Abstract

The invention belongs to the preparation field of the anode material of a lithium ion battery, and in particular relates to a method for preparing metal oxide electrode material with a nanometer structure by utilizing the in-situ synthesis method. The internal structure and the dimension of a hollow micro-sphere obtained are controlled through adjusting the pH value of a system by utilizing hydrochloric acid. Raw materials in the invention are common and are easy to obtain; an organic solvent is not required during the preparation process; the preparation process is simple; the synthesis of template materials and the participation of a surface active agent are not required during the synthetic process; the requirements to the device are low, the time consumption is less and the preparation process is simple; and a main by-product during the preparation process is water and carbon dioxide and is environment-friendly. The raw materials used in the invention are common; and the preparation conditions are not restricted by areas. The hollow tin dioxide micro-spheres have higher application prospect in the filed of electrode material, catalyst carriers and the like. The method has the advantages of cheap and easily obtained raw materials, simple preparation process, and unrestricted preparation conditions by areas, and is suitable for massive industrial production.

Description

technical field

[0001] The invention belongs to the field of lithium ion battery negative electrode material preparation, and in particular relates to a method for preparing a metal oxide battery negative electrode material with a nanometer structure by using an in-situ synthesis method. Background technique

[0002] Due to the limited reserves of fossil energy in the world and the increasingly serious environmental pollution problems, people gradually began to develop and utilize new, abundant and cheap energy sources. Due to its high output voltage, large battery capacity, long service life and wide operating temperature, lithium-ion batteries are widely used in modern society, and the development trend is getting better and better . However, with the continuous development of society, the requirements for the capacity of lithium-ion batteries are also getting higher and higher. The capacity of lithium-ion batteries mainly depends on the capacity of the positive and nega...
