Artificial intelligence helped design a new type of battery
Supercomputing and AI cut the early discovery steps from decades to just 80 hours. The process led to a new solid electrolyte.
MS-PS1-5
Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
