Challenges in Battery Cell Design
It is critical for battery manufacturers to increase cell energy and power density. Achieving a balance between high power density and long cycle life is a key challenge in battery design, often requiring careful optimization of materials, electrode structure, and thermal management systems. Another key challenge is to reduce the overall cost of battery cells by optimizing weight-volume ratio.
Engineering Solution
The solution approach to improve cell and electrode performance deployed by Ansys has four pillars:
1. Fast-preprocessing: Using fully resolved porous electrodes structure (this can be achieved by robust Fluent Meshing tool)
