Title:
GLASS NEGATIVE ELECTRODE MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087415
Kind Code:
A1
Abstract:
The present invention provides a glass negative electrode material, prepared from the following raw materials in parts by weight: 0.1-50 parts of Co3O4, 5-60 parts of TiO2, 1-60 parts of Ta2O5, 15-60 parts of ZnO, 3-60 parts of V2O5, and 10-40 parts of TeO2. According to the present invention, for the problems of a low first-cycle specific capacity, low conductivity, and poor cycle stability of a vanadium-tellurium glass material as a lithium ion electrode material, transition metal oxides cobalt oxide and zinc oxide each having a high specific capacity and titanium oxide having a high electron transport property are added to improve the capacity and the cycle stability. The present invention provides a glass material which is high in first-cycle specific capacity and good in cycle stability. The present invention further provides a preparation method for the glass negative electrode material and the use of the glass negative electrode material.
