The invention provides a lithium titanate composite material and a preparation method thereof and a lithium ion battery negative electrode material and a lithium ion battery, and relates to the fieldof batteries. The lithium titanate composite material comprises cobalt acid zinc and lithium titanate, wherein a weight ratio of the cobalt acid zinc and the lithium titanate is (1-8):100. The lithiumtitanate composite material is a block structure formed by stacking sheet layers. The lithium titanate composite material can be used for relieving a technical problem that a specific capacity of thelithium ion battery negative electrode material is low and the cycling performance is bad, and achieving the technical effect of improving the specific capacity and the cycling performance thereof.
