AI comes up with battery design that uses 70 per cent less lithium


Researchers used AI to design a new material that they used to build a working battery – it requires up to 70 percent less lithium than some competing designs.

Artificial intelligence can accelerate the process of finding and testing new materials, and now researchers have used that ability to develop a battery that is less dependent on the costly mineral lithium. “The methods here are bleeding edge, in terms of machine learning tools, but what really elevates this is that things got made and tested,” says Rafael Gómez-Bombarelli at the Massachusetts Institute of Technology, who was not involved with the project. The data needed to train the AI for this type of work is often sparse, and materials other than battery components may require a more complex way of combining elements, he says.
