Abstract
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.
