Executive Summary

This repository provides Matlab code for the Single Particle Model with Electrolyte (SPMe). The SPMe can be run and edited from filename spme.m. Future versions will include the Single Particle Model with Electrolyte and Temperature (SPMeT) dynamics. The SPMe model code is based upon the equations in the publication below.

Features

Specifically, the code models the following dynamics:

• Solid-phase lithium diffusion
• Electrolyte-phase lithium diffusion
• Assumes isothermal operation (SPMe only)
• Surface and bulk concentrations of lithium in solid-phase single particles
• Voltage
