NOVELTY - Molybdenum disulfide nanosheet/nanocellulose/carbon nanotube/graphene composite flexible lithium battery film anode material, is claimed. The anode material is obtained by taking nanocellulose as a flexible substrate, nanosheet molybdenum disulfide, carbon nanotube and graphene, mixing, burying in the nano-cellulose network and forming a dense network structure of flexible self-supporting thin film electrode material. The thin film electrode material composition as follows: 60-80 wt.% molybdenum disulfide nanosheet, 10-30 wt.% nano-cellulose, 5-20 wt.% carbon nanotube and 5-20 wt.% graphene. USE - Used as molybdenum disulfide nanosheet/nanocellulose/carbon nanotube/graphene composite flexible lithium battery film anode material. ADVANTAGE - The method does not utilize metal foil and copper foil, greatly avoids ecological hazards and environmental impact. The anode material has good mechanical flexibility and continuous bending stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the molybdenum disulfide nanosheet/nanocellulose/carbon nanotube/graphene composite flexible lithium battery film anode material, comprising (i) ball milling molybdenum disulfide powder for 20-30 minutes, adding mass percentage concentration of 40-50 wt.% ethyl alcohol and water mixed solvent, uniformly dispersing, adding percentage concentration of 1-3 wt.% nano cellulose aqueous dispersion liquid, mixing uniformly, and primary ultrasonic processing under power of 600-900W and amplitude transformer diameter of 0.6 mm at 10-20 degrees C for 8-20 hours to obtain small layer molybdenum disulfide nanosheet/nano-cellulose mixed dispersion; (ii) adding graphene into the dispersion, ultrasonic peeling for 2-3 hours, adding carbon nanotube, continuing ultrasonic peeling for 0.5-1 hour, dispersing uniformly to form molybdenum disulfide nanosheet/nano cellulose/graphene/carbon nanotube mixed dispersion; (iii) diluting the mixed dispersion with deionized water to obtain 20-30% mass concentration molybdenum disulfide nanosheet/nano cellulose/graphene/aqueous carbon nanotube dispersion liquid, filter pressing, extruding sion, and burying molybdenum disulfide nanosheet/graphene nanosheet/carbon nanotube in the nanocellulose network to form a wet film dense network structure; and (iv) drying the wet film.
