摘要:
以3-氨基-1, 2, 4-三唑和硼酸为原料，通过蒸发溶剂-原位热聚合法制备了硼改性富氮氮化碳(B/C3N5)，通过一系列表征技术对材料的物相晶型、化学基团、微观形貌和化学组成等进行了分析，作为载体材料负载单质硫应用于锂硫纽扣电池正极材料。结果表明：B/C3N5-20作为载体材料负载单质硫构成的正极材料组装锂硫纽扣电池，表现出优异的电化学性能。放电倍率为0.1C时，放电的比容量最高达到了1 002.15mAh/g，库伦效率达到了99.78%，循环300次后放电的比容量为518.03mAh/g，表现出良好的循环稳定性。放电倍率为4.0C时，放电比容量仍达到了555.82mAh/g，表现出良好的倍率性能。锂硫纽扣电池良好的电化学性能得益于非金属B掺杂后取代C3N5结构中的C原子形成B?N化学键，提高了极性位点的数量，有效抑制了多硫化锂的穿梭效应，提高了导电性。
Abstract:
Boron-modified nitrogen-rich carbon nitride (B/C3N5) was prepared by evaporation solvent-in-situ thermal polymerization using 3-amino-1,2,4-triazole and boric acid as raw materials. The crystal phase, chemical group, microstructure and chemical composition of the material were analyzed by a series of characterization techniques. It was used as a carrier material to load elemental sulfur and applied to the cathode material of lithium-sulfur button batteries. The results show that the lithium-sulfur button battery assembled with B/C3N5-20 as the carrier material loaded with elemental sulfur exhibits excellent electrochemical performance. When the discharge rate is 0.1C, the specific capacity of the discharge reaches 1 002.15mAh/g, and the coulombic efficiency reaches 99.78%. After 300 cycles, the specific capacity of the discharge is 518.0 3mAh/g, showing better cycle stability. At a discharge rate of 4.0C, the discharge specific capacity still reaches 555.82mAh/g, showing better rate performance. The good electrochemical performance of lithium-sulfur button batteries is due to the formation of B?N chemical bonds by replacing the C atoms in the C3N5structure with non-metallic B doping, which increases the number of polar sites, effectively inhibits the shuttle effect of lithium polysulfide, and improves the conductivity
