Manganese dioxide nanoparticles incorporated within ionic liquid derived fibrillated mesoporous carbon: electrode material for high-performance supercapacitors

Abstract: This article is the first example of the incorporation of metal oxide nanoparticles within ionic liquid derived nano-fibrillated mesoporous carbon (IFMC), as electrode materials for supercapacitor applications. Electron microscopy observations and X-ray diffraction analysis, in addition to gas adsorption/desorption analysis, confirm the incorporation of manganese dioxide within the mesoporous nanofibers (MnO 2 @IFMC) with a high surface area of about 388 m 2 g À1 . MnO 2 @IFMC was successfully employed as a ne… Show more

“…The first class includes carbonaceous materials such as carbon nanotubes, carbon fibers, graphene, and mesoporous carbons which mainly store charges based on the non-faradaic double-layer charge storage or EDLC supercapacitors. Second class of supercapacitor materials are transition-metal oxides/hydroxides (such as MnO 2 , RuO 2 , Co­(OH) 2 , and NiO) and conductive polymers which store the charge via redox reactions occurred at the surface of electrode materials, also called pseudocapacitors. ,, …”

“…Because of the increasing environmental problems, such as global warming and pollution, from fossil-fuel consumption, it is preferable to produce energy from renewable and sustainable resources (e.g., solar and wind). [1][2][3][4][5][6] However, successful exploitation of renewable energy sources requires efficient and reliable energy storage systems. Among all the clean energy technologies, electrochemical energy storage devices such as batteries and supercapacitors are considered as the most feasible, environmentally friendly, and sustainable.…”

“…For EDLCs, charge storage is based on the charge separation at an electrode/electrolyte interface, but pseudocapacitors store charges arising from faradaic reactions at the electrode surface. 3,4,6,7,12 In the last few decades, researchers have focused on the development and enhancement of the capacity and energy density of supercapacitors. Transition metal oxides and hydroxides, such as MnO 2 , Fe 2 O 3 , V 2 O 5 , MoO 3 , NiO, Co 3 O 4 , Ni(OH) 2 , and Co(OH) 2 are promising electrode materials in view of their multiple oxidation states for pseudocapacitor generation.…”
