A preparation method for a modified lithium titanate negative electrode material: a cladding material precursor undergoes a composite treatment, is then added with a certain amount of a resin curing agent, and then undergoes atomization, thus dispersing a cladding material into superfine droplets, enhancing the fluidity and dispersibility of the composite cladding material, and then fully cladding lithium titanate; also, when cured, a resin provides a frame supporting effect and prevents the phenomenon of a damaged cladding layer due to asphalt melting in the carbonization process and causing agglomeration when the material is carbonized and thus requiring same to undergo a crushing treatment. Employment of the method of the present invention ensures the evenness in mixing various cladding material precursors, obviates the need for any solvent, and is environmentally friendly; in addition, process is simple, inexpensive, and easy for industrialized production. |
