METHOD FOR MANUFACTURING OF CATHODE MATERIAL, CATHODE MATERIAL AND LITHIUM-ION CELL Russian patent published in 2016 - IPC H01M4/48 H01M4/583 H01M10/38 B82Y30/00 

FIELD: electricity.

SUBSTANCE: procedure consists of following stages: obtainment of hydrogel or xerogel V₂O₅; exposure in sealed Teflon autoclave at temperature of 130-200°C and pressure of 100-600 MPa during twenty four hours of the mix containing hydrogel or xerogel V₂O₅, and carbon material with obtainment of composite material containing nanorods V₂O₅ in graphene shell; centrifugal separation of composite material; washing of composite material; drying of composite material at temperature of 50°C. Composite cathode material and lithium cell are suggested also.

EFFECT: invention allows increase in capacitance and number of recharge cycles of the cell.
