Documentation

This repository contains the measurement data presented in "Performance Characterization of Lithium-Ion Battery Cells Within Restricted Operating Range Using an Extended Ragone Plot."

The performance characterization was conducted on three lithium-ion battery cell types, each with two samples. In the publication only datasets from the following cells are included: #1: SCiB-23Ah-01, #2: SLPB8644143-353, #3: M1B-1223-01. The measurements were performed using a Scienlab SL60/300/18BT2C battery test system in combination with a BINDER type MK 720 temperature chamber. Further details about the battery cells, the experimental setup and procedures are available in the publication. An uncertainty analysis for these measurements is included in the supplementary material of the publication.

Note: Please cite the referenced publication when using these datasets in your work.

Usage instructions

1. Raw test reports are stored in the test reports directory as *.csv and *.info.txt files. These files contain the following measurement signals:
   • Time, Test step, ind_T, ind_U, ind_xP, E [J], Eneg [J], Epos [J], I [A], P [W], Q [As], Qneg [As], Qpos [As], T_1 [°C], T_2 [°C], T_3 [°C], T_Clima [°C], U [V]
2. The test reports are structured and consolidated into an HDF5 file (Scienlab.h5) for efficient storage and analysis. This HDF5 file can be processed using the HDF5 Data Analysis and Visualization Toolkit, provided in this repository.
   • The Python script hdf5_main.py is included for processing and visualizing the datasets.
   • PowerTemperatureTest_dis-Umax datasets contain cyclization data from multiple constant power (CP) discharges and standardized constant current constant voltage (CCCV) charges, with varying end-of-charge voltages.
   • OCVTest datasets contain low-current galvanostatic data required for performance characterization via reconstruction-based approaches. The test protocol is extensively described in the publication.
