This database compiles information from various publically available battery cell datasheets to provide a centralized and accessible repository for technical details of various real-world battery cells, including specifications, performance metrics, and technical characteristics. Our project aims to streamline research efforts, support informed decision-making, and foster advancements in battery technology by collecting these datasheets. We do not assume any liability for the completeness, correctness, and accuracy of the information. However, it is important to acknowledge the potential challenges of managing such a database given the still early, highly dynamic, and innovative battery market. Among others, ensuring data accuracy, data completeness, and timeliness is critical. Battery cell technologies are constantly evolving, requiring ongoing attention to maintain an up-to-date database with the latest specifications and cells. While we aimed to ensure that all records are complete, incomplete datasheets are limiting this effort and, thus, the full potential of the database. Last, standardization issues may present a challenge due to the absence of standardized reporting formats across manufacturers and countries. See "Notes" columns for comments. Unless otherwise stated, all values and parameters originate exclusively from the datasheets. Last, we highlight that it is important to consider potential uncertainties when using the information provided in cell datasheets. The values shown are primarily derived from standardized test environments and conditions and may not accurately reflect the actual real-world performance of the cells, which may vary significantly depending on ambient conditions (foremost temperature) and charge-discharge load profiles specific to applications and embedded use cases.
