In this paper, for the first time, we report the synthesis of nanoscale cuprous chloride (CuCl) cubic structure by a facile hydrothermal route. A possible mechanism for the growth of those nanostructures is proposed based on the experimental results. It is discovered that the existence of HCl could affect the surface of CuCl nanocubes. This unique cube-like nanostructure with rough surface significantly enhances the electroactive surface areas of CuCl, leading to a high special capacitance of 376 mF cm at the current density of 1.0 mA cm. There is still a good reversibility with cycling efficiency of 88.8 % after 2,000 cycles, demonstrating its excellent long-term cycling stability and might be the promising candidates as the excellent electrode material.
在本文中，我们首次报道了通过简便的水热法合成纳米级氯化亚铜（CuCl）立方结构。基于实验结果提出了这些纳米结构生长的可能机制。发现HCl的存在会影响CuCl纳米立方体的表面。这种具有粗糙表面的独特立方状纳米结构显著提高了CuCl的电活性表面积，在电流密度为1.0 mA/cm²时导致高达376 mF/cm²的比电容。在2000次循环后仍具有良好的可逆性，循环效率为88.8%，证明了其优异的长期循环稳定性，可能是作为优异电极材料的有前途的候选者。
