The invention discloses a nickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material for a lithium battery. The nickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material for the lithium battery is characterized in that bio-based nitrogen-doped porous carbon is one or two of bamboo carbon and bamboo shoot carbon, the specific surface area ofthe carbon material is 100-3,000m<2>/g and the content of a nitrogen element is 0.1-10.0wt.%. The particle sizes of nickel oxide-loaded nanoparticles are 5-500nm. The nickel oxide nanoparticles are dispersed into a tetrahydrofuran solvent for ultrasonic treatment for 30min and dispersed evenly; porous carbon is added for further ultrasonic treatment for 20min; the mixed solution is centrifuged ata high speed, washed by using deionized water and dried through an oven to obtain nickel oxide-loaded bio-based nitrogen-doped porous carbon as a negative electrode material for the lithium-ion battery; a CR2025 button half-battery is assembled and the electrochemical properties of the nickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material are tested. According to the nickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material, the first charge-discharge cyclic specific capacity can reach 1084mAhg<-1> under the current density of 100mAg<-1> and is much higher than 370mAhg<-1> of a commercial carbon negative electrode material, the nickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material still has a specific capacity value of 510mAhg<-1> after 50 charge-discharge cycles and the specific capacity value is also much higher than that of the commercial carbon negative electrode material. Therefore, thenickel oxide-loaded bio-based nitrogen-doped porous carbon negative electrode material can be used as a substitute material of a traditional commercial carbon negative electrode material for the lithium-ion battery.
