[Display omitted] •The taxifolin oxidation at Ni-MOF/CNTs is an adsorption-diffusion process.•Ni-MOF/CNTs sensor displays wide linear range and low detection limit.•Ni-MOF/CNTs exhibits superior cycling stability and rate capability in LIB. Nickel-based metal organic framework (Ni-MOF) and carbon nanotubes composite (Ni-MOF/CNTs) is constructed via in situ self-assembly of Ni-MOF in the presence of CNTs solution. The obtained electrode (Ni-MOF/CNTs) exhibits sensitive response toward the detection of taxifolin by significantly enhancing the redox peak currents and decreasing the peak-to-peak separation. Under the selected conditions, the peak current linearly relates with taxifolin concentration in the range of 4.0 × 10−8 ~ 1.0 × 10−5 mol L−1 with the detection limit of 1.33 × 10−8 mol L−1 (S/N = 3). Otherwise, the lithium storage results reveal that Ni-MOF/CNTs with enhanced conductivity exhibits benign cycling stability and rate capability, with coulomb efficiency around 100%. This Ni-MOF/CNTs electrode may lay the foundation for the Ni-MOF based materials in electrochemical application.
