Sodium-ion supercapacitor

Sodium-ion supercapacitors are the new type of hybrid capacitor that is a fast-growing storage device which is evolved as an alternative to lithium-ion storage devices. Material design and cell constructions make these devices grow fast. We mainly study sodium-based phosphate with morphology tuning and electrolyte modifications. These devices were found to be more stable under non-ambient conditions like elevated temperatures, external magnetic field and external mechanical vibrations.
