The Li₂ZnTi_3-xMo_xO₈ (x = 0, 0.05, 0.1 and 0.15) anode materials are successfully synthesized through a simple solid-state method, and few Li₂MoO₄ phase can be found in Li₂ZnTi_3-xMo_xO₈ (x = 0.1 and 0.15). All samples are composed of nanocrystalline particles and irregular micron-sized particles with a relatively uniform particle size of 100–200 nm Li₂ZnTi_2.9Mo_0.1O₈ shows the best electrochemical properties among all samples. The Li₂ZnTi_2.9Mo_0.1O₈ delivers a charge/discharge capacity of 188.1/188.2 mA h/g at 1 A/g after 400 cycles, but the corresponding capacity of pristine Li₂ZnTi₃O₈ is only 104.5 (102.2) mA h/g. The Mo⁶⁺ doping enhances the reversible capacity, rate performance, and cycling stability of Li₂ZnTi₃O₈, especially at large current densities. The improved electrochemical performance of Li₂ZnTi_3-xMo_xO₈ can be ascribed to the enhanced electrical conductivity, improved intercalation/de-intercalation reversibility of Li ions, increased lithium-ion diffusion coefficients, and reduced charge-transfer resistance. This work provides an effective strategy to construct high-performance anode materials for advanced lithium-ion battery; this effective design strategy may be used to enhance the reversible specific capacity, and rate the performance and cycle stability of other insertion-host anode materials.

 通过简单的固态方法成功合成了Li ₂ ZnTi _{3- x} Mo _x O ₈ ( x = 0, 0.05, 0.1 and 0.15)负极材料，Li ₂ ZnTi _{3 中}几乎没有Li ₂ MoO ₄相_{- x} Mo _x O ₈ ( x  = 0.1 和 0.15)。所有样品均由纳米晶颗粒和不规则的微米级颗粒组成，粒径相对均匀，为 100–200 nm Li ₂ ZnTi _2.9 Mo _0.1 O ₈在所有样品中显示出最好的电化学性能。Li ₂ ZnTi _2.9 Mo _0.1 O ₈在 1 A/g 循环 400 次后提供 188.1/188.2 mA h/g 的充电/放电容量，但原始 Li ₂ ZnTi ₃ O ₈的相应容量仅为 104.5 (102.2)毫安小时/克。Mo ⁶⁺掺杂增强了Li ₂ ZnTi ₃ O ₈的可逆容量、倍率性能和循环稳定性，尤其是在大电流密度下。Li ₂ ZnTi _{3- x} Mo _x O ₈电化学性能的改善可归因于增强的导电性、改善的锂离子嵌入/脱嵌可逆性、增加的锂离子扩散系数和降低的电荷转移电阻。这项工作为构建用于先进锂离子电池的高性能负极材料提供了一种有效的策略；这种有效的设计策略可用于提高可逆比容量，并评估其他插入主体负极材料的性能和循环稳定性。
