Watch the complete tutorial
The video is the primary learning resource for this page. Use the structured notes below to track the workflow, validation points and research extensions while you follow the demonstration.
What you will learn
- Set up a Li-ion battery model with electrochemical and degradation-related parameters required for aging analysis.
- Represent SEI-growth and lithium-plating effects in a controlled simulation workflow.
- Track capacity fade, resistance/overpotential changes and degradation indicators across cycling or accelerated-use scenarios.
- Use simulated degradation trends to construct a transparent remaining-useful-life assessment and compare operating conditions.
Tutorial roadmap
- Baseline Li-ion electrochemistry — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
- SEI growth mechanism — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
- Lithium plating conditions — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
- Cycling and accelerated aging cases — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
- Capacity fade and degradation metrics — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
- RUL interpretation and validation — follow this stage in the video and record the important assumptions, settings and outputs so the workflow can be reproduced.
Model, software and prerequisites
This tutorial is associated with COMSOL 6.4 and the Battery Modeling & Degradation technical area. Before reproducing the workflow, confirm the software version, required modules or toolboxes, source data, material/physical parameters and any external dependencies shown in the tutorial.
For research use, keep a short parameter table while following the video. This makes later sensitivity analysis, troubleshooting and thesis documentation much easier.
Validation and results to check
The recommended validation evidence includes SOC estimation or tracking error, charge/discharge power, voltage deviation, current ripple. The strongest validation comes from repeating identical test cases for the reference and proposed methods, then explaining why the measured differences occur. The final discussion should also explain sensitivity to different initial SOC conditions, power or current limit activation.
- Primary field distribution — connect the output to a defined case, parameter setting and acceptance or comparison metric.
- Derived global / point values — connect the output to a defined case, parameter setting and acceptance or comparison metric.
- Geometry or parameter sweep — connect the output to a defined case, parameter setting and acceptance or comparison metric.
- Mesh / solver convergence evidence — connect the output to a defined case, parameter setting and acceptance or comparison metric.
- Comparison of operating or design cases — connect the output to a defined case, parameter setting and acceptance or comparison metric.
How engineering scholars can extend this tutorial
The tutorial is a starting point rather than a substitute for a research contribution. For thesis or journal-oriented work, retain the verified baseline and extend it with a clearly stated limitation, new method and quantitative comparison.
- hybrid SOC/SOH estimation
- degradation-aware energy management
- thermal-constrained charging or dispatch
- multi-objective sizing/control with lifecycle and grid metrics

Questions about this tutorial
Who is this tutorial for?
This tutorial is designed for engineering students, postgraduate scholars, PhD researchers and technical learners who want a reproducible workflow rather than only a final result.
What should I verify while following the tutorial?
Record the software version, model or workflow assumptions, key parameters, solver or training settings, operating cases and the quantitative outputs used to confirm that the result is technically consistent.
Can this tutorial be extended into thesis or research work?
Yes. Use the tutorial as a baseline, then define a literature-supported limitation, add a measurable modification, test sensitivity or stressed conditions and compare the result against the same baseline assumptions.
