Aionics

Aionics uses machine learning and physics-based quantum-mechanical simulation to design custom chemical formulations, primarily electrolytes for high-performance batteries. Its platform screens billions of candidate molecules and formulations against a target performance profile, then works with chemical partners to source and commercialize the winners. In June 2025 the company launched Artificial Molecular Intelligence (AMI), a real-time autonomous formulation-screening platform built on MIST, a foundation model trained on over two billion SMILES molecular representations. Aionics was co-founded by Austin Sendek, Venkat Viswanathan, and Lenson Pellouchoud, is based in Palo Alto, California, and licenses battery electrolyte design software from Carnegie Mellon University.

Combines a molecular foundation model with physics-based simulation and a chemical supply chain, so customers get not just a screened candidate formulation but a sourceable material - and the CMU-licensed electrolyte design software underpinning it.
