Supercapacitors have emerged as a popular area of research due to their exceptional attributes, including excellent cycling life, admirable power density, and rapid charge/discharge capabilities. However, the low energy density significantly restricts its range applicable scenarios. Herein, grafting copolymerization technique was employed incorporate transition metals (nickel, cobalt) into molecular chain lignin, lignin-based pseudocapacitor material (Ni/Co@LC) is obtained after thermal treatment. XRD, X-ray photoelectron spectroscopy, scanning electron microscopy, dispersive spectrometry results demonstrate strong interaction between Ni/Co carbon, with encapsulated within carbon shell. Hence, Ni/Co@LC exhibits an approximately 69% increase in specific capacitance compared those conventional materials which coated on surface materials, equivalent series resistance reduced by about 50%. Moreover, assembled asymmetric supercapacitors Ni/Co@LC//LC achieve 52.89 W h kg-1 at 640 maintain retention rate 99.28% undergoing 10,000 charge-discharge cycles. This work presents novel approach for designing electrode impedance high performance.
