Battery-type electrode materials such as Ni(OH)2 applied in Faraday supercapacitors could present a low cycling stability due to the microstructure damage of materials, originating from their cyclic volume swelling and shrinking. It is well established that the structural stability of materials is crucial for their cycling stability. However, the lack of knowledge about the structural relevance of materials to their cycling stability somehow results in a chaotic understanding on the material design. In this study, we try to reveal the structural relevance by comparing an orderly built nanostructure with a randomly packed nanostructure using Ni(OH)2 as the target material. It is found that the branched nanosheet-interlaced nanostructure of Ni(OH)2 has its self-supportive function in favor of its structural stability, thus promoting its cycling stability. Also, the orderly nanostructured Ni(OH)2 presents high electrochemical performance due to the reduced interfacial charge-transfer resistance and Warburg resistance.

衍生自同构Ni3（NO3）2（OH）4的高性能Ni（OH）2的分支纳米片交错结构，以阐明结构自支撑在循环稳定性中的作用
法拉第超级电容器中使用的电池型电极材料（例如Ni（OH）2）由于材料的微观结构破坏（由于其循环体积膨胀和收缩）而可能表现出较低的循环稳定性。众所周知，材料的结构稳定性对其循环稳定性至关重要。但是，缺乏有关材料与其循环稳定性的结构相关性的知识，导致对材料设计的混乱理解。在这项研究中，我们试图通过比较有序构建的纳米结构与使用Ni（OH）2作为目标材料的随机堆积的纳米结构来揭示结构相关性。发现Ni（OH）2的支化纳米片交错的纳米结构具有自支撑功能，有利于其结构稳定性，从而提高其循环稳定性。而且，由于降低的界面电荷转移电阻和Warburg电阻，有序的纳米结构的Ni（OH）2具有较高的电化学性能。
