| 1 | 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 |
| 2 | 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 |
| 3 | 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 |
| 4 | 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 |
| 5 | Low temperature hydrothermal synthesis and electrochemical performances of LiFePO_4 microspheres as a cathode material for lithium-ion batteries显示文摘Mesoporous LiFePO4 microspheres were simply synthesized by a low temperature(130℃),template-free hydrothermal route using low cost LiOH,Fe(NO3)3 and NH4H2PO4 as starting raw materials.These microspheres are composed of densely aggregated LiFePO4 nanoparticles and filled with interconnected mesochannels,which demonstrates not only a high tap density(≥1.4 g cm-3),a high capacity of 150 mAh g-1(~90% of its theoretical capacity) at 0.5 C rate,but also a ≥ 80% utilization of its theoretical capacity at a high rate of 1 C.In addition,the hydrothermal synthesis developed in this work is simple and cost-effective,it may provide a new route for production of the LiFePO4 material in battery applications. | ZHOU Min QIAN JiangFeng CAO YuLiang YANG HanXi | 2012 | Chinese Science Bulletin2012，57，32： | 2 |
| 6 | 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 |
| 7 | Improved Initial Charging Capacity of Na-poor Na0.44MnO2 via Chemical Presodiation Strategy for Low-cost Sodium-ion Batteries显示文摘Sodium-ion batteries(SIBs)are promising for grid-scale energy storage applications due to the natural abundance and low cost of sodium.Among various Na insertion cathode materials,Na0.44MnO2 has attracted the most attention because of its cost effectiveness and structural stability.However,the low initial charge capacity for Na-poor Na0.44MnO2 hinders its practical applications.Herein,we developed a facile chemical presodiated method using sodiated biphenly to transform Na-poor Na0.44MnO2 into Na-rich Na0.66MnO2.After presodiation,the initial charge capacity of Na0.44MnO2 is greatly enhanced from 56.5 mA·h/g to 115.7 mA·h/g at 0.1 C(1 C=121 mA/g)and the excellent cycling stability(the capacity retention of 94.1%over 200 cycles at 2 C)is achieved.This presodiation strategy would open a new avenue for promoting the practical applications of Na-poor cathode materials in sodium-ion batteries. | ZHOU Xi LAI Yangyang WU Xiangjiang CHEN Zhongxue ZHONG Faping Al Xinping YANG Hanxi CAO Yuliang | 2021 | Chemical Research in Chinese Universities2021，37，2： | 1 |

| 10 | Remodeling tumor immunosuppressive microenvironment via a novel bioactive nanovaccines potentiates the efficacy of cancer immunotherapy显示文摘The clinical outcomes of cancer nanovaccine have been largely impeded owing to the low antigen-specific T cell response rate and acquired resistance caused by the immunosuppressive tumor microenvironment(TME).Here,we reported a tumor acidity-responsive nanovaccine to remodel the immunosuppressive TME and expand the recruitment of tumor infiltrating lymphocytes(TILs)using hybrid micelles(HM),which encapsulated colony stimulating factor 1 receptor(CSF1-R)inhibitor BLZ-945 and indoleamine 2,3-dioxygenase(IDO)inhibitor NLG-919 in its core and displayed a model antigen ovalbumin(OVA)on its surface(denoted as BN@HM-OVA).The bioactive nanovaccine is coated with a polyethylene glycol(PEG)shell for extending nanoparticle circulation.The shell can be shed in response to the weakly acidic tumor microenvironment.The decrease in size and the increase in positive charge may cause the deep tumor penetration of drugs.We demonstrated that the bioactive nanovaccine dramatically enhance antigen presentation by dendritic cells(DCs)and drugs transportation into M1-like tumor-associated macrophages(TAMs)and tumor cells via size reduction and increasing positive charge caused by the weakly acidic TME.Such bioactive nanovaccine could remodel the immunosuppressive TME into an effector T cells favorable environment,leading to tumor growth inhibition in prophylactic and therapeutic E.G7-OVA tumor models.Furthermore,combining the bioactive nanovaccine with simultaneous anti-PD-1 antibody treatment leads to a long-term tumor inhibition,based on the optimal timing and sequence of PD-1 blockade against T cell receptor.This research provides a new strategy for the development of efficient cancer immunotherapy. | Xiaoxue Xie Yi Feng Hanxi Zhang Qingqing Su Ting Song Geng Yang Ningxi Li Xiaodan Wei Tingting Li Xiang Qin Shun Li Chunhui Wu Xiaojuan Zhang Guixue Wang Yiyao Liu Hong Yang | 2022 | Bioactive Materials2022，7，10： | 1 |
