Supercapacitors as one of the most promising energy storage systems have been extensively studied due to the unique merits such as long-term cycling stability, fast charge rate, and low maintenance cost. It is widely known that the electrochemical performances of supercapacitors are closely related to the structure and specific surface area of the electrode materials. Therefore, many researches are focused on the design and synthesis of the electrode materials with novel shapes and large surface area. CuCo2O4 has recently attracted enormous research interests as the electrode materials for supercapacitors owing to its inherent advantages including high theoretical capacity, environmental friendliness, natural abundance, and low cost. In the practical applications the CuCo2O4 still suffers from some drawbacks, for instance, poor conductivity, relatively low specific capacity, and poor cycling durability. Hence, a comprehensive summary about the recent progress of CuCo2O4-based materials is necessary and significant to better understand the opportunity and challenge that such material faces. In this work, the progress of preparation methods and electrochemical performances of CuCo2O4-based materials is comprehensively reviewed. The aim of this review is to highlight some of the advances made by CuCo2O4-based electrode materials for supercapacitors and guide future research toward closing the gap between achieved and theoretical capacity, without limiting the loading mass.
