Abstract

With the development of new energy technologies, the negative electrode materials of lithium-ion batteries cannot meet the demand for higher energy storage because of the low specific capacity and poor rate characteristics. Metal-Organic Frameworks (MOFs), a new type of functional material, have broad application potential in energy storage field due to the adjustable pore structure and abundant active sites. However, poor conductivity and weak stability are its fatal defects. Therefore, NiCo-BDC/Multi-Wall Carbon Nanotubes (MWCNT) composites have been synthesized through hydrothermal method to address these issues. The adding of MWCNT can significantly improve the conductivity and stability of the composites. As a result, the rate performance and cycle life of the composites have been enhanced evidently. NiCo-BDC/MWCNT has a specific capacity of 659 mAh g^-1 at 0.1 A g^-1, and no significant decrease in capacity can be observed after 50 cycles at 0.2 A g^-1, which indicates the great application prospects of NiCo-BDC/MWCNT composites in lithium-ion batteries.
