Constructing a one-dimensional Cu-coordination polymer-based cathode material for Li-ion batteries
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.CCDC:2283641.
