The development of advanced energy storage systems, such as supercapacitors with ideal capacity and durability, is crucial for mitigating intermittency issues associated with natural energy resources. By leveraging the synergistic effects of electrode materials, asymmetric supercapacitors are able to achieve a large voltage window while overcoming traditional supercapacitors' energy storage limitations.
The development of advanced energy storage systems such as supercapacitors with ideal capacity and durability is of major significance to mitigate the intermittency issues associated with natural energy resources, which highly relies on the fabrication of electrode materials with ideal electrochemical properties. By exploiting the superiority of both battery-type and capacitive-type materials, asymmetric supercapacitors can achieve a large voltage window while avoiding electrolyte decomposition, thus addressing the energy storage limitations of traditional supercapacitors. Taking advantage of the synergetic effects of the electrode materials is essential to achieve the optimal overall electrochemical performance in terms of specific capacity, rate capability and durability. Herein, findings and updates in the advanced nickel-based bimetallic battery-type materials are concerned in terms of both the performance and the theoretical mechanism. Meanwhile, synergistic effects between components, including morphological modification, electronic restructuring, surface/interface engineering, and defect construction are critically discussed. Furthermore, major opportunities and challenges on enhancing the electrochemical performance of Nickel-based bimetallic battery-type materials for asymmetric supercapacitors are provided.
