Description

Solid-state batteries, or SSBs, are composed of solid electrolytes, as opposed to the liquid electrolytes in lithium-ion batteries. With high energy and power density levels, SSBs have the potential to be an effective way to electrify the transportation sector.

However, the lack of an existing framework for constructing SSBs poses a barrier to their economic feasibility.

To overcome this problem, ORNL researchers developed SolidPAC, a traditional spreadsheet and graphical user interface-based tool for examining and developing SSB properties. The open source toolkit includes general design guidelines to predict cell-, module- and pack-level energy densities based on user-defined parameters for the battery system.

SolidPAC offers specific design rationales for building highly energy-dense SSBs and will help determine battery metrics needed for SSBs to become comparable to lithium-ion batteries.

Funding for this project was provided by DOE’s Laboratory Directed Research and Development program.

ORNL’s Ilias Belharouak led the development. ORNL’s Marm Dixit, Nitin Muralidharan, Ruhul Amin, Rachid Essehli and Mahalingam Balasubramanian also contributed to SolidPAC.
