Abstract In this work, a series of Bi10Co16O38 (BCO) micro-sheets have been synthesized at different temperatures through a one-step precipitation method. Furthermore, we have investigated the influence of reaction temperature on the capacitive behavior of BCO based electrodes by electrochemical measurements in 2.0 M KOH electrolyte. The results show that BCO based electrodes display favorable electrochemical performances in the potential range from −0.8 V to 0.4 V. In particular, among BCO electrode materials, BCO-3 electrode materials prepared at 50 °C possess the optimal electrochemical performances with higher specific capacity (932.5 C g−1 at 1.0 A g−1), excellent rate capability (932.5 C g−1 at 1.0 A g−1 and 660.0 C g−1 at 10.0 A g−1) and outstanding cyclic stability even at 7.0 A g−1 after 2000 cycles (up to 83.4% capacity retention). This present work provides a novel electrode material prepared via facile method for highly efficient energy storage.

摘要 在这项工作中，通过一步沉淀法在不同温度下合成了一系列 Bi10Co16O38 (BCO) 微片。此外，我们通过在 2.0 M KOH 电解液中的电化学测量研究了反应温度对基于 BCO 的电极电容行为的影响。结果表明，BCO基电极在-0.8 V至0.4 V的电位范围内表现出良好的电化学性能。特别是，在BCO电极材料中，50 °C制备的BCO-3电极材料具有最佳的电化学性能和更高的比容量（1.0 A g-1 时为 932.5 C g-1），优异的倍率性能（1.0 A g-1 时为 932.5 C g-1，10.0 A g-1 时为 660.0 C g-1），即使在 7.0 A 时也具有出色的循环稳定性g-1 2000 次循环后（容量保持率高达 83.4%）。
