The cathode materials of the aqueous zinc ion battery (ARZIBs) have been continuously developing, MoS2 has been enhanced to address issues such as poor conductivity, high internal resistance, and slow ion transmission. Here, a heterogeneous composite structure of MoS2 nanosheets is grown on the surface of hard carbon spheres provided by glucose as a precursor (MoS2 @CNPs). The lattice spacing increased from 0.62 nm to 0.97 nm due to the heterogeneous structure of MoS2 @CNPs. The results reveal that the compound MoS2 with carbon nanomaterials heterogeneous structure can enlarge lattice the spacing of MoS2 , decrease the energy barrier for zinc ion insertion, and improve the charge transfer capability. Therefore, a heterogeneous MoS2 @CNPs hybrid delivers better cycling stability and performance ratio.

异质MoS2@CNPs混合,具有更大的层间距,适用于水性可充电锌离子电池
水性锌离子电池 (ARZIBs) 的正极材料不断发展,MoS2 得到了增强,以解决导电性差、内阻高和离子传输缓慢等问题。在这里,MoS2 纳米片的异质复合结构生长在葡萄糖作为前驱体 (MoS2@CNPs) 提供的硬碳球表面。由于 MoS2@CNPs 的异质结构,晶格间距从 0.62 nm 增加到 0.97 nm。结果表明,具有碳纳米材料异质结构的化合物 MoS2 可以扩大 MoS2 的晶格间距,降低锌离子插入的能垒,并提高电荷转移能力。因此,异质 MoS2@CNPs 混合动力车提供更好的循环稳定性和性能比。
