Abstract ：
Micron-sized Si-based materials have attracted extensive attention for lithium-ion batteries due to their high theoretical capacity and low cost. However, its large volume expansion and low conductivity limit its further development. Here, a Si/ZnS anode material is prepared, in which ZnS nanoparticles are uniformly attached to the surface of micro-Si particles. The conversion reaction of ZnS generates metal Zn and Li2S, and the alloying reaction of Zn generates LixZn, the metal Zn and LixZn are used as conductive additives to improve the conductivity of the composites, while Li2S is used as an artificial solid electrolyte interfacial phase to promote the stability of the solid electrolyte interface of the composites, so that the prepared micron-sized Si-based anode exhibits excellent cycling stability. At a current density of 0.5 A g-1, the initial coulombic efficiency reaches 78.67 % and the discharge specific capacity is 1540.2 mAh g-1 after 200 cycles.

Abstract ：
In the field of lithium battery research, silicon has received extensive attention due to its high specific capacity and abundant reserves, but the factors such as large volume expansion and low electrical conductivity limit its further development. In this work, Si/Bi2S3 composites with a heterogeneous structure is obtained by using a hydrothermal reaction. The heterogeneous structure can promote the rapid transfer of charge, and the interfacial coupling effect of the heterogeneous structure has an adsorption effect on Li2S generated by the conversion reaction of Bi2S3, and Li2S is distributed on the surface of the Si/Bi2S3 composite to become an effective component of solid electrolyte interface (SEI), promoting the stability of the SEI film. The Bi and LixBi (x = 1, 3) produced during the conversion and alloying reactions of Bi2S3 can reduce the internal resistance of the Si/Bi2S3 composite. Thus, at a current density of 500 mA g-1, the initial charge -discharge specific capacity of Si/Bi2S3 is 2240.5/2767.8 mAh g-1. After 200 cycles, the discharge specific capacity can achieve 1443.3 mAh g-1, with a capacity retention of 52.1 %.

Abstract ：
We introduced a Si/SnS2 anode material with a high energy density and excellent cycle stability. The structure of this Si/SnS2 composite material is nanosized SnS2 coated on the surface of nanosilicon. Using the structural advantages of the coating structure, combined with the lithium storage mechanism of tin disulfide, the performance of silicon materials has been improved from three aspects: alleviating the volume expansion effect, improving the stability of the solid electrolyte interface (SEI), and enhancing the electrical conductivity. The material exhibits very excellent performance when applied to lithium-ion battery anodes. At the current density of 0.5 Ag(-1), the specific discharge capacity of the electrode material is maintained at 2217 mAhg(-1) after 100 cycles, and the capacity retention rate reached 65.3%. It also has high Coulombic efficiency of 86.1% for the first cycle and 96-99.9% for the following cycles.

Abstract ：
The Si material of the highest theoretical capacity (4200 mAh.g(-1)) cannot be commercially applied in real life owing to its vast volume expansion during the charge-discharge process and low electrical conductivity. Here, we introduce a Si@SnO2 material with a coating structure, in which SnO2 is coated on the surface of the silicon material. The coating structure can effectively alleviate the volume expansion stress of the silicon material. The Sn produced by the reaction of SnO2 with Li during the first cycle has good conductivity, thereby improving the electrochemical performance of the silicon material. The electrochemical performance of the material is excel-lent. At the current density of 0.2A.g(-1), the first coulombic efficiency of the battery reaches 84.1%, and the specific discharge capacity of the battery can be reached at 1926mAh.g(-1) after 200 cycles.

Abstract ：
Using a simple hydrothermal method, we developed a Si@SnS anode material with SnS nanoparticles uni-formly attached to the surface of silicon nanoparticles. Utilizing the first charge-discharge reaction mech-anism of SnS, combined with the artificial solid electrolyte interphase to improve the solid electrolyte interphase stability of silicon-based materials and the introduction of conductive additives to improve the conductive properties of silicon-based materials, the Si@SnS material exhibits very excellent perfor-mance when applied to lithium-ion battery anodes. At a current density of 0.5A.g-1,after two cycles, the overall resistance of the Si@SnS material battery is reduced by nearly 55% relative to the resistance of the pure silicon battery. As a half-cell anode material, the first coulombic efficiency of Si@SnS at a current density of 1A.g -1 reached 85%, and after 200 cycles, it provided a reversible capacity of 1790 mAh.g -1 and a capacity retention rate of 74.6%.

Abstract ：
The amorphous carbon was coated on the surface of the nano-silicon with citric acid by a simple mechanical stirring in water bath method and high temperature pyrolysis method, and then the carbon-coated silicon composite material(Si@C) was coated with polyvinyl alcohol by the secondary mechanical stirring and high temperature pyrolysis to obtain double carbon layer-coated silicon composite material (Si@C@C). The microstructure and surface morphology of Si@C@C were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrochemical properties of Si@C@C were investigated by constant current charge-discharge, cyclic voltammetry, and electrochemical impedance spectra techniques. The study found that the first reversible specific capacity of Si@C@C was 1669 mAh/g at the current density of 0.1 C. The specific capacity remained at 1300 mAh/g, while the capacity retention rate was 77.9% after 200 cycles. The cyclic stability of Si@C@C was higher than that of Si@C, which greatly improved the electrochemical performance of silicon-based materials as anode materials for lithium ion batteries.

Abstract ：
选取龙岩(LY)和上京(SJ)两种福建低灰熔点煤,利用灰熔点测定仪研究氧化铝、氧化钙及铝钙复合物对两种煤灰熔融温度的影响规律.研究结果表明:加入Al2O3(4％～18％,质量分数,下同)可以一直提高灰熔点,加入CaO(2％～8％)使灰熔点降低.但LY灰、SJ灰中添加较多Al2O3后再加少量CaO可使灰熔点比对应只加Al2 O3的高,表现出铝钙协同作用.通过XRD和SEM-EDX分析煤灰在高温下的矿物转化行为、表面微观形貌及化学组成,研究铝钙协同作用对低灰熔点煤的影响规律及其机理.结果发现:加入氧化铝后,煤灰在高温下生成的耐熔矿物莫来石是提高灰熔点的主要因素;加入较高含量的氧化铝和少量的氧化钙后,灰中先生成莫来石矿物,其中的氧化钙则会生成钙长石;在有莫来石存在时,钙长石与莫来石一起导致其熔融温度升高,从而提高灰熔点.
