LITHIUM TITANATE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR, NEGATIVE ELECTRODE PLATE, AND LITHIUM ION BATTERY

摘要

A lithium titanate composite material and a preparation method therefor, a negative electrode plate, and a lithium ion battery, relating to the technical field of batteries, the preparation method for the lithium titanate composite material comprising the following steps: 1) preparing a ruthenium dioxide/titanium dioxide composite; 2) using the ruthenium dioxide/titanium dioxide composite and a lithium source as raw materials, preparing a lithium titanate composite material. A lithium titanate composite material prepared using said method. A negative electrode plate comprising said lithium titanate composite material. A lithium ion battery comprising said negative electrode plate. Thus, a lithium titanate composite material having good electrical conductivity is provided; when used as the active material of a negative electrode plate of a lithium ion battery, the lithium titanate composite material can improve the rate capability of the battery.
