Abstract

With the industrial revolution in electronics, the demand for lithium-ion batteries, particularly those designed for electric vehicles and energy storage systems, has accelerated in recent years. This continuously increasing demand requires high-performance electrode materials, as commonly used graphite anodes show limited lithium intercalation. In this context, Ni-substituted ZnCoO nanostructures, thanks to their high storage capacity, have potential for use as an anode material in lithium-ion batteries. Structural analysis concludes that the prepared materials show improved crystallinity with increasing Ni at the Zn-site in ZnCoO. The intermediate composition, ZnNiCoO, of this series exhibits a specific capacity of 65 mA h g at an elevated current rate of 10 A g. The lithium insertion/extraction mechanism is investigated cyclic voltammetry, showing two redox peaks from ZnCoO and a single redox peak from NiCoO. Additionally, the lithium diffusion coefficient in the prepared electrodes is computed to be 2.22 × 10 cm s for the intermediate composition, as obtained using cyclic voltammetry. Electrochemical impedance spectroscopy is used to observe the charge transport mechanism and the charge transfer resistance values of all the samples, which are calculated to be in the range of 235 to 306 Ω.

摘要

随着电子工业革命的发展，近年来对锂离子电池的需求加速增长，尤其是那些为电动汽车和储能系统设计的电池。这种持续增长的需求需要高性能的电极材料，因为常用的石墨阳极显示出有限的锂嵌入能力。在这种背景下，镍取代的ZnCoO纳米结构由于其高存储容量，有潜力用作锂离子电池的阳极材料。结构分析得出结论，所制备的材料随着ZnCoO中锌位点处镍含量的增加，结晶度得到改善。该系列的中间组成ZnNiCoO在10 A g的高电流速率下表现出65 mA h g的比容量。通过循环伏安法研究锂嵌入/脱出机制，结果表明ZnCoO有两个氧化还原峰，NiCoO有一个氧化还原峰。此外，使用循环伏安法得到的中间组成的制备电极中的锂扩散系数计算为2.22×10 cm² s⁻¹。利用电化学阻抗谱观察所有样品的电荷传输机制和电荷转移电阻值，计算得出其范围在235至306 Ω之间。
