| 1 | Advanced chemical strategies for lithium-sulfur batteries: A review显示文摘Lithium-sulfur(Li-S) battery has been considered as one of the most promising rechargeable batteries among various energy storage devices owing to the attractive ultrahigh theoretical capacity and low cost. However, the performance of Li-S batteries is still far from theoretical prediction because of the inherent insulation of sulfur, shuttling of soluble polysulfides, swelling of cathode volume and the formation of lithium dendrites. Significant efforts have been made to trap polysulfides via physical strategies using carbon based materials, but the interactions between polysulfides and carbon are so weak that the device performance is limited. Chemical strategies provide the relatively complemented routes for improving the batteries' electrochemical properties by introducing strong interactions between functional groups and lithium polysulfides. Therefore, this review mainly discusses the recent advances in chemical absorption for improving the performance of Li-S batteries by introducing functional groups(oxygen, nitrogen, and boron, etc.) and chemical additives(metal, polymers, etc.) to the carbon structures, and how these foreign guests immobilize the dissolved polysulfides. | Xiaojing Fan Wenwei Sun Fancheng Meng Aiming Xing Jiehua Liu | 2018 | Green Energy & Environment2018，3，1： | 7 |
| 2 | Superhydrophobic fluoride conversion coating on bioresorbable magnesium alloy——fabrication,characterization,degradation and cytocompatibility with BMSCs显示文摘A micro-nano structure CaF_(2)chemical conversion layer was prepared on fluoride-treated AZ31 alloy,then the composite fluoride conversion film(CaF_(2)/MgF_(2))was modified by stearic acid(SA)and fabricated a superhydrophobic surface.The fluoride-treated magnesium,fluoride conversion film and superhydrophobic coating were characterized by SEM,EDS,XRD and FTIR.The properties of coatings1 adhesion and corrosion resistance were evaluated via tape test and electrochemical measurement.The cytocompatibility of the MgF_(2),CaF_(2)and superhydrophobic CaF_(2)/SA surface was investigated with bone marrow-derived mesenchymal stem cells(BMSCs)by direct culture for 24 h.The results showed that the superhydrophobic fluoride conversion coating composed of inner MgF_(2)layer and the outer CaF_(2)/SA composite layer had an average water contact angle of 152°.SA infiltrated into the micro-nano structure CaF_(2)layer and formed a strong adhesion with CaF_(2)layer.Furthermore,the super-hydrophobic coating showed higher barrier properties and corrosion resistance compared with the fluoride conversion film and fluoride-treated AZ31 alloy.The BMSC adhesion test results demonstrated MgF_(2)CaF_(2)and CaF_(2)/SA coatings were all nontoxic to BMSC.At the condition of in direct contact with cells,MgF_(2)showed higher cell density and enhanced the BMSCs proliferation,while CaF_(2)and CaF_(2)/SA coating showed no statistically difference in cell density compared with glass reference but the CaF_(2)and CaF_(2)/SA coating were not conducive to BMSCs adhesion. | Chunyan Zhanga Shiyu Zhang Dongwei Sun Jiajia Lin Fancheng Meng Huinan Liu | 2021 | Journal of Magnesium and Alloys2021，9，4： | 3 |
| 3 | Applications of Transition Metal(Fe,Co,Ni)-Based Metal–Organic Frameworks and their Derivatives in Batteries and Supercapacitors显示文摘Metal–organic frameworks(MOFs),which are generally considered to be crystalline materials comprising metal centers and organic ligands,have attracted growing attention because of their controllable structures and high porosity.MOFs based on transition metals(Fe,Co,Ni)are highly effi cient electrode materials for electrochemical energy storage.In this review,the characteristics of Fe-MOFs,Co-MOFs,Ni-MOFs,and their derivatives are summarized,and the relationships between the structures and performance are unveiled in depth.Additionally,their applications in lithium–ion batteries,lithium–sulfur batteries,and supercapacitors are discussed.This review sheds light on the development of MOFs and their derivatives to realize excellent electrochemical performance. | Xinguo Jin Yuying Shan Fancheng Sun Huan Pang | 2022 | Transactions of Tianjin University2022，28，6： | 0 |
| 4 | A controllable preparation of two-dimensional cobalt oxalate-based nanostructured sheets for electrochemical energy storage显示文摘Well-defined two-dimensional(2D)cobalt oxalate(CoC_(2)O_(4)·2H_(2)O)nanosheets exhibit more excellent property than common bulk cobalt oxalate due to high specific surface areas and high-efficient transport of ion and electron.However,the delicate control of the 2D morphology of CoC_(2)O_(4)·2H_(2)O during their synthesis remains challenging.Herein,2D CoC_(2)O_(4)·2H_(2)O nanosheets(M1),grown by straightforward chemical precipitation,can be tuned from three-dimensional(3D)structure during their synthesis with no templates or capping agents.This control is obtained by rationally changing the ratio of reactants with ethylene glycol as solvent.Moreover,Co_(3)O_(4)/CoC_(2)O_(4)composites(M1-250)have been fabricated through low-temperature thermal treatment of the M1 precursor in air,which possess porous surfaces with the 2D morphology maintained.Benefiting from the porous surfaces,more redox-active sites and better electrical conductivity of Co_(3)O_(4),the constructed M1-250//AC aqueous device manifest improved kinetics of the electrochemistry process with energy density of 27.9 Wh/kg at 550.7 W/kg and good cycling stability with sustaining 73.0 m Ah/g after 5000 cycles. | Fancheng Sun Qing Li Yang Bai Guangxun Zhang Shasha Zheng Maoying Peng Xudong Chen Nuo Lin Huan Pang | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
