SolidPAC is an interactive battery-on-demand energy density estimator for solid-state batteries

Abstract

Solid-state batteries hold the promise to be highly impactful next-generation technologies for high-energy and -power-density rechargeable battery applications. It is crucial to identify the metrics that an emerging battery technology should fulfill to achieve parity with conventional Li-ion batteries, primarily in terms of energy density. However, limited approaches exist today to assess and extrapolate the impact of battery designs and choices of cell components on the cell-level energy density of a solid-state battery. Herein, we introduce the Solid-State Battery Performance Analyzer and Calculator (SolidPAC), an interactive experimental toolkit to enable the design of a solid-state battery for user-specified application requirements. The toolkit is flexible enough to assist the battery community in quantifying the impact of materials chemistry and fractions, electrode thicknesses and loadings, and electron flows on cell energy density and costs and in utilizing inverse engineering concepts to correlate the cell energy density output to materials and cell design inputs. • SolidPAC demonstrated as a toolkit for solid-state battery design • Evaluate implications of material selection and design criteria on energy density • Enables inverse design of solid-state batteries for user-specified applications Dixit et al. report a toolkit that enables the design of solid-state batteries that cater to specific user-specified metrics. The paper details the development approach and implementation of the toolkit and provides example calculations as well as an evaluation of experimental literature data to demonstrate the applicability of the developed toolkit.
