Available in PDF, EPUB and Kindle. Book excerpt: Supercapacitors, also known as electrochemical capacitors or ultracapacitors, have been playing an ever increasing important role in bridging the performance gap between electrolytic capacitors and batteries since their inception in the 1960s. Either working as an independent power source or as a complement for batteries, therefore, supercapacitors have been indispensable in a number of applications due to their extraordinary high power density and fit-and-forget benefit. More recently, with the increasing awareness of their performance characteristics, supercapacitors are finding their way to more applicable niche markets. As the major working medium inside supercapacitors, high surface area activated carbon is dominating current commercial supercapacitors. Over the past decades, major advances have occurred in both understanding and improving the electrochemical performance of supercapacitors. In this work, some novel porous carbon nanostructures have been investigated as a substitute or performance enhancer for activated carbon inside supercapacitors. Moreover, we also summarized the inconsistencies for supercapacitors performance evaluation and provided some possible solutions. Chapter 1 provided a general overview of the basic working principle of supercapacitors and their constituting components (aka electrode, electrolyte, separator, current collector and additives). Chapter 2 presented a novel electrode fabrication method, named vacuum filtration deposition, to produce graphene-based supercapacitor electrodes. This vacuum filtration deposition method greatly improved the mass loading of graphene-based supercapacitor electrodes and therefore increased their energy storage ability. Chapter 3 discussed the effect of graphene morphology on the electrochemical performance of resulting supercapacitor electrodes. We concluded that crumpled graphene is favorable in supercapacitor applications compared to their planar counterpart. Chapter 4 demonstrated the performance enhancement of conventional activated carbon based supercapacitor upon graphene addition. 50 % increase in power density was concluded, which might have profound practical impact to the industry. Chapter 5 summarized some of the inconsistencies we encountered for the evaluation of supercapacitors, which severely hindered effective communication in the field. We clarified those inconsistencies and proposed some approaches to mediate this issue. Chapter 6 recapped the major conclusions from our study and listed some possible future work.

Download or read book Synthesis Characterization and Application of Hollow Carbon Nanostructures written by Yian Song and published by . This book was released on 2016 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes fundamental studies of hollow carbon nanostructures, which may be used as electrodes for practical energy storage applications such as batteries or supercapacitors. Electron microscopy is heavily utilized for the nanoscale characterization. To control the morphology of hollow carbon nanostructures, ZnO nanowires serve as sacrificial templates. The first part of this dissertation focuses on the optimization of synthesis parameters and the scale-up production of ZnO nanowires by vapor transport method. Uniform ZnO nanowires with 40 nm width can be produced by using 1100 °C reaction temperature and 20 sccm oxygen flow rate, which are the two most important parameters.The use of ethanol as carbon source with or without water steam provides uniform carbonaceous deposition on ZnO nanowire templates. The amount of as-deposited carbonaceous material can be controlled by reaction temperature and reaction time. Due to the catalytic property of ZnO surface, the thicknesses of carbonaceous layers are typically in nanometers. Different methods to remove the ZnO templates are explored, of which hydrogen reduction at temperatures higher than 700 °C is most efficient. The ZnO templates can also be removed under ethanol environment, but the temperatures need to be higher than 850 °C for practical use.Characterizations of hollow carbon nanofibers show that the hollow carbon nanostructures have a high specific surface area (>1100 m2/g) with the presence of mesopores (~3.5 nm). The initial data on energy storage as electrodes of electrochemical double layer capacitors show that high specific capacitance (> 220 F/g) can be obtained, which is related to the high surface area and unique porous hollow structure with a thin wall.
