PREPARATION METHOD FOR MODIFIED LITHIUM TITANATE NEGATIVE ELECTRODE MATERIAL

WIPO Patent Application WO/2016/165390

A1

Disclosed is a preparation method for a modified lithium titanate negative electrode material. The preparation method for the modified lithium titanate negative electrode material, in which raw materials are proportioned according to parts by weight, comprises the following process steps: (1) preparation of lithium titanate; (2) the lithium titanate, an epoxy resin, and nano-silica are mixed into a uniform slurry; (3) lithium titanate powder is produced by spray drying; and, (4) under the protection of a noble gas, the powered produced in step (3) undergoes a high temperature treatment to produce the modified lithium titanate negative electrode material. The present invention allows preparation of lithium titanate via a solid phase method and has the advantages of a simple process, inexpensive manufacturing costs, and a short production cycle.
