Abstract A simple, green, cheap and scalable approach to fabricate nickel oxides materials has been developed in this work. The synthesis was via a facile two-step route, the nickel hydroxide is obtained by hydrothermal synthesis and then this precipitate is calcined. The prepared compounds are used as anode material for lithium-ion batteries. These electrodes deliver specific discharge capacity values of the order of 500 mAh g-1 for a C-rate of 0.2C. They remain at 78% of their initial capacity after 100 cycles and exhibit a satisfactory rate performance as well as cycling stability. These electrochemical properties are correlated with their kinetic parameters.

氧化镍作为锂离子电池负极的合成及电化学性能

摘要 这项工作开发了一种简单、绿色、廉价且可扩展的方法来制造氧化镍材料。该合成是通过简单的两步路线,通过水热合成获得氢氧化镍,然后将该沉淀物煅烧。制备的化合物用作锂离子电池的负极材料。对于 0.2C 的 C 倍率,这些电极提供大约 500 mAh g-1 的特定放电容量值。它们在 100 次循环后仍保持其初始容量的 78%,并表现出令人满意的倍率性能和循环稳定性。这些电化学性质与其动力学参数相关。
