Manufacturing Technology for Vanadium Oxide-Carbon Composite-Based Lithium-Ion Battery Anode Active Material

This technology relates to a vanadium oxide-carbon composite anode active material, its manufacturing method, and a lithium-ion battery comprising the same. Specifically, it is a manufacturing technology for vanadium oxide-carbon composite-based lithium-ion battery anode active material.

In existing technologies, conventional V2O3 material used as an anode active material in lithium-ion batteries presented problems leading to low actual capacity, conductivity, structural stability, and rate capability, which needed to be addressed. Therefore, this technology proposes a configuration that includes a method for manufacturing a V2O3/C composite active material, comprising the steps of dissolving m-ammonium vanadate in a solvent, preparing a precursor, and heat-treating the precursor.

Accordingly, this technology can improve the cycling stability and rate capability of the V2O3/C composite active material, thereby enhancing its performance as an anode active material in lithium-ion batteries. It has application value in the fields of secondary batteries, advanced materials, and chemistry.
