Revolutionizing Battery Innovation with Data and Simulation
The future of energy lies in smarter, more sustainable battery technology. As the demand for electric vehicles and energy storage surges, efficient battery performance is becoming increasingly crucial. Fraunhofer Institute for Industrial Mathematics ITWM is at the forefront of this transformation. By leveraging cutting-edge simulation tools, they are not only enhancing the inner workings of battery cells but also revolutionizing the way batteries are produced and maintained. Through a combination of data-driven modeling, predictive analytics, and innovative measurement technologies, Fraunhofer ITWM aims to push the boundaries of what modern batteries can achieve.
Simulating Electrode Microstructure for Better Battery Behavior
At the heart of every battery are its electrodes, and their microscopic structure plays a vital role in how a battery performs. Fraunhofer ITWM’s in-house BEST simulation software allows researchers to create detailed 3D models of electrode microstructures. These virtual models help predict how a battery behaves during charging and discharging. With this insight, engineers can identify key areas for performance improvement. Such simulation-based optimization supports the development of battery cells that are more efficient, powerful, and longer-lasting—key traits for electric vehicle success.
Tackling Battery Aging with Predictive Models
Battery aging is a complex challenge, driven by mechanical and chemical factors that reduce efficiency over time. Fraunhofer ITWM addresses this through integrated aging models within their BEST software. These tools analyze and forecast how storage and active use affect battery health. By simulating various aging scenarios, researchers can discover new ways to slow degradation. This approach not only improves battery durability but also supports more sustainable production practices by reducing waste and energy consumption in manufacturing.
Streamlining Production and Quality Control
Beyond design, Fraunhofer ITWM is enhancing battery manufacturing through simulation-based production tools and quality assurance systems. Their DiBaZ project unifies production stages by creating a “battery twin”—a digital model of the entire battery lifecycle. Tools like FeelMath, FLUID, and FOAM are used to optimize production steps such as electrode calendering, electrolyte wetting, and foam encapsulation. Furthermore, their advancement in terahertz measurement technology introduces a safer, non-contact method to inspect electrode coatings. These combined innovations reduce production errors and enable predictive energy management, ensuring batteries meet high performance and safety standards.
