Abstract Conductive pastes are widely used in lithium batteries and other fields, and the conductive pastes prepared from carbon nanotubes have attracted much attention because of their good thermal stability, electrical conductivity, and other advantages, but the carbon nanotubes are prone to agglomeration, which affects their performance. This study aims to solve this problem and tries to disperse carbon nanotubes with green tea mixed with polyvinylpyrrolidone (PVP) and applied to lithium-ion batteries. Carbon nanotube conductive pastes with different green tea concentrations were prepared and characterized by SEM, DLS, and Raman spectroscopy to test their electrochemical performance in lithium-ion batteries. The results show that when the green tea addition is 4 g, its mixing with PVP has the best dispersion effect on carbon nanotubes. At this time, the carbon nanotubes had the smallest average diameter of 203.68 nm, the highest I_G/I_D ratio in the Raman spectrum (0.973 6), good dispersion stability, and the lowest resistivity of the resulting electrode sheet (0.091 Ω·cm). After the paste was used in lithium-ion batteries, the battery charge transfer resistance and Warburg impedance were low, and the specific capacity of 0.1C discharge reached 130.2 mAh/g, which was higher than that of 127.1 mAh/g when PVP was dispersed alone, and the specific capacity was 129.8 mAh/g after 100 cycles, with a discharge capacity retention of 99.8%, which was excellent in multiplicity performance and cycling performance. This suggests that the mixed dispersion of green tea and PVP carbon nanotubes has potential application in the field of lithium-ion batteries.
