To virtually design reliable high-performance Lithium-ion cells, you need to consider three-dimensional anisotropic effects across battery cell layers. Currently available simulation approaches neglect such effects or make crucial compromising simplifications by reducing the problem to representative 2-dimensional battery layer descriptions.

With Simcenter STAR-CCM+ 2310, we are releasing a new unique 3D cell design capability to design lithium-ion battery cells with high geometric and physical fidelity. This new high-fidelity cell design template allows for the design of Lithium-ion cells in full 3D, with geometrically resolved electrode layers, separators, and tabs.

The templated simulation leverages easy-to-use dedicated custom trees and the new Stages feature for a customized and tailored workflow for cell designers, with industry-standard terminology and units. It provides you with a simplified mesh setup with a few inputs and clicks and supports dedicated industry-standard post-processing to facilitate the analysis from the simulation results. The capability is driven by simulation templates for industry standard cell shapes. With Simcenter STAR-CCM+ 2310 we release the stack cell template; cylindrical, and prismatic wound cell templates will be available soon. Along with this automated workflow, the 3D cell design capability provides highly accurate electrochemical models via an enhanced physics-based model of the initial Newman-Doyle-Fuller formulation.

The 3D cell design capability gives you detailed insights into cell performance quickly. Investigate in-plane and through-thickness ion concentration to understand local and edge effects, or predict the effect of tabs and surface cooling to design better battery cells faster.
