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.
