Summary

IonSense-QKG is a quantum-readiness metadata framework designed to facilitate the discovery of public lithium-ion battery datasets for hybrid quantum-classical machine learning workflows. It addresses the substantial variability in existing datasets regarding chemistry, modality, scale, and preprocessing. The framework enriches records from the EV-Battery-IonSense index with quantum-relevant metadata, including task type, sensing modality, chemistry, label availability, sequence type, preprocessing requirements, candidate quantum encodings, estimated qubit range, and NISQ feasibility. It introduces a transparent Quantum Readiness Score to rank datasets, serving as a heuristic for selecting resources for future hybrid quantum-classical battery benchmarks. IonSense-QKG enables query-based discovery to identify datasets suitable for compact quantum feature maps, quantum time-series workflows, and limited-label anomaly detection. The released artifact includes metadata tables, scoring scripts, and SQL-style query examples, establishing a reproducible foundation for data-centric quantum battery analytics.
