Studies from University of Waterloo Yield New Data on Applied Materials & Interfaces (All-in-One Graphene Based Composite Fiber: Toward Wearable Supercapacitor)
By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Materials Research - Applied Materials & Interfaces. According to news reporting from Waterloo, Canada, by VerticalNews journalists, research stated, "Graphene fibers (GF) have aroused great interest in wearable electronics applications because of their excellent mechanical flexibility and superior electrical conductivity. Herein, an all-in-one graphene and MnO composite hybrid supercapacitor fiber device has been developed."
Financial support for this research came from Natural Sciences and Engineering Research Council of Canada.
The news correspondents obtained a quote from the research from the University of Waterloo, "The unique coaxial design of this device facilitates large-scale production while avoiding the risk of short circuiting. The core backbone of the device consists of GF that not only provides mechanical stability but also ensures fast electron transfer during charge-discharge. The introduction of a MnO (200 nm in length) hierarchical nanostructured film enhanced the pseudocapacitance dramatically compared to the graphene-only device in part because of the abundant number of active sites in contact with the poly(vinyl alcohol) (PVA)/HPO electrolyte. The entire device exhibits outstanding mechanical strength as well as good electrocapacitive performance with a volumetric capacitance of 29.6 F cm at 2 mv s. The capacitance of the device did not fade under bending from 0? to 150?, while the capacitance retention of 93% was observed after 1000 cycles."
According to the news reporters, the research concluded: "These unique features make this device a promising candidate for applications in wearable fabric supercapacitors."
