The demand for energy storage devices with high energy and power densities has increased tremendously in this rapidly growing world. Conventional capacitors, fuel cells, and lithium-ion batteries have been used as energy storage devices for the long term. However, supercapacitors are one of the most promising energy storage devices because of their high specific capacitance, high power density, and longer cycle life. Recent research has focused on synthesizing transition-metal oxides/hydroxides, carbon materials, and conducting polymers as supercapacitor electrode materials. The performance of supercapacitors can be improved by altering electrolytes, electrode materials, current collectors, experimental temperatures, and film thickness. Thousands of papers on supercapacitors have already been published, reflecting the significance and elucidating how much demanding such energy storage devices for this fast-growing generation. This review aims to illustrate the electrode materials loaded on various conductive substrates by electrochemical deposition employed for supercapacitors to provide broad knowledge on synthetic pathways, which will pave the way for future research. We also discussed the basic parameters involved in supercapacitor studies and the advantages of the electrochemical deposition techniques through literature analysis. Finally, future trends and directions on exploring metals/metal composites toward designing and constructing viable, high-class, and even newly featured flexible energy storage materials, electrodes, and systems are presented.
在这个快速发展的世界中，对具有高能量和功率密度的储能装置的需求急剧增加。传统的电容器、燃料电池和锂离子电池长期以来一直被用作储能装置。然而，超级电容器因其高比电容、高功率密度和更长的循环寿命，是最有前途的储能装置之一。最近的研究集中在合成过渡金属氧化物/氢氧化物、碳材料和导电聚合物作为超级电容器电极材料。通过改变电解质、电极材料、集流体、实验温度和薄膜厚度，可以提高超级电容器的性能。关于超级电容器的数千篇论文已经发表，这反映了其重要性，并阐明了这种储能装置对这个快速发展的时代有多么大的需求。这篇综述旨在阐述通过电化学沉积法负载在各种导电基底上的用于超级电容器的电极材料，以提供关于合成途径的广泛知识，这将为未来的研究铺平道路。我们还通过文献分析讨论了超级电容器研究中涉及的基本参数以及电化学沉积技术的优点。最后，提出了探索金属/金属复合材料以设计和构建可行的、高级的甚至具有新特性的柔性储能材料、电极和系统的未来趋势和方向。
