Our use of battery-operated devices and appliances has been increasing steadily, bringing with it the need for safe, efficient, and high-performing power sources. To this end, a type of electrical energy storage device called the supercapacitor has recently begun to be considered as a feasible, and sometimes even better, alternative to conventional widely used energy-storage devices such as Li-ion batteries. Supercapacitors can charge and discharge much more rapidly than conventional batteries and also continue to do so for much longer. This makes them suitable for a range of applications such as regenerative braking in vehicles, wearable electronic devices, and so on. “If a high-performance supercapacitor using a non-flammable, non-toxic, and safe aqueous electrolyte can be created, it can be incorporated into wearable devices and other devices, contributing to a boom in the Internet of Things,” Dr. Takeshi Kondo, who is the lead scientist in a recent breakthrough study in the field, says.
