Optimising the safety and performance of the batteries used in electric vehicles and portable devices is complex, as batteries are described by an interplay of solid-state physics, chemistry, mechanics and much more.
In a keynote talk from COMSOL Day: Automotive, Maurits Houck from Echion Technologies discusses how to use multiphysics simulation to optimise complex battery designs. During the talk, Houck goes over the setup of a Newman pseudo-two-dimensional (P2D) model of a battery cell, which can be used to predict its final experimental performance. It also provides insight into what happens inside the cell, which is difficult to measure experimentally. A 3D battery model is also explored.
Maurits Houck is a PhD student at the University of Cambridge, where he studies batteries in collaboration with Echion Technologies Ltd, a spinoff company of the University of Cambridge that is developing a new type of fast-charging battery material.
