Cyclic Aging Data for 48 Commercial NMC/Graphite Lithium-Ion Cells

48 commercial Sanyo/Panasonic UR18650E cylindrical cells were aged under identical conditions. The dataset contains time-series measurements of current, voltage, and temperature from cyclic aging tests, along with reference performance tests conducted at regular intervals. The data was collected by Dirk Uwe Sauer of RWTH Aachen University.

Use Cases

• Predicting battery state-of-health based on time-series voltage and current data.
• Developing aging models for NMC/graphite cells using cyclic test data.
• Benchmarking battery performance algorithms against a controlled, multi-cell experimental dataset.
• Analyzing the relationship between operating temperature and capacity fade over time.

Strengths

• Data from 48 identical cells aged under the same controlled profile.
• Includes comprehensive begin-of-life (BOL) characterization and regular reference performance tests (RPT).
• Cells are commercially available, representing a mature manufacturing process.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
