The effect of mechanical activation in a BM6 Pro planetary mill on the synthesis and electrochemical properties of lithium vanadium phosphate is studied. It is found that the optimal rate and time of mechanical activation are 500 rpm and 40 min, respectively. The initial discharge capacity of the electrodes based on synthesized lithium vanadium phosphate is 136 mA h g–1 at a current of 0.2 C and 112 mA h g–1 at a current of 1.0 C. The electrodes retain high electrochemical reversibility and structural stability in this range of discharge currents.
