▎ 摘  要

NOVELTY - Lithium battery anode material comprises 30-45 pts. wt. carbon fluoride, 100-120 pts. wt. anode base material, 10-25 pts. wt. nanodiamondene, 10-15 pts. wt. silicon dioxide, 12-22 pts. wt. iron oxide, 20-30 pts. wt. ethylene glycol, 10-18 pts. wt. solid paraffin, 22-35 pts. wt. manganese source, 25-45 pts. wt. barium hydroxide and 15-25 pts. wt. nickel alloy powder. The anode substrate is set as ternary anode material is LiaNixCoyMnzO2, where a = 0.9-1.2, x+y+z=1, x = 0.5-1, y = 0-0.25 and z = 0-0.25. The manganese source comprises at least one of manganese monoxide, manganese dioxide, manganese trioxide, manganese tetroxide, manganese carbonate, basic manganese carbonate, manganese oxyhydroxide and/or manganese oxalate. The fluorinated carbon is mixture of at least one of fluorinated carbon black, fluorinated flake graphite, fluorinated petroleum coke, fluorinated carbon fiber, fluorinated mesocarbon microspheres, and/or fluorinated graphene. USE - The lithium battery anode material is useful for mobile electronic device, mobile phone, portable computer and other power supply and in lead-acid battery nickel-cadmium battery. ADVANTAGE - The lithium battery anode material: has improved processing performance in the battery preparation process; simplifies the preparation process thus saves the production cost; prolongs the cycle service life of the battery; and provides improved cycle performance, thermal stability, electrochemical performance and performance safety. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing lithium battery anode material.
