Arrays of CuO nanostructures, including nanorods and nanosheets, supported on a Cu substrate have been rationally fabricated from their morphology-controlled Cu(2)(OH)(3)NO(3) precursors by thermal annealing. The as-prepared CuO samples can be directly used as integrated electrodes for lithium-ion batteries without the addition of other ancillary materials such as carbon black or a binder to enhance electrode conductivity and cycling stability. The unique nanostructural features endower them excellent electrochemical performance as demonstrated by high capacities of 450-650 mAh g(-1) at 0.5-2 C and almost 100% capacity retention over 100 cycles after the second cycle.
已经通过热退火，从其形态可控的 Cu(2)(OH)(3)NO(3)前体中合理地制备了在 Cu 基底上的 CuO 纳米结构阵列，包括纳米棒和纳米片。无需添加其他辅助材料（如炭黑或粘结剂）来提高电极导电性和循环稳定性，所制备的 CuO 样品可以直接用作锂离子电池的集成电极。独特的纳米结构特征使它们具有出色的电化学性能，例如在 0.5-2 C 的电流密度下具有 450-650 mAh g(-1)的高容量，并且在第二次循环后经过 100 次循环后容量保持率几乎为 100%。
