1. Qian, Ziwei. Effects of Ionic Liquid on Lithium Dendrite Growth.

Degree: MS, Department of Physics, 2018, Michigan Technological University

Lithium Dendrites, the microscopic fibers of lithium, often lead to a short circuit in lithium rechargeable batteries that may cause explosions and fires. However, the mechanism for dendrite growth in electrolytes remains unclear. To overcome this problem, we have developed a new Monte Carlo simulation method that simultaneously accounts for dendrite growth and the electrostatic potential in liquids with a minimal set of parameters. Our theory provides a fractal dimension that can be measured experimentally. We examine the fractal structure and the average height of dendrites growing in ionic liquids, with different ion concentration and voltage between electrodes. Our results show that ions can affect the fractal structure and the growth rate of dendrites, and dendrites grow more uniformly and slowly at high ionic strengths and under high voltage.

2. Shock, Cameron John. The Solvation Energy of Ions in a Stockmayer Fluid.

Degree: MS, Department of Physics, 2019, Michigan Technological University

The solvation of ions in polar solvents has been a long studied system since the early twentieth century. A common technique to calculate the energy associated with ion solvation is the Born Solvation energy equation. This equation assumes an ion is placed in an incompressible, homogeneous dielectric, which is not necessarily representative of a real system. In this work the Stockmayer Fluid Model is used in a molecular dynamics simulation through the software LAMMPS to check the quantitative correctness of the Born equation. It is also shown how solvation energies of ions placed in polymerized and non-polymerized solvents differ. It is shown that solvation energies in non-polymerized solvents are less negative than the predicted Born Solvation energy due to dielectric saturation effects, but are qualitatively similar. Solvation energies of polymerized solvents differ greatly from non-polymerized solvents and the predicted Born Solvation Energy. The reason for this is speculated to be due to compressibility of the solvents or structural and dipolar effects from polymer chains. It is also shown that the Stockmayer Fluid Model can be used to accurately predict experimental results for non-polymeric solvents. Advisors/Committee Members: Issei Nakamura.
