| 摘要: 合成了一种新型的一维(1D)羰基配位聚合物[Cu (BGPD)(DMA)(H2O)]·DMA (记为Cu-BD，H2BGPD=N，N′-双(甘氨酰)均苯四甲酸二酰亚胺，DMA=二甲基乙酰胺)，并考察了其用作锂离子电池正极材料的电化学性能。电化学测试结果表明，Cu-BD正极在50 mA·g-1的电流密度下循环100圈后仍然保留50 mAh·g-1的比容量，具有较好的循环稳定性。Cu-BD电极反应机理研究表明，BGPD2-配体和Cu (Ⅱ)离子在充放电过程中都可能参与了电子转移过程。 | |

| Abstract: A novel one-dimensional (1D) polycarbonyl coordination polymer [Cu(BGPD)(DMA)(H2O)]·DMA (named Cu-BD, H2BGPD=N,N′-bis(glycinyl)pyromellitic diimide; DMA=dimethylacetamide) was synthesized, and evaluated as a cathode material for lithium - ion batteries (LIBs) for the first time. The electrochemical performance study revealed that the Cu-BD cathode exhibited better cycling stability and a specific capacity of 50 mAh·g-1 after 100 cycles at a current density of 50 mA·g-1. The study of the reaction mechanism for the Cu-BD electrode discloses that both BGPD2- ligands and Cu(Ⅱ) ions may take part in the electron-transfer process during charging and discharging. | |
