Nanostructure-based anode material for lithium ion batteries and method of making the same

Abstract

The application belongs to the technical field of batteries, and particularly relates to a lithium ion battery negative electrode material based on nanostructures and a preparation method thereof. The preparation method comprises the following steps: S1, mixing iron salt, cobalt salt, lanthanum salt, a first carbon source and water, and then performing freeze drying to obtain a precursor; S2, performing joule heat shock on the precursor to obtain an intermediate A; S3, performing ball milling on the intermediate A and a second carbon source to obtain an intermediate B; and S4, performing sintering on the intermediate B to obtain the lithium ion battery negative electrode material. The lithium ion battery negative electrode material based on nanostructures prepared in the application can simultaneously achieve the effects of high capacity, high initial efficiency and long cycle life.
