## Source Description

Pilot testing – This test was conducted initially to select appropriate AC amplitudes for main EIS experiment.  The tests were conducted on the single cylindrical cell made by Molicel of type INR-21700-P42A, labelled MCLE3231. The test was conducted over a frequency range of 0.1 Hz to 20 kHz using different current amplitudes 1 mA, 2 mA, 3 mA, 4 mA, 5 mA, 10 mA, 15 mA, 20 mA, 25 mA, 30 mA, 50 mA, 100 mA, 500 mA, and 1 A.
Variability testing - The data was collected on four cylindrical batteries made by Molicel of type INR-21700-P42A labelled as MCLI01, MCLI02, MCLI03, MCLI04. The experiments were performed at different SOC levels (80%, 60%, 40%, and 20%), various current amplitudes (30 mA, 50 mA, 100 mA, 500 mA, and 1 A), and rest times (30 minutes, 1 hour, and 2 hours). All tests were conducted over a frequency range of 0.01 Hz to 10 kHz. 
The experiments were conducted using two instruments Arbin battery cycler and Gamry 5000P potentiostat. The data collected during pilot testing are stored as CSV (Comma-Separated Values) files inside a folder named “Factor_CurrentAmplitude”. The data collected during the variability testing are in CSV format and are stored in a folder named “Factor_Resttime.”  

## Provenance And Validation

The mirror was created from the official Mendeley Data page and public file download URL. The downloaded archive size is `341733` bytes and its SHA-256 is `940c468e84666d1d8a42036d9bf53858591a295181d31f0cb1df9544946de414`, matching the checksum reported by Mendeley.

No source data transformation was performed. This dataset is a raw mirror pending BSEBench validation, and no benchmark, performance, SOTA, or leaderboard claims are made here.
