng Xiangming Feng Weihua Chen Dingguo Xia Xinping Ai Hanxi Yang Yuliang Cao | 2020 | InfoMat2020，2，5： | 6 |
| 3 | Mixed polyanion cathode materials:Toward stable and high-energy sodium-ion batteries显示文摘Sodium-ion batteries(SIBs)are considered as one of the most fascinating alternatives to lithium-ion batteries for grid-scale energy storage applications because of the low cost and wide abundance of sodium resources.Among various cathode materials,mixed polyanion compounds come into the spotlight as promising electrode materials due to their superior electrochemical properties,such as high working voltage,long cycling stability,and facile reaction kinetics.In this review,we summarize the recent development in the exploration of different mixed polyanion cathode materials for SIBs.We provide a comprehensive understanding of the structure-composition-performance relationship of mixed polyanion cathode materials together with the discussion of their sodium storage mechanisms.It is anticipated that further innovative works on the material design of advanced cathode materials for batteries can be inspired. | Along Zhao Yongjin Fang Xinping Ai Hanxi Yang Yuliang Cao | 2021 | Journal of Energy Chemistry2021，30，9： | 4 |
| 4 | High performance TiP_2O_7 nanoporous microsphere as anode material for aqueous lithium-ion batteries显示文摘This work developed a facile way to mass-produce a carbon-coated TiP_2O_7 nanoporous microsphere(TPO-NMS) as anode material for aqueous lithium-ion batteries via solid-phase synthesis combined with spray drying method. TiP_2O_7 shows great prospect as anode for aqueous rechargeable lithium-ion batteries(ALIBs) in view of its appropriate intercalation potential of-0.6 V(vs. SCE) before hydrogen evolution in aqueous electrolytes. The resulting sample presents the morphology of secondary microspheres(ca. 20 μm) aggregated by carbon-coated primary nanoparticles(100 nm), in which the primary nanoparticles with uniform carbon coating and sophisticated pore structure greatly improve its electrochemical performance. Consequently, TPONMS delivers a reversible capacity of 90 mA h/g at 0.1 A/g, and displays enhanced rate performance and good cycling stability with capacity retention of 90% after 500 cycles at 0.2 A/g. A full cell containing TPO-NMS anode and LiMn_2O_4 cathode delivers a specific energy density of 63 W h/kg calculated on the total mass of anode and cathode. It also shows good rate capacity with56% capacity maintained at 10 A/g rate(vs. 0.1 A/g), as well as long cycle life with the capacity retention of 82% after 1000 cycles at 0.5 A/g. | Yunping Wen Yao Liu Duan Bin Zhuo Wang Congxiao Wang Yuliang Cao Xinping Ai Yongyao Xia | 2019 | Science China Chemistry2019，62，1： | 3 |
| 5 | Understanding of the sodium storage mechanism in hard carbon anodes显示文摘Hard carbon has been regarded as the most promising anode material for sodiumion batteries(SIBs)due to its low cost,high reversible capacity,and low working potential.However,the uncertain sodium storage mechanism hinders the rational design and synthesis of high-performance hard carbon anode materials for practical SIBs.During the past decades,tremendous efforts have been put to stimulate the development of hard carbon materials.In this review,we discuss the recent progress of the study on the sodium storage mechanism of hard carbon anodes,and the effective strategies to improve their sodium storage performance have been summarized.It is anticipated that hard carbon anodes with high electrochemical properties will be inspired and fabricated for large-scale energy storage applications. | Xiaoyang Chen Changyu Liu Yongjin Fang Xinping Ai Faping Zhong Hanxi Yang Yuliang Cao | 2022 | Carbon Energy2022，4，6： | 3 |
| 6 | One Step Ball-Milling Synthesis of LiFePO_ 4 Nanoparticles as the Cathode Material of Li-Ion Batteries显示文摘A one-step synthetic method was used to synthesize Olivline LiFePO_ 4 powders by direct ball milling the stoichiometric mixture of Fe, Li_ 3 PO_ 4 , and FePO_ 4 powders. XRD and TEM measurements revealed that the as-prepared LiFePO_ 4 powder have a homogeneous Olivine structure and a uniform size distribution of ca.50 nm. Based on this material, a LiFePO_ 4 /C composite was prepared and used for the cathode material of Li-ion batteries. The charge-discharge experiments demonstrated that the LiFePO_ 4 /C composite material has a high capacity of 132 mAh/g at 0.1 C and a quite high-rate capability of 95 mAh/g at 1 C. This new ball-milling method may provide a completely green synthetic route for preparing the materials of this type cost-effectively and in large volume. | AI Xinping LI Hai LI Xiaoyan LIAO Qinli LIU Bingdong YANG Hanxi | 2006 | Wuhan University Journal of Natural Sciences2006，11，3： | 3 |
| 7 | A polyethylene microsphere-coated separator with rapid thermal shutdown function for lithium-ion batteries显示文摘Thermal runaway is the main factor contributing to the unsafe behaviors of lithium-ion batteries(LIBs)in practical applications.The application of separators for the thermal shutdown has been proven as an effective approach to protecting LIBs from thermal runaway.In this work,we developed a thermal shutdown separator by coating a thin layer of low-density polyethylene microspheres(PM)onto a commercial porous polypropylene(PP)membrane and investigated the thermal response behaviors of the as-prepared PM/PP separator in LIBs.The structural and thermal analysis results revealed that the coated PM layer had a porous structure,which facilitated the occurrence of normal charge-discharge reactions at ambient temperature,although it could melt completely and fuse together within very short time periods:3 s at 110℃and 1 s at 120℃,to block off the pores of the PP substrate,thereby cutting off the ion transportation between the electrodes and interrupting the battery reaction.Consequently,the PM/PP separator exhibits very similar electrochemical performance to that of a conventional separator at ambient temperature.However,it performs a rapid thermal shutdown at an elevated temperature of^110℃,thus controlling the temperature rise and maintaining the cell in a safe status.Due to its synthetic simplicity and low cost,this separator shows promise for possible application in building safe LIBs. | Chongrong Zhang Hui Li Shixuan Wang Yuliang Cao Hanxi Yang Xinping Ai Faping Zhong | 2020 | Journal of Energy Chemistry2020，29，5： | 2 |
| 8 | Real-time emergency route generating algorithm in tunnel显示文摘As part of the digital mine system, a real time emergency route generating algorithm for a large scale metal mine is studied. The tunnel is abstracted and mathematically described by the center line model. A series of definitions are made and the center lines are regularized. In order to improve the quality of the final routes, a center line dataset preprocessing is done according to the factors including the slope threshold and the tunnel closed state information, etc. While in preprocessing, the mineshaft and shaft with the steep slope are excluded implicitly. The interface is preserved for point-like objects (e.g. blowers), directions (e.g. wind direction of blowers) and so on. The final path finding algorithm is optimized by the filter operation that the calculation is only performed at the endpoints and hub points, which can further reduce computing data amount. In our experiment, 3 368 nodes out of 22 401 nodes are selected as key nodes, therefore, the data processing amount of the algorithm is reduced to 1/7 and the routes can be found in real time. The algorithm is implemented and integrated into the final digital mine system. | FANG Yuan-min1, CHEN Jie1, AI Chun-long2, ZHANG Chun-liang2, ZHOU Shi-yong2, FU Xia-jiang2, GU De-mao2 1.
