Use of Vanadium-Containing Slime for Preparing Cathodes for Lithium-Ion Current Sources
- 2 Downloads
Crude vanadium-containing dump slimes can be used as a raw material for preparing lithium vanadium oxides suitable as cathode materials for lithium-ion chemical current sources. A simple procedure for preparing LiV3O8 from the slime was suggested. The synthesized compound was characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and synchronous thermal analysis. The material prepared from vanadium-containing dump slimes has uniform microstructure and high electronic conductivity of the order of 1.4 × 10–2 S cm–1; it is thermally stable in the interval 30–550°С and capable of intercalation/deintercalation of lithium ions in its structure in the course of cycling in lithium-ion current sources.
