In a world where the ever-changing advancements in technology demand for different forms of energy storage, the potential utilization of supercapacitors in the near future can be extensive if research breakthroughs are achieved. In addition, the increasingly mobilized world demands for more compact gadgets that require higher specific power and energy than conventional rechargeable batteries and supercapacitors have the potential to cater to these needs. Due to the supercapacitor’s energy density limitations, they are currently limited to applications like temporary energy storage, short duration peak power boost and quick short-term power backup in uninterruptable power supply applications. All these help complement the primary power supply, which in most cases, is the battery by increasing its lifespan or being able to downsize these batteries. Therefore, there is a need for research to focus on developing material systems that can provide the high energy densities required for supercapacitors to be utilized in a broader spectrum of applications. This report seeks to ascertain the potential electrochemical capabilities of nickel and cobalt material systems and address this problem that supercapacitors have been facing.
