Motivation

The "Synthetic Lithium-Ion Battery Degradation Dataset for Remaining Useful Life Estimation" was created to support the development of machine learning models that can predict the remaining service life of lithium-ion based batteries. Due to the limited availability of real-world ageing data and freely accessible measurement data on battery ageing, synthetic ageing data was generated using physics-based simulation.

Description

This dataset contains ageing simulations of lithium-ion batteries, which were carried out using the PyBaMM framework (https://pybamm.org) . The simulations covered cell ageing during simple charge-discharge cycles as well as WLTC driving cycle simulations. The ageing simulations are based on the official PyBaMM example "Modelling coupled degradation mechanisms in PyBaMM" (https://docs.pybamm.org/en/v25.8.0/source/examples/notebooks/models/coupled-degradation.html). The simulations use the built-in DFN (Doyle-Fuller-Newman) model in PyBaMM with degradation mechanisms enabled. The "OKane2022" parameter set for the LG M50 cell, which is built into PyBaMM, was used as the starting point for parameterising the simulation model. However, to vary the ageing process, some of the ageing parameters were adjusted, as can be seen in the simulation metadata.

Dataset Structure

The dataset comprises multiple studies, each of which consists of several simulations of individual battery cells. The simulations within a given study share certain parameters, such as the type of the test cycle. The differences between the simulations within a study lie in the details.  Therefore, the metadata for each individual simulation must always be consulted.
