A one-step hydrothermal method was employed, using urea (H2NCONH2) as an interlayer modulation agent, to realize the in situ growth of molybdenum disulfide (MoS2) within a three-dimensional conductive network constructed by carbon nanotubes (CNTs). MoS2@CNT composite was prpared and used as anode materials for sodium ion batteries, and theri electrochemical properties investigated. The results indicate that the MoS2@CNT composite materials can effectively alleviate volume expansion during sodium-ion insertion and extraction, thereby improving the sodium storage reaction kinetics and structural stability. Structural characterization results reveal that the incorporation of H2NCONH2 increases the interlayer spacing of MoS2 from 0.62 nm to 0.71 nm, thereby providing additional active sites and shortening ion diffusion pathways. Electrochemical properties test results demonstrate that, after 100 cycles at a current density of 0.1 A/g, the composite maintains a reversible capacity of 387.2 mAh/g, corresponding to a capacity retention rate of 97.5%. Furthermore, after cycling at various current densities, the specific capacity recovers to 402.3 mAh/g, indicating excellent rate capability and superior cycling stability.

研究了采用一步水热法,以尿素(H2NCONH2)为扩层调控剂,促使二硫化钼(MoS2)在碳纳米管(CNT)构建的三维导电网络中的原位生长,制备了MoS2@CNT复合材料并用作钠离子电池的负极材料,同时考察了其电化学性能。研究结果表明,MoS2@CNT复合材料在钠离子嵌入与脱出过程中起到缓解体积膨胀的作用,改善了其储钠反应动力学及结构稳定性。结构分析结果表明,加入H2NCONH2后,MoS2的层间距由0.62 nm扩展至0.71 nm,能提供更多反应活性位点,并有效缩短离子迁移路径。电化学性能测试结果表明,该材料在0.1 A/g电流密度条件下循环100次后,可逆容量仍可保持在387.2 mAh/g,保持率达97.5%;经过不同电流密度测试后,其比容量还能恢复至402.3 mAh/g,倍率性能良好,具有优异的循环稳定性。

研究了采用一步水热法,以尿素(H2NCONH2)为扩层调控剂,促使二硫化钼(MoS2)在碳纳米管(CNT)构建的三维导电网络中的原位生长,制备了MoS2@CNT复合材料并用作钠离子电池的负极材料,同时考察了其电化学性能。研究结果表明,MoS2@CNT复合材料在钠离子嵌入与脱出过程中起到缓解体积膨胀的作用,改善了其储钠反应动力学及结构稳定性。结构分析结果表明,加入H2NCONH2后,MoS2的层间距由0.62 nm扩展至0.71 nm,能提供更多反应活性位点,并有效缩短离子迁移路径。电化学性能测试结果表明,该材料在0.1 A/g电流密度条件下循环100次后,可逆容量仍可保持在387.2 mAh/g,保持率达97.5%;经过不同电流密度测试后,其比容量还能恢复至402.3 mAh/g,倍率性能良好,具有优异的循环稳定性。

A one-step hydrothermal method was employed, using urea (H2NCONH2) as an interlayer modulation agent, to realize the in situ growth of molybdenum disulfide (MoS2) within a three-dimensional conductive network constructed by carbon nanotubes (CNTs). MoS2@CNT composite was prpared and used as anode materials for sodium ion batteries, and theri electrochemical properties investigated. The results indicate that the MoS2@CNT composite materials can effectively alleviate volume expansion during sodium-ion insertion and extraction, thereby improving the sodium storage reaction kinetics and structural stability. Structural characterization results reveal that the incorporation of H2NCONH2 increases the interlayer spacing of MoS2 from 0.62 nm to 0.71 nm, thereby providing additional active sites and shortening ion diffusion pathways. Electrochemical properties test results demonstrate that, after 100 cycles at a current density of 0.1 A/g, the composite maintains a reversible capacity of 387.2 mAh/g, corresponding to a capacity retention rate of 97.5%. Furthermore, after cycling at various current densities, the specific capacity recovers to 402.3 mAh/g, indicating excellent rate capability and superior cycling stability.
