Presentation transcript:

Highly Accurate Li-ion Battery Simulation Traditional means of evaluating battery performance with advanced chemistries do not provide sufficient information to allow researchers to optimize them Researchers turned to multiphysics simulation to achieve a deeper understanding of what is going on inside the cells Rather than work with an equivalent circuit model, researchers decided to create a physics-based model of a LiFePO4/Li half cell Including an Electric Double Layer allowed for a perfect agreement between simulation results at high frequencies. Simulation results have been proven useful to useful for obtaining some critical physical values and pointed to importance of including the electric double layer in simulations COMSOL News 2013: Mikael Cugnet, French Atomic And Alternative Energy Commission (CEA), France
