EBook- Better Battery Design Using AI

Better battery design with AI summary

Next-generation batteries with high energy density, quick charging capacity, and long lifetimes are needed to enable the energy transition and slow the effects of climate change. The materials challenges involved in battery development are complex and span multiple scales from the molecular and chemical composition of the ceramics used in lithium-ion battery cathodes to the coatings on the cooling channels inside battery packs. This paper explores how AI can be used to reach achieve superior battery performance targets quickly, through material development, battery configuration optimization, and improved battery testing.

Battery cross section showing the components of a battery system that can be optimized with AI.

Case study: Cathode Configuration optimization

In this paper, we describe a case study a for replacing N-methyl pyrrolidinone (NMP) as a cathode slurry solvent using AI-driven R&D workflows based on regulatory and sustainability concerns around NMP.

We walk through the primary steps to applying an AI-driven workflow including:

Curating and structuring a product development dataset
Building a graphical AI model that incorporates scientific domain knowledge
Training the AI model on the structured battery dataset
Evaluating model performance
Defining a search space to constrain ingredients, labels, and processing parameters
Combining steps 1-5 in an an inverse design workflow to identify novel cathode slurry solvents that hit performance and sustainability targets
