    In modern era, there is a dire need to design a hybrid energy storage device showing properties of both supercapacitors and batteries. No doubt, various electrode materials have claimed their efficiency but metal organic frameworks (MOFs) have been focused significantly due to their salient features like high porosity and unique electrochemical properties. In this article, we report cerium-based 3D MOF having rectangular microspore sizes 0.27 x 0.52 nm for rapid and selective transport of charges to be used in hybrid energy storage devices. Structural elucidation was carried out thought single-crystal X-ray diffraction (XRD) spectroscopy and electrochemical attributes were delved via different electroanalytical tools. Three-electrode assembly in 1 M KOH electrolyte unearthed efficiency of the synthesized material and practical applications were divulged through two-electrode assembly by fabricated hybrid device. Diffusive and capacitive contribution of the material was investigated by Dunn's method. The hybrid device showed specific capacityof 101.3 C/g, specific energy of 21.11 Wh/kg and specific power of 1237.78 W/kg with cyclic stability of 99 % even after 5000 GCD cycles. Significant results proved that the material is a prospective contender for futuristic hybrid supercapacitors.
