摘      要：The Li_(2)ZnTi_(3)O_(8)@Li AlO_(2)was synthesized by a facile high-temperature solid-state *** LiAlO_(2)modification does not alter the morphology and particle size of Li_(2)Zn Ti_(3)O_(8)(LZTO).The LiAlO_(2)modification improves the structure stability,intercalation/deintercalation reversibility of lithium-ions,and electrochemical reaction activity of Li_(2)Zn Ti_(3)O_(8),and promotes the transfer of lithium *** from the unique component,Li_(2)Zn Ti_(3)O_(8)@Li AlO_(2)(8wt%) shows a good rate performance with charge capacities of 203.9,194.8,187.4,180.6,and177.1 mAh·g^(-1)at 0.5,1,2,3,and 5 C,***,pure LZTO only delivers charge capacities of 134.5,109.7,89.4,79.9,and 72.9 mAh·g^(-1)at the corresponding *** at large charge–discharge rate,the Li_(2)Zn Ti_(3)O_(8)@Li AlO_(2)(8wt%) composite indicates a good cycle performance with a high reversible charge/discharge capacity of 263.5/265.8 mAh·g^(-1)at 5 C after 150 *** introduction of LiAlO_(2)on the surface of Li_(2)Zn Ti_(3)O_(8)enhances electronic conductivity of the composite,resulting in the good electrochemical performance of Li_(2)Zn Ti_(3)O_(8)@Li AlO_(2)***_(2)Zn Ti_(3)O_(8)@LiAlO_(2)(8wt%) composite shows a good potential as an anode material for the next generation of high-performance Li-ion batteries.
