| 1 | Sulfur-encapsulated in heteroatom-doped hierarchical porous carbon derived from goat hair for high performance lithium–sulfur batteries显示文摘Biomass-derived carbon materials have aroused widespread concern as host material of sulfur to enhance electrochemical performances for lithium–sulfur batteries. Herein, goat hair, as a low-cost and eco-friendly precursor, is employed to fabricate cauliflower-like in-situ nitrogen, oxygen and phosphorus tri-doped porous biomass carbon(NOPC) by a facile activation with H_3PO_4 and carbonization process.The morphology and microstructure of NOPC can be readily tuned by altering pyrolysis temperature. The as-prepared NOPC matrix material carbonized at 600 °C possesses 3D hierarchical porous structure, high specific surface area(535.352 m^2 g^(-1)), and appropriate pore size and pore size distribution. Encapsulating sulfur into the NOPC depends on a stem-melting technology as cathode materials of Li–S batteries. Due to the synergistic effect of special physical structure and inherent tri-doping of N, O and P, electrons and ions transfer and utilization of active sulfur in the materials are improved, and the shuttle behaviors of soluble lithium polysulfides are also mitigated. Consequently, the S/NOPC-600 composite exhibits excellent electrochemical performance, giving a high initial discharge capacity of 1185 mA h g^(-1) at 0.05 C and maintaining a relatively considerable capacity of 489 m A h g^(-1) at 0.2 C after 300 cycles. Our work shows that a promising candidate for cathode material of Li–S batteries can be synthesized using low-cost and renewable biomass materials by a facile process. | Juan Ren Yibei Zhou Huali Wu Fengyu Xie Chenggang Xu Dunmin Lin | 2019 | Journal of Energy Chemistry2019，28，3： | 9 |

| 14 | Metal-organic frameworks derived carbon-coated ZnSe/Co_(0.85)Se@N-doped carbon microcuboid as an advanced anode material for sodium-ion batteries显示文摘Transition metal selenides attract significant attention as advanced anode materials for sodium-ion batteries(SIBs)in recent years due to their appropriate working potential and high theoretic capacity.However,the poor structural stability and rate capability limit their further practical applications.Herein,zeolite imidazole framework-8/zeolite imidazole framework-67 is used as a template to prepare Co_(0.85)Se and Zn Se nanoparticles embed in N-doped carbon matrix successfully,and then coated a carbon layer(ZCS@NC@C)by in-situ polymerization.One side,the N-doped carbon matrix with rich pore structure not only shorten the diffusion path of Na^(+) and improve the conductivity of the electrode,but also prevent structural collapse and agglomeration of active particles during the sodium insertion/extraction process.On the other side,the carbon shell preparation by coating can form a protective layer to buffer the volumetric stress generated in the electrochemical process and further improve the electrical conductivity.As a result,the as-prepared ZCS@NC@C anode material exhibits an excellent electrochemical performance for SIBs.This investigation provides a promising approach to optimize the electrochemical performance of SIBs by incorporating active metal compounds into conductive carbons to form multidimensional structure. | Xiaoyan Li Xiaoqin Liu Yu Xiang Qiaoji Zheng Xijun Wei Dunmin Lin | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
