Abstract：In order to solve environmental requirements such as energy shortage, supercapacitors have gradually emerged in people's vision due to their advantages of fast charging and discharging and excellent energy storage performance. Among them, electrode material is a key factor affecting the performance and cost of supercapacitors. Due to its unique performance, carbon materials were the first batch of materials used in supercapacitors. Therefore, on the basis of functionalization of carbon nanotubes, this work studied the addition of carbon quantum dots and functionalized carbon nanotubes to cobalt aluminum bimetallic hydroxides, and the synthesis of CQDs/CoAl LDH and FMWCNTs/CoAl LDH binary composites increased the specific surface area of bimetallic hydroxides, made the structure more stable, and improved the conductivity, specific capacitance, and electrochemical cycle stability.
