The study of zirconium vanadate as a cathode material for lithium ion batteries

The electrochemical properties of ZrV(2)O(7) (ZVO) and ZVO@C were investigated in lithium ion batteries. The first charge (or discharge) specific capacity of ZVO and ZVO@C are 279 mA h g(−1), 392 mA h g(−1), 208 mA h g(−1) and 180 mA h g(−1) for 0%, 3%, 5% and 9% of carbon, respectively. The capacit...

Sumario:The electrochemical properties of ZrV(2)O(7) (ZVO) and ZVO@C were investigated in lithium ion batteries. The first charge (or discharge) specific capacity of ZVO and ZVO@C are 279 mA h g(−1), 392 mA h g(−1), 208 mA h g(−1) and 180 mA h g(−1) for 0%, 3%, 5% and 9% of carbon, respectively. The capacity retention rates (with 0% 3%, 5% and 9% carbon content) are 33.0%, 52.5%, 56.4% and 76.1% after ten cycles, respectively. The low inner resistance relates to the good contact of the electrode rather than the high content of carbon, and the specific capacity retention rate increases with the increase of the carbon content.
