Hydrothermal synthesis and electrochemical performance of Mn-doped V6O13 as cathode material for lithium-ion battery

MnxV6-xO13 (x = 0.01, 0.02, 0.03, 0.04) were successfully synthesized via a simple hydrothermal method followed by heat-treatment. Both crystal domain size, electronic conductivity and the lithium diffusion coefficient of the MnxV6-xO13 samples were influenced by the doping amount of Mn2+. When x = 0.02, the product was nano-sized particles and exhibited the best electrochemical performance. The enhanced electrochemical performance originated from its higher total conductivity and higher lithium diffusion coefficient.
