Metal Organic Material (MOM) Embedded Electrospun Carbon Nanofiber (CNF) for Symmetric and Asymmetric Supercapacitor

Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)

Structural engineering of two-dimensional (2D) ultrathin metal-organic framework and hierarchical structure of metal- oxide embedded carbon nano fiber are of great significance for energy storage systems. Along with them, the diverse range of Layered Double Hydroxides (LDHs) and their derivatives are also potential electrode materials for supercapacitors. In this project, three different strategies have been employed for developing materials with improved properties for high- performance supercapacitors. The iron-oxide embedded carbon fibre was fabricated through electro-spinning followed by heat-treatment method, exhibited specific capacitance 126 F/g at current density of 1 A/g in the symmetric aqueous device state with good rate capability. The ultrathin LDH and bimetallic metal-organic framework from LDH was developed via in situ hydrothermal process. The LDH derived BMOFs bestowed with capacitance of 549.9 mF/cm2 at a current density of 2 mA/ cm2 in device form.
