Why Battery Simulation Matters

Lithium-ion batteries are key energy storage solutions for a broad spectrum of applications, from portable electronics to the automotive sector. Their popularity is driven by high energy density, low maintenance, and excellent electrochemical performance. Simulation of thermal-electrochemical behavior is crucial for developing reliable battery systems, improving efficiency, and predicting degradation, aging, and thermal runaway events.
