Data for "Managing silicon burn-out via onboard material diagnostics for durable high-energy density batteries"

This dataset accompanies the Joule manuscript “Managing silicon burn-out via onboard material diagnostics for durable high-energy density batteries.” If you use this dataset, please cite the accompanying Joule article: https://doi.org/10.1016/j.joule.2026.102531 Associated code package:https://doi.org/10.5281/zenodo.20259383 The archive contains the data folder required to run the analysis and plotting workflows in the associated code repository. After downloading, users should unzip the archive and place the extracted data folder at the root of the associated code repository. 1. Lifetime data: The dataset includes cycling and calendar-aging data from 60 NMC622/SiO-graphite pouch cells tested under 24 operating conditions, including different pretension, temperature, C-rate, and state-of-charge window protocols. The lifetime data include time-series records such as current, voltage, temperature, capacity/throughput, and protocol labels, together with cycle-level metrics and the experimental test matrix. 2. BOL/EOL C-rate diagnostic data: The dataset includes beginning-of-life (BOL) and end-of-life (EOL) C-rate diagnostic files used to evaluate material-specific diagnostic performance across charging rates, silicon-OCP treatment, discarded initial charge data, and kinetic compensation settings. 3. Electrode OCP reference data: The dataset includes electrode open-circuit-potential (OCP) reference files for graphite, NMC622, silicon, reconstructed silicon, and the composite anode. These files support the MSMR silicon-OCP identification, eSOH diagnostics, transition-SoC calculation, and figure-generation workflows. A SHA256 checksum file is provided to verify the integrity of the downloaded archive. The dataset is released under the Creative Commons Attribution 4.0 International License (CC BY 4.0).
