0D Physics-Based Modeling of High Energy Lithium Metal Batteries with Pulsing Requirements

Abstract

Lithium metal batteries are promising candidates for high energy storage solutions. To further increase capacity, electrolyte components can have a secondary function of storing charge through electrochemical reactions. This work focuses on modeling high-energy lithium metal anode and metal oxide cathode material and potentially other materials with additional capacity from electrolyte components. Physics-based modeling can be utilized to explore design space and predict battery performance under various conditions. This work utilizes a zero-dimensional model with thermodynamics, kinetics, transport, and morphology changes of the solution and solid-phase species. The effect of the additional electrolyte components on the transport, capacity, and voltage behavior will be explored. Pulse power will also be discussed, and this talk may include comparisons to experimental data.
