SIT Battery Data: Degradation of 22 Prismatic LFP Cells Under Four Conditions

Twenty-two large-format prismatic lithium iron phosphate cells were cycled under four distinct operating conditions over an approximately 18-month campaign from October 2022 to March 2024. Data were recorded at 1-second resolution using industrial-grade battery cyclers and a programmable environmental chamber, with a dedicated thermocouple sensor assigned to every cell. The dataset was collected at the Singapore Institute of Technology with support from the Singapore Energy Market Authority.

Use Cases

• Capacity fade modelling based on multi-condition cycling protocols
• State-of-health estimation based on electrical and thermal time-series data
• Remaining useful life prediction using cell degradation trajectories
• Thermal-aware prognostics based on dedicated per-cell surface temperature measurements
• Cell-to-cell variability studies across 22 large-format prismatic LFP cells

Strengths

• Data from 22 large-format prismatic LiFePO₄ cells provides a basis for variability analysis
• Time-series recorded at 1-second resolution with dedicated per-cell thermal monitoring
• Cycling performed under four distinct operating conditions over an 18-month period

Limitations

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