Researchers are trying to find a novel anode material which is essential for taking lithium batteries to the next stage. Among the classical anodes, the conversion electrodes play a special role owing to their capability to provide a higher initial discharge capacity than the theoretical capacity. In this string, a new brannerite type copper vanadate conversion anode makes its impression in the lithium battery world. A poor capacity retention and voltage hysteresis exhibited by the typical conversion anode is the main obstruction to commercialize it for lithium batteries. But in the present work, a brannerite type copper vanadium oxide prepared by hydrothermal method has been used as a conversion anode for lithium batteries with approximately 100 % columbic efficiency and 70 % capacity retention. The low voltage hysteresis, better capacity retention, excellent columbic efficiency and better cyclability will make this material as a better choice to replace the conventional anode for lithium batteries in future.
