Aionics Advanced Molecular Property Prediction Models

Single-substance molecular property prediction models trained using state-of-the-art graph neural networks (GNNs).

Models

These proprietary models are built by Aionics utilizing methodology developed in Prof. Venkat Viswanathan’s lab at Carnegie Mellon University as part of the ARPA-E DIFFERENTIATE program . The intellectual property from CMU is exclusively licensed to Aionics and represents one of the most advanced molecular property optimization capabilities for electrolyte design.

The six property models currently available for use are:

Melting Point

The Melting Point (MP) indicates the lowest temperature at which the electrolyte solvent remains in a liquid state. The MP model is trained on ~104 experimental data points and predicts the temperature of melting in degrees Celsius.

Boiling Point

The Boiling Point (BP) indicates the highest temperature at which the electrolyte solvent remains in a liquid state. The BP model is trained on ~104 experimental data points and predicts the temperature of boiling in degrees Celsius.

Flash Point

The Flash Point (FP) is a measure of the flammability of a solvent or additive. The FP model is trained on ~104 experimental data points and predicts the lowest temperature, in degrees Celsius, at which a solid or liquid can produce enough vapor to form a flammable air-vapor mixture.

Dipole Moment

The Dipole Moment provides a useful measure of the solubility of an additive molecule in the electrolyte solvent. The Dipole Moment model is trained on ~105 DFT-computed data points and predicts the dipole moment in Debye.

HOMO

HOMO provides a measure of the oxidative stability of a solvent. The HOMO model is trained on ~105 DFT-computed data points and predicts the highest occupied molecular orbital energy of a molecule in eV.

LUMO

LUMO provides a measure of the reductive stability of a solvent. The LUMO model is trained on ~105 DFT-computed data points and predicts the lowest occupied molecular orbital energy of a molecule in eV.
