Solvothermal synthesis and electrochemical performance of Ag-doped V6O13 as cathode material for lithium-ion battery

For the first time, belt-like V6O13 precursor was synthesized via a simple solvothermal method. Rod-like Ag-doped V6O13 was successfully synthesized by this method followed by heating at 350 A degrees C. Both crystal domain size, electronic conductivity, and the lithium diffusion coefficient of the Ag-doped V6O13 samples are influenced by the added amount of AgNO3. When the amount of AgNO3 is 0.008 g, the product is rod-like particles, which are 0.1-0.3 mu m wide and 1-2 mu m long, and exhibits the best electrochemical performance. The enhanced electrochemical performance originates from its higher total conductivity, higher lithium diffusion coefficient, and better structural reversibility.
