ZrO2 coated Li1.9K0.1ZnTi3O8 as an anode material for high-performance lithium-ion batteries

Abstract

The Li1.9K0.1ZnTi3O8@ZrO2 (1 wt%, 3 wt%, and 5 wt%) anode material was synthesized by doping Li2ZnTi3O8 with potassium and coating ZrO2, where the ZrO2 coating layer was prepared by citric acid and zirconium acetate, and the potassium source was KCl. When the added ZrO2 amount is 3%, the material has the most uniform size, reduced polarization, and reduced charge transfer resistance, and the specific capacity of LKZTO@ZrO2 (3 w%) was 361.5 mA h g−1 at 200 mA g−1 at the 100th cycle, which is higher than that of LKZTO, of 311.3 mA h g−1. The specific capacities of LKZTO@ZrO2 (3 w%) at 50, 100, 200, 500, and 1000 mA g−1 after 10 cycles were 424.9, 410.7, 394.1, 337.6 and 270.6 mA h g−1, indicating that LKZTO@ZrO2 (3 w%) has excellent electrochemical performance.
