Electrochemical performance of ZnO-coated Li(4)Ti(5)O(12) composite electrodes for lithium-ion batteries with the voltage ranging from 3 to 0.01 V

Oxide is widely used in modifying cathode and anode materials for lithium-ion batteries. In this work, a facile method of radio magnetron sputtering is introduced to deposit a thin film on Li(4)Ti(5)O(12) composite electrodes. The pristine and modified Li(4)Ti(5)O(12) electrodes are characterized at...

description Oxide is widely used in modifying cathode and anode materials for lithium-ion batteries. In this work, a facile method of radio magnetron sputtering is introduced to deposit a thin film on Li(4)Ti(5)O(12) composite electrodes. The pristine and modified Li(4)Ti(5)O(12) electrodes are characterized at an extended voltage range of 3–0.01 V. The reversible capacity reaches a high level of 286 mAh g(−1), which is a little less than its theoretical capacity (293 mAh g(−1)). Electrodes modified by ZnO thin films with various thickness show elevated rate capability and improved cycle performance.
