NOVELTY - Ternary lithium battery separator slurry, comprises 50-70 pts. wt. composite binder, 200-300 pts. wt. N-methylpyrrolidone, 0.4-0.6 pts. wt. modified graphene oxide, 60-65 pts. wt. aromatic additives, 2-5 pts. wt. ceramic powder, and 300-400 pts. wt. dimethylformamide; and the preparation of modified graphene oxide includes (A1) adding graphene oxide and (3-mercaptopropyl)trimethylsilane into tetrahydrofuran and reacting at 55-65℃ for 20-22hours to obtain a mixed solution A, (A2) cooling the mixed solution A to room temperature, filtering, soaking with 30-35% hydrogen peroxide solution for 20-22 hours to obtain the mixed solution B, (A3) filtering the mixed solution B, placing the obtained filter residue in 0.15-0.25 mol/l lithium hydroxide aqueous solution for 3-4 hours to obtain the mixed solution C, and (A4) filtering the mixed solution C, washing with water and methanol three times respectively, and vacuum drying to obtain modified graphene oxide. USE - The ternary lithium battery seperator slurry is useful in lithium field of the battery, where the battery is lithium ion battery. ADVANTAGE - The ternary lithium battery diaphragm slurry has high specific surface area, good electrochemical, mechanical and thermal stability energy, and high ion passing rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the ternary lithium battery seperator slurry.
