The Ni₃V₂O₈@PGCHC composite was then prepared by in situ growth of Ni₃V₂O₈ via a hydrothermal method. The enlarged specific surface area of the PGCHC material (1788.2 m² g^–1) with the activated porous structure (1.5 nm) provides multiple active sites for the material.

Moreover, the graphitic carbon structure greatly improves the electrical conductivity, resulting in excellent multiplicity and electrochemical properties. The specific capacitance of Ni₃V₂O₈@PGCHC exhibits 1179.1 F g^–1 when the current density is at 1 A g^–1. The ASC device prepared by combining a Ni₃V₂O₈@PGCHC positive electrode and PGCHC negative electrode can reach 73% capacity retention after 5,000 cycles, and the Coulombic efficiency is close to 100%. A high energy density of 57.3 Wh kg^–1 was demonstrated at a power density of 850 W kg^–1.

The first type of recycled graphite, prepurified carbon residue (PCR), was obtained through reductive acid leaching and thermomechanochemical processes with a carbon content of 97.6%. The second type, prepurified concentrate (PConcentrate), was produced via thermal-assisted flotation and thermomechanochemical processes, with a carbon content of 98.6%. Both types of recycled graphite, PCR and PConcentrate, underwent further purification using either an ultrahigh-temperature (UHT) approach or a thermochlorine treatment (TCT). These were followed by an amorphous carbon coating process to meet the graphite specifications for battery use. The structural analyses confirmed that both PCR and PConcentrate met the specifications for battery-grade graphite after purification and carbon coating. The electrochemical assessments showed that cells with recycled graphite, PConcentrate-TCT and PCR-TCT, exhibited specific capacities of 99 and 96 mAh/g, respectively, comparable to 99 mAh/g achieved by cells with commercial NG at a 2C rate.
