Advances in nickel-based metal-organic framework (MOF) electrode materials for supercapacitors and their impact on energy management in computer and artificial intelligence systems

This review summarizes the latest advancements in nickel-based metal-organic framework (Ni-MOF) electrode materials for supercapacitors and discusses their impact on energy management in computer and artificial intelligence (AI) systems. It highlights a significant breakthrough in directly growing binder-free MOFs on nickel foam substrates, which enhances the conductivity and stability of the electrodes by eliminating the need for additional binders, thereby improving energy density and power output. Furthermore, the article explores a diverse range of materials prepared from Ni-MOF precursors, including Ni-based oxides/hydroxides, sulfides, phosphides, and carbides, which exhibit tailored electrochemical properties and cycling stability. These materials provide unique design opportunities for supercapacitors to meet the stringent requirements of modern computing architectures, such as edge computing devices, AI accelerators, and high-performance computing clusters. This review not only emphasizes the potential of Ni-MOFs in achieving high-performance supercapacitors but also points out their adaptability to a wide range of electrochemical conditions, making them ideal candidate materials for applications where energy density, cycle life, and operating temperature range are critical.
