3D Simulation of Battery Materials Improves Battery Design
- Summary
- Researchers at Purdue University have developed a novel, 3-D simulation technology, called Batts3D, which can directly predict the performance, response, and reliability of battery materials. By using real or computer generated microstructures (architectures, geometries, and topologies), this technology can simulate properties such as local lithium accumulation, chemical stresses, voltage, Joule-heating generation, true macroscopic delivered power, charge, and energy density. Microscopically-average properties, such as tortuosity and reactive area density, can also be readily quantified from the simulations. Batts3D improves upon traditional approaches by explicitly including material inhomogeneities while also describing commercial relevant time scales. Consequently, new and advanced designs can be explored and tested to maximize performance and reliability.

- *Abstract
-
- *Background
- With the emergence of electric vehicles and the increasing demand for advanced battery technologies, there is a need for better methods to develop these technologies. Battery testing and validation makes up a large part of the battery development process. Traditional approaches use average material properties and assume a spatially uniform distribution of perfectly spherical particles to predict the average response of a statistically representative battery. Such approaches are not amenable to understanding the effects of fabrication, advanced particle morphologies, and concurrently occurring phase transformation. They are also incapable of exploring cutting edge new designs and alternative architectures.
