Abstract Zn2SnO4-carbon cloth, prepared via the coherent growth of Zn2SnO4 on pre-functionalized carbon cloth, was employed as a freestanding and binder-free anode for lithium-ion batteries. The 2D Zn2SnO4 nano-plates were uniformly anchored on the surface of 1D carbon cloth to form a hierarchical structure, providing the fast Li-ion and electron exchange path and reducing the volume change during the Li-ion planting/stripping. The binder-free electrode delivered significantly enhanced electrochemical performance by maintaining a reversible capacity of 1510 mA h/g after 60 discharge-charge cycles at a current density of 100 mA/g compared with that of the Zn2SnO4. Systematic structural and electrochemical characterizations suggested that the synergistic effect between Zn2SnO4 nanoplates and carbon cloth was responsible for the high electrochemical performance. Therefore, this study would be of significance for promoting the application of binary transition metal oxides in lithium-ion batteries.

用于高性能锂离子电池的Zn 2 SnO 4 -碳布独立柔性阳极

摘要 Zn2SnO4-碳布是通过在预功能化碳布上连贯生长 Zn2SnO4 制备的，可用作锂离子电池的独立无粘合剂负极。二维 Zn2SnO4 纳米片均匀锚定在一维碳布表面形成分层结构，提供快速的锂离子和电子交换路径，减少锂离子植入/剥离过程中的体积变化。与 Zn2SnO4 相比，无粘合剂电极在 100 mA/g 的电流密度下，在 60 次放电-充电循环后仍保持 1510 mA h/g 的可逆容量，从而显着提高了电化学性能。系统的结构和电化学表征表明，Zn2SnO4 纳米片和碳布之间的协同效应是高电化学性能的原因。因此，本研究对推动二元过渡金属氧化物在锂离子电池中的应用具有重要意义。
