As one of the most promising energy storage devices, supercapacitors exhibit a higher power density than batteries. However, its low energy density usually requires high-performance electrode materials. Although the RuO material shows desirable properties, its high cost and toxicity significantly limit its application in supercapacitors. Recent developments demonstrated that Co-based materials have emerged as a promising alternative to RuO for supercapacitors due to their low cost, favorable redox reversibility and environmental friendliness. In this paper, the morphological control and performance engineering of Co-based materials are systematically reviewed. Firstly, the principle of supercapacitors is briefly introduced, and the characteristics and advantages of pseudocapacitors are emphasized. The special forms of cobalt-based materials are introduced, including 1D, 2D and 3D nanomaterials. After that, the ways to enhance the properties of cobalt-based materials are discussed, including adding conductive materials, constructing heterostructures and doping heteroatoms. Particularly, the influence of morphological control and modification methods on the electrochemical performances of materials is highlighted. Finally, the application prospect and development direction of Co-based materials are proposed.
作为最具前景的储能装置之一，超级电容器展现出比电池更高的功率密度。然而，其低能量密度通常需要高性能的电极材料。尽管RuO材料表现出理想的性能，但其高成本和毒性显著限制了它在超级电容器中的应用。最近的进展表明，钴基材料因其低成本、良好的氧化还原可逆性和环境友好性，已成为超级电容器中RuO的一种有前景的替代材料。本文系统地综述了钴基材料的形态控制和性能工程。首先，简要介绍了超级电容器的原理，并强调了赝电容器的特点和优势。介绍了钴基材料的特殊形式，包括一维、二维和三维纳米材料。之后，讨论了增强钴基材料性能的方法，包括添加导电材料、构建异质结构和掺杂杂原子。特别强调了形态控制和改性方法对材料电化学性能的影响。最后，提出了钴基材料的应用前景和发展方向。
