The Electrolyte Genome Project
Traditional chemistry relies on intuition and experience to select a few materials that might work well for new electrolytes. The Electrolyte Genome streamlines this process by evaluating thousands of materials by simulation on the computer and choosing the most promising few for synthesis in the laboratory. Read More

SC15 High Performance Computing (HPC) Transforms Batteries
A new breakthrough battery—one that has significantly higher energy, lasts longer, and is cheaper and safer—will likely be impossible without a new material discovery. Kristin Persson and other JCESR scientists at Lawrence Berkeley National Laboratory are taking some of the guesswork out of the discovery process with the Electrolyte Genome Project. Read More

Electrolyte Genome Reveals New Instability Mechanism in Mg Electrolytes
imulations of a matrix of Mg salt and solvent combinations revealed a strong tendency to ion pair formation. Close association of the salt anion and cation within the first solvation shell, even at modest concentrations. Read More

Realizing the Electrolyte Genome
JCESR is building a highly sophisticated infrastructure for high-throughput evaluation of molecular properties. This involves coupling ab initio DFT methods with rapid classic molecular dynamics, calculations of redox potentials, and solvation structure while more detailed reactivity studies are carried out. Candidates that meet performance metrics for different types of battery applications (redox-flow, Li-air, Li-sulfur and multivalent) are prioritized for synthesis and testing. Read More
