Download Science, Technology and Advanced Application of Supercapacitors Book in PDF, ePub and Kindle
Application fields of supercapacitors are expanding because they have a very large charge/discharge current density and a cycle durability of tens of thousands of cycles or more compared to secondary batteries. There are various kinds of supercapacitor: electric double layer capacitors with a relatively long history, pseudocapacitors that utilize electrochemical reactions, and the progress of hybrid capacitor technology that combines double layer capacity and electrochemical reactions. Development of electrode materials and electrolytes and new cell design for constructing devices support the performance improvement and expansion of new applied fields such as automobiles, heavy machinery, and energy harvesting. This book aims to provide engineers with the opportunity to review the latest information by integrating cutting-edge papers on science, technology, and the application of supercapacitors.

Download Lithium-ion Battery Anodes of Randomly Dispersed Carbon Nanotubes, Nanofibers, and Tin-oxide Nanoparticles Book in PDF, ePub and Kindle
Lithium-ion battery anodes with a nanostructure of randomly dispersed carbon nanofibers (CNFs), carbon nanotubes (CNTs), and nanoparticles of tin-oxide or silicon were fabricated and tested in order to develop high capacity, easily manufactured anodes. In these anodes, a mesh of CNTs and CNFs form a conductive network within which the nanoparticles of tin-oxide are suspended. The CNT network directs electron flow to and from the nanoparticles while accommodating their volume changes. The CNFs were intended to aid electron transport by serving as conduction channels between the CNTs and the current collector. Secondarily, the CNFs reinforce the physical structure of the anodes. The nanostructure of the anodes allows the electrolyte to freely penetrate, facilitating ionic transport. In most cases, the components of the anode were held together by Van der Waals forces. Both single-walled carbon nanotubes and multi-walled carbon nanotubes were used in this study in order to determine if there performance would be similar. The anodes take advantage of the specific capacity of tin and tin-oxide, which are 981 mAh/g and 1,491 mAh/g, respectively. Because tin is known to expand to three times its original size when it alloys with lithium, it is used in nanoparticle form for these anodes and thus avoids the tendency of tin to disintegrate. To achieve the desired nanostructure, processing methods based on buckypaper formation were explored. Sonication processes were experimented with to determine the optimum conditions for the fabrication of the anodes. Additionally, additives to aid in the binding of the tin-oxide nanoparticles to the CNTs were explored. These included the addition of polyvinylidene fluoride (PVDF) or carbonized phenolic resins. Anodes were found to exhibit the highest reversible capacity when the processing times were kept to a minimum. This was most likely due to the tendency of CNTs to shorten when sonicated. The shorter sonication times were sufficient to allow the desired level of entrapment of the tin-oxide nanoparticles by the CNTs without degrading the physical characteristics of the CNTs. While the CNTs were intended to move with the tin-oxide nanoparticles and maintain electrical contact as they expanded and contracted, it was discovered that a film of electrolyte-based material formed on the nanoparticles, CNTs, and CNFs, disrupting the current flow. A mechanistic model was developed to illustrate the internal degradation of the anodes. Resistance and reversible capacity prediction models were also developed. The resistance prediction model was used to confirm the effect of the CNFs on the electrical characteristics of the anodes. As its name implies, the reversible capacity prediction model can be used in future endeavors to predict the reversible capacity that may be obtained in buckypaper anodes with various percentages of constituents and processing times.

Download Synthesis and Characterization of Carbon Nanotube Modified Electrode Materials for Li-ion Batteries Book in PDF, ePub and Kindle
Today, the Lithium ion (Li-ion) is the fastest growing and most promising rechargeable battery chemistry. For high current demands, there is an emphasis on the importance of very low cell resistance to allow unrestricted flow of current. The electrochemical performance of Li-ion batteries relies significantly on the properties of the cathode materials, the anode materials and the electrolytes. In this study, novel anode and cathode materials were synthesized and systematically studied for Li-ion battery application. Novel anode synthesis involved the substitution of the flat foil current collectors normally used by nano- or micro-wire arrays, as the higher surface area makes it possible to pack much more active material into an electrode. Ni or Cu wire arrays with wire thicknesses of 200 nm, 400 nm or 1 \03BCm were synthesised. Carbon nanotubes (CNTs) were chosen as the Li-insertion compound due to its high theoretical reversible lithium storage capacity. Synthesis of the Cu or Ni/CNT consolidated composite anodes were done using novel synthetic techniques, combining template synthesis via electrochemical deposition and chemical vapour deposition (CVD) techniques. XRD analysis of both the Ni and Cu wire arrays after carbon nanotube deposition, confirmed that the crystallinity of the wire arrays were not altered by the CVD of carbon nanotubes. The optimal results were obtained for the 200 nm Cu/CNT consolidated composite anode. The current density obtained for the Li de-intercalation (\03AFp) was 0.463 A/g. A reversible discharge capacity of 358 mAh/g was obtained in the subsequent charge/discharge cycling. The composite anode materials showed good charge/discharge cycling performances and a high capacity integrity was maintained in the cycling behaviour analyses.
