Book excerpt: Developing novel functional materials for applications in energy storage and conservation is essential to solving today's problems of meeting growing energy demands with minimal environmental impact. The first part of this dissertation describes pseudocapacitive Li-ion electrodes for fast charge storage. Pseudocapacitance, a charge-transfer process that is not diffusion-limited by definition, can be achieved by utilizing short diffusion lengths in nanostructures. In this section, three distinct transitional metal oxides with nanoscale architecture, Nb2O5, MoO2, and LiMn2O4, are examined. We focus on correlating charge storage mechanisms with structural properties, and exploring different aspects of pseudocapacitive charge storage with each system. First, we developed a core/shell Nb2O5/Nb4N5 composite via partial nitridation, achieving specific capacity over 500 C/g within 90 seconds. Our use of the nitride shell provides excellent electronic pathways that connect Nb2O5 nanoparticles and improve the interfacial electrical conductivity. The charge storage mechanism was found to depend on the thickness of the nitride shell. For MoO2, we developed an interconnected porous network that provides facile electrical and ionic pathways for fast charge storage. We also used it as a model system to understand the effects of structural variations on charge storage behavior. Phase transition suppression was found to be associated with highly capacitive systems, and a strong correlation between charge storage properties and crystallite size was established. Last, we developed needle-like nanostructures with selectively engineered surface facets to overcome its capacity loss due to surface Mn dissolution. This unique structure allowed for a higher capacity and less surface Mn dissolution due to a dominant presence of dissolution-resistant facets. The second part of this dissertation studies thermal transport in mesoporous SiO2. SiO2 is widely used in many thermal insulating applications due to its facile synthesis and easy-to-control of structure. Porous amorphous SiO2 has strong boundary scattering effects that lead to significantly low thermal conductivity. In this section, we examined the effect of porosity, pore size, and framework texture (i.e., continuous or nanoparticulate) on thermal conductivity in mesoporous SiO2 thin films. Sol-gel and nanoparticle-based mesoporous SiO2 thin films were synthesized by evaporation-induced self-assembly using tetraethyl orthosilicate and pre-made SiO2 nanoparticles as the framework precursors, respectively, and a variety of template reagents. The thermal conductivity was measured by time-domain thermoreflectance at room temperature in vacuum. A porosity weighted simple effective medium approximation was employed to explain trends in thermal conductivity. The results give new insight into thermal transport in nanostructured amorphous materials, and suggest design rules of the nanoscale architecture to control the thermal conductivity of mesoporous materials for a wide range of applications.

This book was released on 2016 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing functional materials for advanced energy applications is a critical step in minimizing our use of fossil fuels for energy. The first part of this dissertation describes pseudocapacitive energy storage materials for fast charge storage applications. In this section, nanostructured transition metal oxides and sulfides are examined as attractive pseudocapacitive materials. These materials discussed in this dissertation show the hallmarks of pseudocapacitors, and consistently delivered more than 100 mAh/g at 100C (~30 seconds) and thousands of (dis)charge cycles. Synchrotron operando X-ray diffraction studies of these materials establish a clear structural charge storage mechanism that is responsible for the extremely fast kinetics and long lifetimes. We specifically focus on the idea that in most battery materials, distinct phase transitions occur between lithiated and non-lithiated states, and phase transition kinetics can dominate the kinetics of Li+ intercalation. We show that a key component of intercalation pseudocapacitance is suppression of such phase transitions in nanostructured materials. The second part of this work describes Li-alloying negative electrodes, which are attractive candidates to replace graphite in Li-ion batteries because of their high energy densities. However, charge storage in these materials is accompanied by a large volume change which pulverizes the particles, leading to electrode failure To addresses these problems, two scalable solution based synthetic methodologies will be discussed to synthesize nanoporous tin and silicon that show long cycle-lifetimes. This work specifically employs synchrotron operando transmission X-ray microscopy to directly examine structural changes of single tin particles during cycling to show how structure, morphology, and size modify the fundamental storage mechanisms in nanostructured tin. The third section of this work describes our work on a high performance nanostructured porous NiFe-based oxygen evolution catalyst made by selective alloy corrosion. A major challenge is developing oxygen-evolving catalysts that are inexpensive, highly corrosion-resistant, and able to oxidize water at high current densities and low overpotentials. A practical NiFe-based catalyst was developed with high surface area, and therefore, a high density of oxygen-evolution catalytic sites per unit mass leading to unprecedented performance.
