Abstract
Methods and systems for predicting lithium battery properties are presented. In one embodiment, a method includes an operation for creating an equivalent circuit of a battery cell, where the equivalent circuit includes a cathode equivalent circuit and a remainder equivalent circuit. Further, parameters for the cathode equivalent circuit are calculated using Quantum Mechanical (QM) simulation. Also included in the method are operations for obtaining parameters for the remainder equivalent circuit via experimentation, and for calculating the lithium battery properties using the equivalent circuit.
