1. Li, Mengya. Nanomanufacturing of Carbon Nanocomposites for Energy Storage and Environmental Applications.

Degree: PhD, Mechanical Engineering, 2018, Vanderbilt University

Carbon nanomaterials have been widely used in many applications owing to their unique physical, chemical, and mechanical properties. For energy storage applications, the high surface area and high electrical conductivity make carbon nanomaterials promising in supercapacitor and battery systems. However, pristine carbon nanomaterials as electrodes are not applicable for grid-scale applications due to cost and energy density. There is a lack of approaches in efficiently manufacturing low-density carbon nanomaterials on a large scale. Besides, carbon nanomaterials themselves often achieve low energy densities comparing to other high-energy electrode materials such as sulfur and phosphorus. Proper manufacturing of carbon-sulfur and carbon-phosphorus nanocomposites for high-energy lithium-sulfur and sodium-ion batteries were demonstrated to tackle the challenges in cost, energy density, and scalable production for future grid-scale applications. For environmental applications, carbon nanomaterials that possess high surface area and porous feature have been demonstrated as good candidates for water treatment, such as heavy metal removal. To remove toxic hexavalent chromium from wastewater, incorporating nanomaterials to manufacture carbon nanocomposites for achieving high removal efficiency was illustrated in electrochemical reduction process.

2. Muralidharan, Nitin. Mechano-Electrochemistry for Advanced Energy Storage and Harvesting Devices.

Degree: PhD, Interdisciplinary Materials Science, 2018, Vanderbilt University

A fundamental perception in the energy storage community is that mechanical processes accompanying electrochemical processes are an unavoidable by-product. However, the coupling between mechanics and electrochemistry termed as the âmechano-electrochemical couplingâ is a powerful yet unexplored tool. Using principles of elastic strain engineering, we demonstrate controllable modulation of electrochemical parameters governing energy storage systems. Leveraging the shape memory properties of NiTi alloys, redox potentials and diffusion coefficient modulations for energy storage materials were achieved as a function of applied strain. Building off these principles, we developed electrochemical-mechanical energy harvesters for harnessing ambient mechanical energy at very low frequencies (<5 Hz), a regime where the conventional state-of the art piezoelectric and triboelectric energy harvesters have drastically reduced performances. We also highlight frequency tuning capabilities in this class of energy harvesters owing to the inherent differences in various battery electrode chemistries for use in human motion harvesting and sensing applications and multifunctional transient energy harvesting and storage devices. Additionally, to further illustrate the relationship between mechanical and electrochemical properties, we developed multifunctional structural supercapacitor and battery composites for use in load-bearing applications. Overall, these approaches provide paradigm shifting fundamental insights as well as create a framework for developing such multifunctional energy storage/harvesting architectures for a multitude of applications.
